In general, the strength estimated by current design guidelines is conservative for these members when flexural-torsional buckling (FTB) is the first global buckling mode, as the post-buckling strength of this mode is not accounted for in the global buckling strength equations. The initial part of this paper reports the results of an experimental and numerical study of CFS-LA members undergoing independent FTB. The modifications are suggested to global buckling strength equations based on these results. Subsequently, the reduction in the ultimate strength from strength corresponding to independent buckling modes for LA members undergoing interaction between buckling modes such as local-flexural torsional, flexural-flexural torsional, local-flexural, and local-flexural torsional-flexural are studied systematically using finite element analysis results. A simple and more accurate interaction equation that accounts for the above interactions between buckling modes in CFS-LA compression members is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling%20interactions" title="buckling interactions">buckling interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=cold-formed%20steel" title=" cold-formed steel"> cold-formed steel</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural-torsional%20buckling" title=" flexural-torsional buckling"> flexural-torsional buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=lipped%20angle" title=" lipped angle"> lipped angle</a> </p> <a href="https://publications.waset.org/abstracts/172729/interaction-of-local-flexural-torsional-and-flexural-buckling-in-cold-formed-steel-lipped-angle-compression-members" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172729.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30182</span> Comparative Study of Numerical and Analytical Buckling Analysis of a Steel Column with Various Slenderness Ratios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lahlou%20Dahmani">Lahlou Dahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Warda%20Mekiri"> Warda Mekiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Boudjemia"> Ahmed Boudjemia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This scientific paper explores the comparison between the ultimate buckling load obtained through the Eurocode 3 methodology and the ultimate buckling load obtained through finite element simulations for steel columns under compression. The study aims to provide insights into the adequacy of the design rules proposed in Eurocode 3 for different slenderness ratios. The finite element simulations with the Ansys commercial program involve a geometrical and material non-linear analysis of the columns with imperfections. The loss of equilibrium is generally caused by the geometrically nonlinear effects where the column begins to buckle and lose its stability when the load reaches a certain critical value. The linear buckling analysis predicts the theoretical buckling strength of an elastic structure but the nonlinear one is more accurate with taking into account the initial imperfection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ansys" title="Ansys">Ansys</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20buckling" title=" linear buckling"> linear buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=eigen%20value" title=" eigen value"> eigen value</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20buckling" title=" nonlinear buckling"> nonlinear buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=slenderness%20ratio" title=" slenderness ratio"> slenderness ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=Eurocode%203" title=" Eurocode 3"> Eurocode 3</a> </p> <a href="https://publications.waset.org/abstracts/192964/comparative-study-of-numerical-and-analytical-buckling-analysis-of-a-steel-column-with-various-slenderness-ratios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192964.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">19</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30181</span> Lateral Torsional Buckling of Steel Thin-Walled Beams with Lateral Restraints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Bal%C3%A1zs">Ivan Balázs</a>, <a href="https://publications.waset.org/abstracts/search?q=Jind%C5%99ich%20Melcher"> Jindřich Melcher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Metal thin-walled members have been widely used in building industry. Usually they are utilized as purlins, girts or ceiling beams. Due to slenderness of thin-walled cross-sections these structural members are prone to stability problems (e.g. flexural buckling, lateral torsional buckling). If buckling is not constructionally prevented their resistance is limited by buckling strength. In practice planar members of roof or wall cladding can be attached to thin-walled members. These elements reduce displacement of thin-walled members and therefore increase their buckling strength. If this effect is taken into static assessment more economical sections of thin-walled members might be utilized and certain savings of material might be achieved. This paper focuses on problem of determination of critical load of steel thin-walled beams with lateral continuous restraint which is crucial for lateral torsional buckling assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beam" title="beam">beam</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=steel" title=" steel"> steel</a> </p> <a href="https://publications.waset.org/abstracts/31094/lateral-torsional-buckling-of-steel-thin-walled-beams-with-lateral-restraints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31094.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30180</span> Lateral Buckling of Nanoparticle Additive Composite Beams </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCrkan%20%C5%9Eakar">Gürkan Şakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Akg%C3%BCn%20Alsaran"> Akgün Alsaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Emrah%20E.%20%C3%96zbaldan"> Emrah E.

