Large-scale models or full scale seismic tests can be carried out by using this method. CFST-RC columns are used in civil engineering structures because of their better seismic performance. A CFST-RC column is composed of four CFST limbs which are connected with RC web in longitudinal direction and with steel tube in transverse direction. For this study, a CFST-RC pier is tested under Four different earthquake time histories having scaled PGA of 0.05g. From the experiment acceleration, velocity, displacement and load time histories are observed. The dynamic magnification factors for acceleration due to Elcentro, Chi-Chi, Imperial Valley and Kobe ground motions are observed as 15, 12, 17 and 14 respectively. The natural frequency of the pier is found to be 1.40 Hz. The result shows that this type of pier has excellent static and earthquake resistant properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge%20pier" title="bridge pier">bridge pier</a>, <a href="https://publications.waset.org/abstracts/search?q=CFST-RC%20pier" title=" CFST-RC pier"> CFST-RC pier</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudo%20dynamic%20test" title=" pseudo dynamic test"> pseudo dynamic test</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20history" title=" time history"> time history</a> </p> <a href="https://publications.waset.org/abstracts/81610/seismic-behavior-of-concrete-filled-steel-tube-reinforced-concrete-column" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81610.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">185</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">10</span> Comparative Study on Structural Behaviour of Circular Hollow Steel Tubular, Concrete Filled Steel Tubular, and Reinforced Cement Concrete Stub Columns under Pure Axial Compression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niladri%20Roy">Niladri Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Longshithung%20Patton"> M.

These results are further compared with the respective experimental results. FE software package ABAQUS 6.14 has been used for further parametric studies where a total of 108 FE models were modelled. The diameters of the HST, CFST, and RCC stub columns are kept as 100, 140, 180, and 220, with length to diameter ratio fixed at 3 to avoid end effects and flexural failure. To keep the same percentage of steel (by volume), the thicknesses of steel tubes in HST and CFST columns were varied in response to the change in diameter of the main reinforcement bar in RCC columns. M25 grade of concrete was used throughout. The objective is to compare the structural behaviour of HST, CFST, and RCC stub columns on the basis of their axial compressive load carrying capacity and failure modes. The studies show that filling the circular HST columns with concrete increases the Pu of the CCFST columns by 2.97 times. It was also observed that the Pu (HST) is about 0.72 times Pu (RCC) on average, and the Pu (CFST) is about 2.08 times Pu (RCC) on average. After the analysis and comparison, it has been proved that CFST has much more load carrying capacity than HST and RCC and also provides the same strength at a very less sectional size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HST%20columns" title="HST columns">HST columns</a>, <a href="https://publications.waset.org/abstracts/search?q=stub%20columns" title=" stub columns"> stub columns</a>, <a href="https://publications.waset.org/abstracts/search?q=CFST%20columns" title=" CFST columns"> CFST columns</a>, <a href="https://publications.waset.org/abstracts/search?q=RCC%20columns" title=" RCC columns"> RCC columns</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=ABAQUS" title=" ABAQUS"> ABAQUS</a> </p> <a href="https://publications.waset.org/abstracts/154745/comparative-study-on-structural-behaviour-of-circular-hollow-steel-tubular-concrete-filled-steel-tubular-and-reinforced-cement-concrete-stub-columns-under-pure-axial-compression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154745.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">100</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">9</span> Analytical Study of Flexural Strength of Concrete-Filled Steel Tube Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maru%20R.">Maru R.</a>, <a href="https://publications.waset.org/abstracts/search?q=Singh%20V.%20P."> Singh V. P.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, analytical study of the flexural strength of Concrete Filled Steel Tube (CFST) beams is carried out based on wide-range finite element models to obtain the better perspective for flexural strength achievement with the use of ABAQUS finite element program. This work adopts concrete damaged plasticity model to get the actual simulation of CFST under bending. To get the decent interaction between concrete and steel, normal and tangential surface interaction provided by ABAQUS is used with hard contact for normal surface interaction and for 0.65 friction coefficient for tangential surface interactions. In this study, rectangular and square CFST beam model cross-sections are adopted with its limits pertained to Eurocode specifications. To get the visualization for flexural strength of CFST