To consider countermeasures for reducing GHG emission, the production estimation of energy intensive materials, such as steel, is essential. About 50% of steel production is exported in Japan, so it is necessary to consider steel production including export. Steel productions from 2005-2050 in Japan were estimated under various global assumptions based on combination of scenarios such as goods trade scenarios and steel making process selection scenarios. Process selection scenarios decide volume of steel production by process (basic oxygen furnace and electric arc furnace) with considering steel consumption projection, supply-demand balance of steel, and scrap surplus. The range of steel production by process was analyzed. Maximum steel production was estimated under the scenario which consumes scrap in domestic steel production at maximum level. In 2035, steel production reaches 149 million ton because of increase in electric arc furnace steel. However, it decreases towards 2050 and amounts to 120 million ton, which is almost same as a current level. Minimum steel production is under the scenario which assumes technology progress in steel making and supply-demand balance consideration in each region. Steel production decreases from base year and is 44 million ton in 2050. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=goods%20trade%20scenario" title="goods trade scenario">goods trade scenario</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20making%20process%20selection%20scenario" title=" steel making process selection scenario"> steel making process selection scenario</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20production" title=" steel production"> steel production</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title=" global warming"> global warming</a> </p> <a href="https://publications.waset.org/abstracts/41704/a-range-of-steel-production-in-japan-towards-2050" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41704.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">383</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">1713</span> Structural Performance of Concrete Beams Reinforced with Steel Plates: Experimental Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mazin%20Mohammed%20S.%20Sarhan">Mazin Mohammed S.

Three reinforced concrete beams with the dimensions of 200 mm x 300 mm x 4000 mm (width x height x length, respectively) were experimentally investigated under flexural loading. The deformed steel bars were used as the main reinforcement for the first beam. A steel plate placed horizontally was used as the main reinforcement for the second beam. The bond between the steel plate and the surrounding concrete was enhanced by using steel bolts (with a diameter of 20 mm and length of 100 mm) welded to the steel plate at a regular distance of 200 mm. A pair of steel plates placed vertically was used as the main reinforcement for the third beam. The bond between the pair steel plates and the surrounding concrete was enhanced by using 4 equal steel angles (with the dimensions of 75 mm x 75 mm and the thickness of 8 mm) for each vertical steel plate. Two steel angles were welded at each end of the steel plate. The outcomes revealed that the bending stiffness of the beams reinforced with steel plates was higher than that reinforced with deformed steel bars. Also, the flexural ductile behavior of the second beam was much higher than the rest beams. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20beam" title="concrete beam">concrete beam</a>, <a href="https://publications.waset.org/abstracts/search?q=deflection" title=" deflection"> deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility" title=" ductility"> ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=plate" title=" plate"> plate</a> </p> <a href="https://publications.waset.org/abstracts/114584/structural-performance-of-concrete-beams-reinforced-with-steel-plates-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114584.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">160</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">1712</span> Ultimate Stress of the Steel Tube in Circular Concrete-Filled Steel Tube Stub Columns Subjected to Axial Compression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siqi%20Lin">Siqi Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yangang%20Zhao"> Yangang Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete-filled steel tube column achieves the excellent performance of high strength, stiffness, and ductility due to the confinement from the steel tube. Well understanding the stress of the steel tube is important to make clear the confinement effect. In this paper, the ultimate stress of the steel tube in circular concrete-filled steel tube columns subjected to axial compression was studied. Experimental tests were conducted to investigate the effects of the parameters, including concrete strength, steel strength, and D/t ratio, on the ultimate stress of the steel tube. The stress of the steel tube was determined by employing the Prandtl-Reuss flow rule associated with isotropic strain hardening. Results indicate that the stress of steel tube was influenced by the parameters. Specimen with higher strength ratio fy/fc and smaller D/t ratio generally leads to a higher utilization efficiency of the steel tube. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete-filled%20steel%20tube" title="concrete-filled steel tube">concrete-filled steel tube</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20compression" title=" axial compression"> axial compression</a>, <a href="https://publications.waset.org/abstracts/search?q=ultimate%20stress" title=" ultimate stress"> ultimate stress</a>, <a href="https://publications.waset.org/abstracts/search?q=utilization%20efficiency" title=" utilization efficiency"> utilization efficiency</a> </p> <a href="https://publications.waset.org/abstracts/71468/ultimate-stress-of-the-steel-tube-in-circular-concrete-filled-steel-tube-stub-columns-subjected-to-axial-compression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71468.