Buckling loads determined from theoretical methods and software is compared for 2D one bay, one and two stories steel frames. To consider actual condition, buckling loads of three steel frames that have various dimensions are calculated and compared. Also, uncertainties that exist in loading and modeling of structures such as geometrical imperfection, yield stress, and modulus of elasticity in buckling load of 2D framed steel structures have been studied. By performing these uncertainties to each reliability analysis procedures (first-order, second-order, and simulation methods of reliability), one index of reliability from each procedure is determined.

The partial differential equations that govern kinematic behavior of shells produce five coupled differential equations. The basic displacement and rotational unknowns are similar to first order shear deformation theory---three displacement in spatial space, and two rotations about in-plane axes. No drilling degree of freedom is considered. Boundary conditions are considered as complete hinge in all edges so that the panel respond on thermal inductions. Two sets of double Fourier series are considered in the analytical solution process. The sets are selected that satisfy mixed type of natural boundary conditions. Numerical results are presented for the first 10 eigenvalues, and first 10 mode shapes for Ux, Uy, and Uz components.

The Finite Strip Method is used as tool for the analysis. This method uses finite strip elastic, foundation, and geometric matrices to build the assembly matrices for the whole structure, then after introducing boundary conditions at supports, the resulting reduced matrices is transformed into a standard Eigenvalue-Eigenvector problem. The solution of this problem will enable the determination of the buckling load, the associated buckling modes and the buckling wave length. To carry out the buckling analysis starting from the elastic, foundation, and geometric stiffness matrices for each strip a computer program FORTRAN list is developed. Since stiffness matrices are function of wave length of buckling, the computer program used an iteration procedure to find the critical buckling stress for each value of foundation modulus and for each boundary condition. The results showed the use of elastic medium to support plates subject to axial load increase a great deal the buckling load, the results found are very close with those obtained by other analytical methods and experimental work. The results also showed that foundation compensates the effect of the weakness of some types of constraint of side support and maximum benefit found for plate with one side simply supported the other free. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling" title="buckling">buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20strip" title=" finite strip"> finite strip</a>, <a href="https://publications.waset.org/abstracts/search?q=different%20sides%20support" title=" different sides support"> different sides support</a>, <a href="https://publications.waset.org/abstracts/search?q=plates%20on%20foundation" title=" plates on foundation"> plates on foundation</a> </p> <a href="https://publications.waset.org/abstracts/1681/buckling-of-plates-on-foundation-with-different-types-of-sides-support" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1681.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30176</span> Correction Requirement to AISC Design Guide 31: Case Study of Web Post Buckling Design for Castellated Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kitjapat%20Phuvoravan">Kitjapat Phuvoravan</a>, <a href="https://publications.waset.org/abstracts/search?q=Phattaraphong%20Ponsorn"> Phattaraphong Ponsorn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the design of Castellated beams (CB), the web post buckling acted by horizontal shear force is one of the important failure modes that have to be considered. It is also a dominant governing mode when design following the AISC 31 design guideline which is just published. However, the equation of the web post buckling given by the guideline is still questionable for most of the engineers. So the purpose of this paper is to study and provide a proposed equation for design the web post buckling with more simplified and convenient to use. The study is also including the improper of the safety factor given by the guideline. The proposed design equation is acquired by regression method based on the results of finite element analysis. An amount of Cellular beam simulated to study is modelled by using shell element, analysis with both geometric and material nonlinearity. The results of the study show that the use of the proposed equation to design the web post buckling in Castellated beams is more simple and precise for computation than the equations provided from the guideline. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=castellated%20beam" title="castellated beam">castellated beam</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20opening" title=" web opening"> web opening</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20post%20buckling" title=" web post buckling"> web post buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20equation" title=" design equation"> design equation</a> </p> <a href="https://publications.waset.org/abstracts/82654/correction-requirement-to-aisc-design-guide-31-case-study-of-web-post-buckling-design-for-castellated-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82654.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30175</span> Numerical Buckling of Composite Cylindrical Shells under Axial Compression Using Asymmetric Meshing Technique (AMT)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zia%20R.%20Tahir">Zia R.