beams, total of 74 rectangular CFST beams and 86 square CFST beams are used with four-point bending test setup and the length of the beam model as 1000mm. The grades of concrete and grades of steel are used as 30 MPa & 35MPa and 235 MPa and 275MPa respectively for both sections to get the confinement factor 0.583 to 2.833, steel ratio of 0.069 to 0.236 and length to depth ratio of 4.167 to 16.667. It was found based on this study that flexural strength of CFST beams falls around strain of 0.012. Eurocode provides the results harmonically with finite elemental results. It was also noted for square sections that reduction of steel ratio is not useful as compared to rectangular section although it increases moment capacity up to certain limits because for square sectional area similar to that of rectangular, it possesses lesser depth than rectangular sections. Also It can be said that effect of increment of grade of concrete can be achieved when thicker steel tube is present. It is observed that there is less increment in moment capacity initially but after D/b ratio 1.2, moment capacity of CFST beam rapidly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ABAQUS" title="ABAQUS">ABAQUS</a>, <a href="https://publications.waset.org/abstracts/search?q=CFST%20beams" title=" CFST beams"> CFST beams</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a>, <a href="https://publications.waset.org/abstracts/search?q=four-point%20bending" title=" four-point bending"> four-point bending</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangular%20and%20square%20sections" title=" rectangular and square sections"> rectangular and square sections</a> </p> <a href="https://publications.waset.org/abstracts/136170/analytical-study-of-flexural-strength-of-concrete-filled-steel-tube-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136170.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">8</span> Collapse Analysis of Planar Composite Frame under Impact Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lian%20Song">Lian Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Shao-Bo%20Kang"> Shao-Bo Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Yang"> Bo Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete filled steel tubular (CFST) structure has been widely used in construction practices due to its superior performances under various loading conditions. However, limited studies are available when this type of structure is subjected to impact or explosive loads. Current methods in relevant design codes are not specific for preventing progressive collapse of CFST structures. Therefore, it is necessary to carry out numerical simulations on CFST structure under impact loads. In this study, finite element analyses are conducted on the mechanical behaviour of composite frames which composed of CFST columns and steel beams subject to impact loading. In the model, CFST columns are simulated using finite element software ABAQUS. The model is verified by test results of solid and hollow CFST columns under lateral impacts, and reasonably good agreement is obtained through comparisons. Thereafter, a multi-scale finite element modelling technique is developed to evaluate the behaviour of a five-storey three-span planar composite frame. Alternate path method and direct simulation method are adopted to perform the dynamic response of the frame when a supporting column is removed suddenly. In the former method, the reason for column removal is not considered and only the remaining frame is simulated, whereas in the latter, a specific impact load is applied to the frame to take account of the column failure induced by vehicle impact. Comparisons are made between these two methods in terms of displacement history and internal force redistribution, and design recommendations are provided for the design of CFST structures under impact loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=planar%20composite%20frame" title="planar composite frame">planar composite frame</a>, <a href="https://publications.waset.org/abstracts/search?q=collapse%20analysis" title=" collapse analysis"> collapse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20loading" title=" impact loading"> impact loading</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20simulation%20method" title=" direct simulation method"> direct simulation method</a>, <a href="https://publications.waset.org/abstracts/search?q=alternate%20path%20method" title=" alternate path method"> alternate path method</a> </p> <a href="https://publications.waset.org/abstracts/66231/collapse-analysis-of-planar-composite-frame-under-impact-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66231.