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">424</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">1711</span> Architectural Strategies for Designing Durable Steel Structural Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Taghdiri">Alireza Taghdiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Ghanbarzade%20Ghomi"> Sara Ghanbarzade Ghomi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, steel structures are used for not only common buildings but also high-rise construction and wide span covering. The advanced methods of construction as well as the advanced structural connections have a great effect on architecture. However a better use of steel structural systems will be achieved with the deep understanding of steel structures specifications and their substantial advantages. On the other hand, the steel structures face to the different environmental factors such as air flow which cause erosion and corrosion. With the time passing, the amount of these steel mass damages and also the imposed stress will be increased. In other words, the position of erosion in steel structures related to existing stresses indicates that effective environmental conditions will gradually decrease the structural resistance of steel components and result in decreasing the durability of steel components. In this paper, the durability of different steel structural components is evaluated and on the basis of these stress, architectural strategies for designing the system and the components of steel structures is recognized in order to achieve an optimum life cycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=durability" title="durability">durability</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20stress" title=" bending stress"> bending stress</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion%20in%20steel%20structure" title=" erosion in steel structure"> erosion in steel structure</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle" title=" life cycle"> life cycle</a> </p> <a href="https://publications.waset.org/abstracts/18159/architectural-strategies-for-designing-durable-steel-structural-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18159.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">560</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">1710</span> Mechanical and Microstructural Properties of SA 210 Gr.

A total of three beams of 225 mm width, 300 mm height, and 600 mm length were cast and tested. All the beams had the same details of compression reinforcement and stirrups; two plain steel bars of 10 mm diameter (R10) were used for the compression reinforcement, and plain steel bars (R10) at a distance of 80 mm centre to centre were used for the stirrups. The first beam was reinforced with a deformed steel bar while the remaining beams were reinforced with horizontal or vertical chequer steel plates. The results showed no significant difference in the bond force between the beams reinforced with a deformed steel bar or a horizontal steel plate. The beam reinforced with a vertical steel plate considerably presented a bond force higher than the beam reinforced with a horizontal steel plate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond" title="bond">bond</a>, <a href="https://publications.waset.org/abstracts/search?q=pullout" title=" pullout"> pullout</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20concrete" title=" reinforced concrete"> reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20plate" title=" steel plate"> steel plate</a> </p> <a href="https://publications.waset.org/abstracts/114586/bond-strength-of-concrete-beams-reinforced-with-steel-plates-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114586.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">131</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">1705</span> Estimation of World Steel Production by Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reina%20Kawase">Reina Kawase</a> </p> <p class="card-text"><strong>Abstract:</strong></p> World GHG emissions should be reduced 50% by 2050 compared with 1990 level. CO2 emission reduction from steel sector, an energy-intensive sector, is essential. To estimate CO2 emission from steel sector in the world, estimation of steel production is required. The world steel production by process is estimated during the period of 2005-2050. The world is divided into aggregated 35 regions. For a steel making process, two kinds of processes are considered; basic oxygen furnace (BOF) and electric arc furnace (EAF). Steel production by process in each region is decided based on a current production capacity, supply-demand balance of steel and scrap, technology innovation of steel making, steel consumption projection, and goods trade. World steel production under moderate countermeasure scenario in 2050 increases by 1.3 times compared with that in 2012. When domestic scrap recycling is promoted, steel production in developed regions increases about 1.5 times. The share in developed regions changes from 34 %(2012) to about 40%(2050). This is because developed regions are main suppliers of scrap. 48-57% of world steel production is produced by EAF. Under the scenario which thinks much of supply-demand balance of steel, steel production in developing regions increases is 1.4 times and is larger than that in developed regions. The share in developing regions, however, is not so different from current level. The increase in steel production by EAF is the largest under the scenario in which supply-demand balance of steel is an important factor. The share reaches 65%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=global%20steel%20production" title="global steel production">global steel production</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20distribution%20scenario" title=" production distribution scenario"> production distribution scenario</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20making%20process" title=" steel making process"> steel making process</a>, <a href="https://publications.waset.org/abstracts/search?q=supply-demand%20balance" title=" supply-demand balance"> supply-demand balance</a> </p> <a href="https://publications.waset.org/abstracts/42610/estimation-of-world-steel-production-by-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42610.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">450</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">1704</span> Effect of Demineralized Water Purity on the Corrosion Behavior of Steel Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20El-Aziz">A.