Mandal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the details of a numerical study of buckling and post buckling behaviour of laminated carbon fiber reinforced plastic (CFRP) thin-walled cylindrical shell under axial compression using asymmetric meshing technique (AMT) by ABAQUS. AMT is considered to be a new perturbation method to introduce disturbance without changing geometry, boundary conditions or loading conditions. Asymmetric meshing affects both predicted buckling load and buckling mode shapes. Cylindrical shell having lay-up orientation [0°/+45°/-45°/0°] with radius to thickness ratio (R/t) equal to 265 and length to radius ratio (L/R) equal to 1.5 is analysed numerically. A series of numerical simulations (experiments) are carried out with symmetric and asymmetric meshing to study the effect of asymmetric meshing on predicted buckling behaviour. Asymmetric meshing technique is employed in both axial direction and circumferential direction separately using two different methods, first by changing the shell element size and varying the total number elements, and second by varying the shell element size and keeping total number of elements constant. The results of linear analysis (Eigenvalue analysis) and non-linear analysis (Riks analysis) using symmetric meshing agree well with analytical results. The results of numerical analysis are presented in form of non-dimensional load factor, which is the ratio of buckling load using asymmetric meshing technique to buckling load using symmetric meshing technique. Using AMT, load factor has about 2% variation for linear eigenvalue analysis and about 2% variation for non-linear Riks analysis. The behaviour of load end-shortening curve for pre-buckling is same for both symmetric and asymmetric meshing but for asymmetric meshing curve behaviour in post-buckling becomes extraordinarily complex. The major conclusions are: different methods of AMT have small influence on predicted buckling load and significant influence on load displacement curve behaviour in post buckling; AMT in axial direction and AMT in circumferential direction have different influence on buckling load and load displacement curve in post-buckling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFRP%20composite%20cylindrical%20shell" title="CFRP composite cylindrical shell">CFRP composite cylindrical shell</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20meshing%20technique" title=" asymmetric meshing technique"> asymmetric meshing technique</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20buckling" title=" primary buckling"> primary buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20buckling" title=" secondary buckling"> secondary buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20eigenvalue%20analysis" title=" linear eigenvalue analysis"> linear eigenvalue analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20riks%20analysis" title=" non-linear riks analysis"> non-linear riks analysis</a> </p> <a href="https://publications.waset.org/abstracts/16401/numerical-buckling-of-composite-cylindrical-shells-under-axial-compression-using-asymmetric-meshing-technique-amt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16401.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30174</span> Critical Buckling Load of Carbon Nanotube with Non-Local Timoshenko Beam Using the Differential Transform Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tayeb%20Bensattalah">Tayeb Bensattalah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Zidour"> Mohamed Zidour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ait%20Amar%20Meziane"> Mohamed Ait Amar Meziane</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahar%20Hassaine%20Daouadji"> Tahar Hassaine Daouadji</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelouahed%20Tounsi"> Abdelouahed Tounsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the Differential Transform Method (DTM) is employed to predict and to analysis the non-local critical buckling loads of carbon nanotubes with various end conditions and the non-local Timoshenko beam described by single differential equation.

As a first step, in the case of a stiffener having an inclined part on the flange, experimental and nonlinear finite element analysis are carried out for three different upright lengths. In the uprights with long length, global buckling is observed while distortional buckling and local buckling are observed in the uprights with medium length and those with short length, respectively. After this point, the study is divided into two groups. One of these groups is the case where the stiffener on the flange is folded at 90°. For this case, four different distances of the stiffener from the web are taken into account. In the other group, the case where different depth of stiffener on the web is considered. Combining experimental and finite element results, the cross-section giving the ultimate critical buckling load is selected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel" title="steel">steel</a>, <a href="https://publications.waset.org/abstracts/search?q=upright" title=" upright"> upright</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=modes" title=" modes"> modes</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20finite%20element%20analysis" title=" nonlinear finite element analysis"> nonlinear finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/64991/improvement-of-buckling-behavior-of-cold-formed-steel-uprights-with-open-cross-section-used-in-storage-rack-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64991.