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">518</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">7</span> Comparative Study on Performance of Air-Cooled Condenser (ACC) Steel Platform Structures using SCBF Frames, Spatial Structures and CFST Frames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Gomar">Hassan Gomar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Bagheri"> Shahin Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Keyvan"> Nader Keyvan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mozhdeh%20Shirinzadeh"> Mozhdeh Shirinzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Air-Cooled Condenser (ACC) platform structures are the most complicated and principal structures in power plants and other industrial parts which need to condense the low-pressure steam in the cycle. Providing large spans for this structure has great merit as there would be more space for other subordinate buildings and pertinent equipment. Moreover, applying methods to reduce the overall cost of construction while maintaining its strength against severe seismic loading is of high significance. Tabular spatial structures and composite frames have been widely used in recent years to satisfy the need for higher strength at a reasonable price. In this research program, three different structural systems have been regarded for ACC steel platform using Special Concentrate Braced Frames (SCBF), which is the most common system (first scheme), modular spatial frames (second scheme) and finally, a modified method applying Concrete Filled Steel Tabular (CFST) columns (third scheme). The finite element method using Sap2000 and Etabs software was conducted to investigate the behavior of the structures and make a precise comparison between the models. According to the results, the total weight of the steel structure in the second scheme decreases by 13% compared to the first scheme and applying CFST columns in the third scheme causes a 3% reduction in the total weight of the structure in comparison with the second scheme while all the lateral displacements and P-M interaction ratios are in the admissible limit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ACC" title="ACC">ACC</a>, <a href="https://publications.waset.org/abstracts/search?q=SCBF%20frames" title=" SCBF frames"> SCBF frames</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20structures" title=" spatial structures"> spatial structures</a>, <a href="https://publications.waset.org/abstracts/search?q=CFST%20frames" title=" CFST frames"> CFST frames</a> </p> <a href="https://publications.waset.org/abstracts/146598/comparative-study-on-performance-of-air-cooled-condenser-acc-steel-platform-structures-using-scbf-frames-spatial-structures-and-cfst-frames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146598.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">197</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">6</span> Experimental Studies of Spiral-Confined HSCFST Columns under Uni-Axial Compression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mianheng%20Lai">Mianheng Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Johnny%20Ching%20Ming%20Ho"> Johnny Ching Ming Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoat%20Joen%20Pam"> Hoat Joen Pam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete-filled-steel-tube (CFST) columns are becoming increasingly popular owing to the superior behavior contributed by the composite action. However, this composite action cannot be fully developed because of different dilation properties between steel tube and concrete. During initial compression, there will be de-bonding between the constitutive materials. As a result, the strength, initial stiffness and ductility of CFST columns reduce significantly. To resolve this problem, external confinement in the form of spirals is proposed to improve the interface bonding. In this paper, a total of 14CFST columns with high-strength as well as ultra-high-strength concrete in-filled were fabricated and tested under uni-axial compression. From the experimental results, it can be concluded that the proposed spirals can improve the strength, initial stiffness, ductility and the interface bonding condition of CFST columns by restraining the lateral expansion of steel tube and core concrete. Moreover, the failure modes of confined core concrete change due to the strong confinement provided by spirals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete-filled-steel-tube" title="concrete-filled-steel-tube">concrete-filled-steel-tube</a>, <a href="https://publications.waset.org/abstracts/search?q=confinement" title=" confinement"> confinement</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20mode" title=" failure mode"> failure mode</a>, <a href="https://publications.waset.org/abstracts/search?q=high-strength%20concrete" title=" high-strength concrete"> high-strength concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=spirals" title=" spirals"> spirals</a> </p> <a href="https://publications.waset.org/abstracts/5677/experimental-studies-of-spiral-confined-hscfst-columns-under-uni-axial-compression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5677.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">5</span> A Brief Review of the Axial Capacity of Circular High Strength CFST Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fuat%20Korkut">Fuat Korkut</a>, <a href="https://publications.waset.org/abstracts/search?q=Soner%20Guler"> Soner Guler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concrete filled steel tube (CFST) columns are commonly used in construction applications such as high-rise buildings and bridges owing to its lots of remarkable benefits.