It was not expected that demineralized water has an aggressive effect on steel alloys, in this study, the effect of water with different purity on steel X52 and stainless steel 316L was investigated. Weight loss and electrochemical measurements were employed to measure the corrosion behavior. Samples were microscopically investigated after test. It was observed that the higher the water purity the more reactive it is. Comparative analysis of the potentiodynamic curves for different water purity showed the aggressiveness of the demineralised water (conductivity of 0.05 microSiemens per cm) over the distilled water. Whereas, the corrosion rates of stainless steel 858 and 623 nm/y for demi and distilled water respectively. On the other hand, the corrosion rates of carbon steel x52 were estimated about 4.8 and 3.6 µm/y for demi and distilled water, respectively. Open circuit potential (OCP) recorded more positive potentials in case of stainless steel than carbon steel in different water purities. Generally, stainless steel illustrated high pitting resistance than carbon steel alloy, the surface film was investigated by scanning electron microscopy (SEM) and analyzed by energy dispersive X-ray spectroscopy (EDX). This behavior was explained based on that demi and distilled water might be considered as ‘hungry water’ in which it wants to be in equilibrium and will pull ions out of the surrounding metals trying to satisfy its ‘hunger’. <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=demineralized%20water" title=" demineralized water"> demineralized water</a>, <a href="https://publications.waset.org/abstracts/search?q=distilled%20water" title=" distilled water"> distilled water</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20alloys" title=" steel alloys"> steel alloys</a> </p> <a href="https://publications.waset.org/abstracts/50480/effect-of-demineralized-water-purity-on-the-corrosion-behavior-of-steel-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50480.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">813</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">1703</span> Calculating Quantity of Steel Bar Placed in Mesh Form in a Circular Slab or Dome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karam%20Chand%20Gupta">Karam Chand Gupta </a> </p> <p class="card-text"><strong>Abstract:</strong></p> When steel reinforcement is placed in mesh form in circular concrete slab at base or domes at top in case of over head service reservoir or any other structure, it is difficult to estimate/measure the total quantity of steel that would be needed or placed.

Concentric steel bracing provide an excellent approach for strengthening and stiffening steel buildings. Using these braces the designer can hardly adjust the stiffness together with ductility as needed because of buckling of braces in compression. In this study the use of SMA bracing and steel bracing (Mega) utilized in steel frames are investigated. The effectiveness of these two systems in rehabilitating a mid-rise eight-storey steel frames were examined using time-history nonlinear analysis utilizing Seismo-Struct software. Results show that both systems improve the strength and stiffness of the original structure but due to excellent behavior of SMA in nonlinear phase and under compressive forces this system shows much better performance than the rehabilitation system of Mega bracing. <p class="card-text"><strong>Keywords:</strong> <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=seismic%20response" title=" seismic response"> seismic response</a>, <a href="https://publications.waset.org/abstracts/search?q=shapes%20memory%20alloy" title=" shapes memory alloy"> shapes memory alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20frame" title=" steel frame"> steel frame</a>, <a href="https://publications.waset.org/abstracts/search?q=mega%20bracing" title=" mega bracing"> mega bracing</a> </p> <a href="https://publications.waset.org/abstracts/4180/seismic-response-of-braced-steel-frames-with-shape-memory-alloy-and-mega-bracing-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4180.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">325</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">1701</span> Behaviour of Hybrid Steel Fibre Reinforced High Strength Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emdad%20K.%20Z.%20Balanji">Emdad K.