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">260</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30172</span> Influence of Hygro-Thermo-Mechanical Loading on Buckling and Vibrational Behavior of FG-CNT Composite Beam with Temperature Dependent Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Kumar">Puneet Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonnalagadda%20Srinivas"> Jonnalagadda Srinivas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The authors report here vibration and buckling analysis of functionally graded carbon nanotube-polymer composite (FG-CNTPC) beams under hygro-thermo-mechanical environments using higher order shear deformation theory. The material properties of CNT and polymer matrix are often affected by temperature and moisture content. A micromechanical model with agglomeration effect is employed to compute the elastic, thermal and moisture properties of the composite beam. The governing differential equation of FG-CNTRPC beam is developed using higher-order shear deformation theory to account shear deformation effects. The elastic, thermal and hygroscopic strain terms are derived from variational principles. Moreover, thermal and hygroscopic loads are determined by considering uniform, linear and sinusoidal variation of temperature and moisture content through the thickness. Differential equations of motion are formulated as an eigenvalue problem using appropriate displacement fields and solved by using finite element modeling. The obtained results of natural frequencies and critical buckling loads show a good agreement with published data. The numerical illustrations elaborate the dynamic as well as buckling behavior under uniaxial load for different environmental conditions, boundary conditions and volume fraction distribution profile, beam slenderness ratio. Further, comparisons are shown at different boundary conditions, temperatures, degree of moisture content, volume fraction as well as agglomeration of CNTs, slenderness ratio of beam for different shear deformation theories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hygrothermal%20effect" title="hygrothermal effect">hygrothermal effect</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title=" free vibration"> free vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling%20load" title=" buckling load"> buckling load</a>, <a href="https://publications.waset.org/abstracts/search?q=agglomeration" title=" agglomeration"> agglomeration</a> </p> <a href="https://publications.waset.org/abstracts/56592/influence-of-hygro-thermo-mechanical-loading-on-buckling-and-vibrational-behavior-of-fg-cnt-composite-beam-with-temperature-dependent-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56592.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30171</span> Dealing with Buckling Effect in Snorkel by Finite Element Analysis: A Life Enhancement Approach in CAS-OB Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Subodh%20Nath%20Patel">Subodh Nath Patel</a>, <a href="https://publications.waset.org/abstracts/search?q=Raja%20Raman"> Raja Raman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mananshi%20Adhikary"> Mananshi Adhikary</a>, <a href="https://publications.waset.org/abstracts/search?q=Jitendra%20Mathur"> Jitendra Mathur</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Bhattacharyya"> Sandip Bhattacharyya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The composition adjustment by sealed argon bubbling–oxygen blowing (CAS-OB) process is a process designed for adjusting steel composition and temperature during secondary metallurgy. One of the equipment in the said process is a snorkel or bell, fixed to a movable bracket. Snorkel serves the purpose of feeding ferroalloys into the liquid metal simultaneously removing gases to the gas cleaning system through its port at its top. The bell-shaped snorkel consists of two parts. The upper part has an inside liner, and the lower part is lined on both side with high-alumina castable reinforced with 2% stainless steel needles. Both the parts are coupled with a flange bolt system. These flanges were found to get buckled during operation, and the gap was generating between them. This problem was chronic since its. It was expected to give a life of 80 heats, but it was failing within 45-50 heats. After every 25-30 heats, it had to be repaired by changing and/or tightening its nuts and bolts. Visual observation, microstructural analysis through optical microscopes and SEM, hardness measurement and thermal strain calculation were carried out to find out the root cause of this problem. The calculated thermal strain was compared with actual thermal strain; comparison of the two revealed that thermal strain was responsible for buckling. Finite element analysis (FEA) was carried out to reaffirm the effect temperature on the flanges. FEA was also used in the modification in the design of snorkel flange to accommodate thermal strain. Thermal insulation was also recommended which increased its life from 45 heats to 65 heats, impacting business process positively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CAS%20OB%20process" title="CAS OB process">CAS OB process</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=snorkel" title=" snorkel"> snorkel</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20strain" title=" thermal strain"> thermal strain</a> </p> <a href="https://publications.waset.org/abstracts/107211/dealing-with-buckling-effect-in-snorkel-by-finite-element-analysis-a-life-enhancement-approach-in-cas-ob-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107211.