The light gauge steel鈥揷oncrete hybrid structure, including light gauge steel structure and concrete hybrid structure, is a new鈥搕ype steel鈥揷oncrete hybrid structure, which possesses some advantages of light gauge steel structure and concrete hybrid structure. The seismic behavior and loss assessment of three high鈥搑ise buildings with three different concrete hybrid structures were investigated through finite element software, respectively. The three concrete hybrid structures are reinforced concrete column鈥搒teel beam (RC鈥扴) hybrid structure, concrete鈥揻illed steel tube column鈥搒teel beam (CFST鈥扴) hybrid structure, and tubed concrete column鈥搒teel beam (TC鈥扴) hybrid structure. The nonlinear time-history analysis of three high鈥搑ise buildings under 80 earthquakes was carried out. After simulation, it indicated that the seismic performances of three high鈥搑ise buildings were superior. Under extremely rare earthquakes, the maximum inter鈥搒torey drifts of three high鈥搑ise buildings are significantly lower than 1/50. The inter鈥搒torey drift and floor acceleration of high鈥搑ise building with CFST鈥扴 hybrid structure were bigger than those of high鈥搑ise buildings with RC鈥扴 hybrid structure, and smaller than those of high鈥搑ise building with TC鈥扴 hybrid structure. Then, based on the time鈥揾istory analysis results, the post-earthquake repair cost ratio and repair time of three high鈥搑ise buildings were predicted through an economic performance analysis method proposed in FEMA鈥扨58 report. Under frequent earthquakes, basic earthquakes and rare earthquakes, the repair cost ratio and repair time of three high-rise buildings were less than 5% and 15 days, respectively. Under extremely rare earthquakes, the repair cost ratio and repair time of high-rise buildings with TC鈥扴 hybrid structure were the most among three high rise buildings. Due to the advantages of CFST-S hybrid structure, it could be extensively employed in high-rise buildings subjected to earthquake excitations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seismic%20behavior" title="seismic behavior">seismic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=loss%20assessment" title=" loss assessment"> loss assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20gauge%20steel%E2%80%93concrete%20hybrid%20structure" title=" light gauge steel鈥揷oncrete hybrid structure"> light gauge steel鈥揷oncrete hybrid structure</a>, <a href="https://publications.waset.org/abstracts/search?q=high%E2%80%93rise%20building" title=" high鈥搑ise building"> high鈥搑ise building</a>, <a href="https://publications.waset.org/abstracts/search?q=time%E2%80%93history%20analysis" title=" time鈥揾istory analysis"> time鈥揾istory analysis</a> </p> <a href="https://publications.waset.org/abstracts/133887/seismic-behavior-and-loss-assessment-of-high-rise-buildings-with-light-gauge-steel-concrete-hybrid-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133887.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">185</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">2</span> Eccentric Loading of CFDST Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Trevor%20N.%20Haas">Trevor N.

Much attention was allocated to estimate the axial capacity of the traditional column sections to the detriment of other forms of construction. Other forms of column construction such as Concrete Filled Double Skin Tubes received little research attention, and almost no attention when subjected to eccentric loading. This paper investigates the axial capacity of columns when subjected to eccentric loading. The experimental axial capacities are compared to other established theoretical formulae on concentric loading to determine a possible relationship. The study found a good correlation between the reduction in axial capacity for different column lengths and hollow section ratios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CSDST" title="CSDST">CSDST</a>, <a href="https://publications.waset.org/abstracts/search?q=CFST" title=" CFST"> CFST</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20capacity" title=" axial capacity"> axial capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=hollow%20section%20ratios" title=" hollow section ratios"> hollow section ratios</a> </p> <a href="https://publications.waset.org/abstracts/11764/eccentric-loading-of-cfdst-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11764.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">341</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">1</span> A Review of the Axial Capacity of Circular High Strength Concrete-Filled Steel Tube Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20G%C3%BClen">Mustafa G眉len</a>, <a href="https://publications.waset.org/abstracts/search?q=Eylem%20G%C3%BCzel"> Eylem G眉zel</a>, <a href="https://publications.waset.org/abstracts/search?q=Soner%20Guler"> Soner Guler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concrete filled steel tube (CFST) columns are commonly used in construction applications such as high-rise buildings and bridges owing to its lots of remarkable benefits.