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30170</span> An Approximate Lateral-Torsional Buckling Mode Function for Cantilever I-Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Ozbasaran">H. Ozbasaran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lateral torsional buckling is a global stability loss which should be considered in the design of slender structural members under flexure about their strong axis. It is possible to compute the load which causes lateral torsional buckling of a beam by finite element analysis, however, closed form equations are needed in engineering practice. Such equations can be obtained by using energy method. Unfortunately, this method has a vital drawback. In lateral torsional buckling applications of energy method, a proper function for the critical lateral torsional buckling mode should be chosen which can be thought as the variation of twisting angle along the buckled beam. The accuracy of the results depends on how close is the chosen function to the exact mode. Since critical lateral torsional buckling mode of the cantilever I-beams varies due to material properties, section properties, and loading case, the hardest step is to determine a proper mode function. This paper presents an approximate function for critical lateral torsional buckling mode of doubly symmetric cantilever I-beams. Coefficient matrices are calculated for the concentrated load at the free end, uniformly distributed load and constant moment along the beam cases. Critical lateral torsional buckling modes obtained by presented function and exact solutions are compared. It is found that the modes obtained by presented function coincide with differential equation solutions for considered loading cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling%20mode" title="buckling mode">buckling mode</a>, <a href="https://publications.waset.org/abstracts/search?q=cantilever" title=" cantilever"> cantilever</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral-torsional%20buckling" title=" lateral-torsional buckling"> lateral-torsional buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=I-beam" title=" I-beam"> I-beam</a> </p> <a href="https://publications.waset.org/abstracts/34077/an-approximate-lateral-torsional-buckling-mode-function-for-cantilever-i-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34077.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">368</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30169</span> Flange/Web Distortional Buckling of Cold-Formed Steel Beams with Web Holes under Pure Bending</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nan-Ting%20Yu">Nan-Ting Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Boksun%20Kim"> Boksun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Long-Yuan%20Li"> Long-Yuan Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cold-formed steel beams with web holes are widely used as the load-carrying members in structural engineering. The perforations can release the space of the building and let the pipes go through. However, the perforated cold-formed steel (PCFS) beams may fail by distortional buckling more easily than beams with plain web; this is because the rotational stiffness from the web decreases. It is well known that the distortional buckling can be described as the buckling of the compressed flange-lip system. In fact, near the ultimate failure, the flange/web corner would move laterally, which indicates the bending of the web should be taken account. The purpose of this study is to give a specific solution for the critical stress of flange/web distortional buckling of PCFS beams. The new model is deduced based on classical energy method, and the deflection of the web is represented by the shape function of the plane beam element. The finite element analyses have been performed to validate the accuracy of the proposed model. The comparison of the critical stress calculated from Hancock's model, FEA, and present model, shows that the present model can provide a splendid prediction for the flange/web distortional buckling of PCFS beams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold-formed%20steel" title="cold-formed steel">cold-formed steel</a>, <a href="https://publications.waset.org/abstracts/search?q=beams" title=" beams"> beams</a>, <a href="https://publications.waset.org/abstracts/search?q=perforations" title=" perforations"> perforations</a>, <a href="https://publications.waset.org/abstracts/search?q=flange-web%20distortional%20buckling" title=" flange-web distortional buckling"> flange-web distortional buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a> </p> <a href="https://publications.waset.org/abstracts/122660/flangeweb-distortional-buckling-of-cold-formed-steel-beams-with-web-holes-under-pure-bending" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122660.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30168</span> Thermal Postbuckling of First Order Shear Deformable Functionally Graded Plates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merbouha%20Barka">Merbouha Barka</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20H.%20Benrahou"> K.

Failure mode under in-plane compression is investigated by means of numerical analysis with ABAQUS platform. Parameters considered in this study are contact length and both the type of foam for core and the variation of its Young's Modulus under the thermal influence. Variation of temperature is considered in static cases and only applied to core. Indeed, it is shown that the effect of temperature on the panel system mechanical properties is significance. Moreover, the variations of temperature result in the decrements of the system strength. This is due to the polymeric nature of this material. Additionally, the contact length also displays the effect on performance of infill panel. Their significance factors are based on type of polymer for core. Hence, by comparing difference type of core material, the variation can be reducing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling" title="buckling">buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20length" title=" contact length"> contact length</a>, <a href="https://publications.waset.org/abstracts/search?q=foam%20core" title=" foam core"> foam core</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20dependent" title=" temperature dependent"> temperature dependent</a> </p> <a href="https://publications.waset.org/abstracts/41671/buckling-resistance-of-gfrp-sandwich-infill-panels-with-different-cores-under-increased-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41671.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30166</span> Euler-Bernoulli’s Approach for Buckling Analysis of Thick Rectangular Plates Using Alternative I Refined Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Owus%20Mathias%20Ibearugbulem">Owus Mathias Ibearugbulem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study presents Euler-Bernoulli’s approach for buckling analysis of thick rectangular plates using alternative I refined theory. No earlier study, to the best knowledge of the author, based on the literature available to this research, applied Euler-Bernoulli’s approach in the alternative I refined theory for buckling analysis of thick rectangular plates. In this study, basic kinematics and constitutive relations for thick rectangular plates are employed in the differential equations of equilibrium of stresses in a deformable elemental body to obtain alternative I governing differential equations of thick rectangular plates and the corresponding compatibility equations. Solving these equations resulted in a general deflection function of a thick rectangular plate. Using this function and satisfying the boundary conditions of three plates, their peculiar deflection functions are obtained. Going further, the study determined the non-dimensional critical buckling loads of the six plates. Values of the non-dimensional critical buckling load from the present study are compared with those from a three-dimensional buckling analysis of a thick plate. The highest percentage difference recorded for the plates: all edges simply supported (ssss), all edges clamped (cccc) and adjacent edges clamped with the other edges simply supported (ccss) are 3.31%, 5.57% and 3.38% respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Euler-Bernoulli" title="Euler-Bernoulli">Euler-Bernoulli</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20I" title=" alternative I"> alternative I</a>, <a href="https://publications.waset.org/abstracts/search?q=kinematics" title=" kinematics"> kinematics</a>, <a href="https://publications.waset.org/abstracts/search?q=constitutive%20relation" title=" constitutive relation"> constitutive relation</a>, <a href="https://publications.waset.org/abstracts/search?q=governing%20differential%20equation" title=" governing differential equation"> governing differential equation</a>, <a href="https://publications.waset.org/abstracts/search?q=compatibility%20equation" title=" compatibility equation"> compatibility equation</a>, <a href="https://publications.waset.org/abstracts/search?q=thick%20plate" title=" thick plate"> thick plate</a> </p> <a href="https://publications.waset.org/abstracts/188996/euler-bernoullis-approach-for-buckling-analysis-of-thick-rectangular-plates-using-alternative-i-refined-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188996.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">30</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30165</span> Effect of Corrosion on the Shear Buckling Strength</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Myoung-Jin%20Lee">Myoung-Jin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Jin%20Lee"> Sung-Jin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Kon%20Park"> Young-Kon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin-Wook%20Kim"> Jin-Wook Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo-Kyoung%20Kim"> Bo-Kyoung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Song-Hun%20Chong"> Song-Hun Chong</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun-Ii%20Kim"> Sun-Ii Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ability to resist the shear strength arises mainly from the web panel of steel girders and as such, the shear buckling strength of these girders has been extensively investigated. For example, Blaser’s reported that when buckling occurs, the tension field has an effect after the buckling strength of the steel is reached. The findings of these studies have been applied by AASHTO, AISC, and to the European Code that provides guidelines for designs aimed at preventing shear buckling. Steel girders are susceptible to corrosion resulting from exposure to natural elements such as rainfall, humidity, and temperature. This corrosion leads to a reduction in the size of the web panel section, thereby resulting in a decrease in the shear strength. The decrease in the panel section has a significant effect on the maintenance section of the bridge. However, in most conventional designs, the influence of corrosion is overlooked during the calculation of the shear buckling strength and hence over-design is common. Therefore, in this study, a steel girder with an A/D of 1:1, as well as a 6-mm-, 16-mm-, and 12-mm-thick web panel, flange, and intermediate reinforcing material, respectively, were used. The total length was set to that (3200 mm) of the default model. The effect of corrosion shear buckling was investigated by determining the volume amount of corrosion, shape of the erosion patterns, and the angular change in the tensile field of the shear buckling strength. This study provides the basic data that will enable designs that incorporate values closer (than those used in most conventional designs) to the actual shear buckling strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20buckling%20strength" title=" shear buckling strength"> shear buckling strength</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20girder" title=" steel girder"> steel girder</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strength" title=" shear strength"> shear strength</a> </p> <a href="https://publications.waset.org/abstracts/46131/effect-of-corrosion-on-the-shear-buckling-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46131.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30164</span> Buckling Analysis of Laminated Composite Plates with Central Holes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pratyasha%20Patnaik">Pratyasha Patnaik</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20V.%20Asha"> A.

These have an application in aircrafts, railway coaches, bridges etc. because they are easy to handle, have got improved properties and the cost of their fabrication is low. But their failure can lead to catastrophic disasters. And generally, the failure of these structures is due to the combined effect of excessive stresses on it and buckling. Hence, the buckling behavior of these kinds of plates should be analyzed properly. Holes are provided either at the center or elsewhere in the laminar plates for the purpose of pipes for electric cables or other purposes. Due to the presence of holes in the plates, the stress concentration is near to the holes and the stiffness of the plates is reduced. In this study, the effect of a cut-out, its shape, different boundary conditions, length/thickness ratio, stacking sequence, and ply orientation has been studied. The analysis was carried out with laminated composite plates with circular, square and triangular cut-outs. Results show the effect of different cut-out shapes, boundary conditions, the orientation of layers and length/thickness ratio of the buckling load <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling" title="buckling">buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20plates" title=" composite plates"> composite plates</a>, <a href="https://publications.waset.org/abstracts/search?q=cut-out" title=" cut-out"> cut-out</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress "> stress </a> </p> <a href="https://publications.waset.org/abstracts/47770/buckling-analysis-of-laminated-composite-plates-with-central-holes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47770.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30163</span> Buckling Analysis of Composite Shells under Compression and Torsional Loads: Numerical and Analytical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCne%C5%9F%20Ayd%C4%B1n">Güneş Aydın</a>, <a href="https://publications.waset.org/abstracts/search?q=Razi%20Kalantari%20Osgouei"> Razi Kalantari Osgouei</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Emre%20%C3%96zt%C3%BCrk"> Murat Emre Öztürk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Partovi%20Meran"> Ahmad Partovi Meran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ekrem%20T%C3%BCfek%C3%A7i"> Ekrem Tüfekçi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Advanced lightweight laminated composite shells are increasingly being used in all types of modern structures, for enhancing their structural efficiency and performance.

In many instances, the failure of the pile founded structures in liquefiable soils had been observed even in many recent earthquakes. Recent centrifuge and shake table experiments on two layered soil system have credibly shown that failure of pile foundation can occur because of buckling, as the pile behaves as an unsupported slender structural element once the surrounding soil liquefies. However the buckling capacity depends on largely on the depth of soil liquefied and its residual strength. Hence it is essential to check the pile against the possible buckling failure. Beam on non-linear Winkler Foundation is one of the efficient method to model the pile-soil behavior in liquefiable soil. The pile-soil interaction is modelled through p-y springs, different author have proposed different types of p-y curves for the liquefiable soil. In the present paper the influence two such p-y curves on the buckling capacity of pile foundation is studied considering initial geometric and non-linear behavior of pile foundation. The proposed method is validated against experimental results. Significant difference in the buckling capacity is observed for the two p-y curves used in the analysis. A parametric study is conducted to understand the influence of pile diameter, pile flexural rigidity, different initial geometric imperfections, and different soil relative densities on buckling capacity of pile foundation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pile%20foundation" title="Pile foundation ">Pile foundation </a>, <a href="https://publications.waset.org/abstracts/search?q=Liquefaction" title=" Liquefaction"> Liquefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Buckling%20load" title=" Buckling load"> Buckling load</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20py%20curve" title=" non-linear py curve"> non-linear py curve</a>, <a href="https://publications.waset.org/abstracts/search?q=Opensees" title=" Opensees"> Opensees</a> </p> <a href="https://publications.waset.org/abstracts/130562/influence-of-p-y-curves-on-buckling-capacity-of-pile-foundation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130562.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30161</span> Seismic Behavior of Short Core Buckling Restrained Braces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nader%20Hoveidae">Nader Hoveidae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the seismic behavior of a new type of buckling restrained braces (BRBs) called "Short Core BRBs" in which a shorter core segment is used as an energy dissipating part and an elastic part is serially connected to the core. It seems that a short core BRB is easy to be fabricated, inspected and replaced after a severe earthquake. In addition, the energy dissipating capacity in a short core BRB is higher because of larger core strains. However, higher core strain demands result in high potential of low-cycle fatigue fracture. In this paper, a strategy is proposed to estimate the minimum core length in a short core BRBs. The seismic behavior of short core buckling restrained brace is experimentally examined. The results revealed that the short core buckling restrained brace is able to sustain large inelastic strains without any significant instability or strength degradation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=short%20core" title="short core">short core</a>, <a href="https://publications.waset.org/abstracts/search?q=Buckling%20Restrained%20Brace" title=" Buckling Restrained Brace"> Buckling Restrained Brace</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20test" title=" cyclic test"> cyclic test</a> </p> <a href="https://publications.waset.org/abstracts/37090/seismic-behavior-of-short-core-buckling-restrained-braces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37090.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">360</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30160</span> Numerical Study for Compressive Strength of Basalt Composite Sandwich Infill Panel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Viriyavudh%20Sim">Viriyavudh Sim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung%20Kyu%20Choi"> Jung Kyu Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Ju%20Kwak"> Yong Ju Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Oh%20Hyeon%20Jeon"> Oh Hyeon Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Woo%20Young%20Jung"> Woo Young Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we investigated the buckling performance of basalt fiber reinforced polymer (BFRP) sandwich infill panels.

For the experimental study, four different sections of columns were tested to investigate effect of stiffening and width-to-thickness ratio on buckling behavior. For each of the section, three lengths of 230, 950 and 1900 mm. were studied representing short, intermediate long and long columns, respectively. Then, nonlinear finite element analyses of the tested columns were performed. The comparisons in terms of load-deformation response and buckling mode show good agreement and hence the FEM models were validated. Parametric study of stiffening element and thickness of 1.0, 1.15, 1.2, 1.5, 1.6 and 2.0 mm. were analyzed. The test results showed that stiffening effect pays a large contribution to prevent distortional mode. The increase in wall thickness enhanced buckling stress beyond the yielding strength in short and intermediate columns, but not for the long columns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling%20behavior" title="buckling behavior">buckling behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=irregular%20section" title=" irregular section"> irregular section</a>, <a href="https://publications.waset.org/abstracts/search?q=cold-formed%20steel" title=" cold-formed steel"> cold-formed steel</a>, <a href="https://publications.waset.org/abstracts/search?q=concentric%20loading" title=" concentric loading"> concentric loading</a> </p> <a href="https://publications.waset.org/abstracts/28181/buckling-performance-of-irregular-section-cold-formed-steel-columns-under-axially-concentric-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28181.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30158</span> On the Evaluation of Critical Lateral-Torsional Buckling Loads of Monosymmetric Beam-Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Yilmaz">T.

Lateral torsional buckling is one of the major failure modes in which beam-columns that are bent about its strong axis may buckle out of the plane by deflecting laterally and twisting. This study presents a compact closed-form equation that it can be used for calculating critical lateral torsional-buckling load of beam-columns with monosymmetric sections in the presence of a known axial load. Lateral-torsional buckling behavior of beam-columns subjected to constant axial force and various transverse load cases are investigated by using Ritz method in order to establish proposed equation. Lateral-torsional buckling loads calculated by presented formula are compared to finite element model results. ABAQUS software is utilized to generate finite element models of beam-columns. It is found out that lateral-torsional buckling load of beam-columns with monosymmetric sections can be determined by proposed equation and can be safely used in design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lateral-torsional%20buckling" title="lateral-torsional buckling">lateral-torsional buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=beam-column" title=" beam-column"> beam-column</a>, <a href="https://publications.waset.org/abstracts/search?q=monosymmetric%20section" title=" monosymmetric section"> monosymmetric section</a> </p> <a href="https://publications.waset.org/abstracts/51595/on-the-evaluation-of-critical-lateral-torsional-buckling-loads-of-monosymmetric-beam-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51595.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">324</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30157</span> Analysis of Thermal Effect on Functionally Graded Micro-Beam via Mixed Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cagri%20Mollamahmutoglu">Cagri Mollamahmutoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mercan"> Ali Mercan</a>, <a href="https://publications.waset.org/abstracts/search?q=Aykut%20Levent"> Aykut Levent</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies concerning the microstructures are becoming more important as the utilization of various micro-electro mechanical systems (MEMS) are increasing. Thus in recent years, thermal buckling and vibration analysis of microstructures have been subject to many investigations that are utilizing different numerical methods. In this study, thermal effects on mechanical response of a functionally graded (FG) Timoshenko micro-beam are presented in the framework of a mixed finite element formulation. Size effects are taken into consideration via modified couple stress theory. The mixed formulation is based on a function which in turn is derived via Gateaux Differential scientifically. After the resolution of all field equations of the beam, a potential operator is carefully constructed. Then this operator is used for the manufacturing of the functional. Usual procedures of finite element approximation are utilized for the derivation of the mixed finite element equations once the potential is obtained. Resulting finite element formulation allows usage of C₀ type simple linear shape functions and avoids shear-locking phenomena, which is a common shortcoming of the displacement-based formulations of moderately thick beams. The developed numerical scheme is used to obtain the effects of thermal loads on the static bending, free vibration and buckling of FG Timoshenko micro-beams for different power-law parameters, aspect ratios and boundary conditions. The versatility of the mixed formulation is presented over other numerical methods such as generalized differential quadrature method (GDQM). Another attractive property of the formulation is that it allows direct calculation of the contribution of micro effects on the overall mechanical response. <p