There are huge efforts and study has been done so far on phase transformations, due to so many steel grades available commercially the phase development in steel has different consequences. In the present work an effort has been made to study the effect of heating rate on microstructural features of cold heading quality steel. The SEM, optical microscopy, and heat treatment techniques have been applied to observe the microstructural features in the experimental steel. It was observed that heating rate has the strong influence on phase transformation of CHQ steel under investigation. Heating rate increases the austenite formation kinetics with respect to holding time, and this austenite has been transformed to martensite upon cooling. Heating rate also plays a vital role on nucleation sites of austenite formation in the experimental steel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CHQ%20steel" title="CHQ steel">CHQ steel</a>, <a href="https://publications.waset.org/abstracts/search?q=austenite%20formation" title=" austenite formation"> austenite formation</a>, <a href="https://publications.waset.org/abstracts/search?q=heating%20rate" title=" heating rate"> heating rate</a>, <a href="https://publications.waset.org/abstracts/search?q=nucleation" title=" nucleation"> nucleation</a> </p> <a href="https://publications.waset.org/abstracts/66565/effect-of-heating-rate-on-microstructural-developments-in-cold-heading-quality-steel-used-for-automotive-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66565.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">410</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">1699</span> Emissivity Analysis of Hot-Dip Galvanized Steel in Fire </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christian%20Gaigl">Christian Gaigl</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Mensinger"> Martin Mensinger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Once a fire resistance rating is necessary, it has to be proofed that the load bearing behavior of a steel construction under the exposure of fire still fits the static demands. High costs of passive fire protection, which satisfies the requirements, frequently result in a concrete solution. To optimize these expenses, one method is to determine the critical temperature according to the Eurocode DIN EN 1993-1-2. For this purpose, positive effects of hot-dip galvanized surface layers on the temperature development of steel members in the accidental situation of fire exposure has been investigated. The test results show a significant better heating behavior of hot-dip galvanized steel components compared to normal steel specimen. This leads in many cases to a R30 (30 minutes of ISO-fire) fire protection requirement of unprotected steel members and therefore to an economic added value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20resistance" title="fire resistance">fire resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=hot-dip%20galvanizing" title=" hot-dip galvanizing"> hot-dip galvanizing</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20constructions" title=" steel constructions"> steel constructions</a>, <a href="https://publications.waset.org/abstracts/search?q=R30%20requirement" title=" R30 requirement"> R30 requirement</a>, <a href="https://publications.waset.org/abstracts/search?q=emissivity" title=" emissivity"> emissivity</a> </p> <a href="https://publications.waset.org/abstracts/94148/emissivity-analysis-of-hot-dip-galvanized-steel-in-fire" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94148.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">261</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">1698</span> Behavior of Double Skin Circular Tubular Steel-Concrete-Composite Column</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Usha%20Sivasankaran">Usha Sivasankaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Seetha%20Raman"> Seetha Raman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Experimental work on Double skin Concrete Filled tubes (DSCFT) are a variation of CFT (Concrete- filled steel tubular) with a hollow core formed by two concentric steel tubes in – filled with concrete.

Sarkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In steel construction, there are two families of structural members. One is hot rolled steel and another is cold formed steel. Cold formed steel section includes steel sheet, strip, plate or flat bar. Cold formed steel section is manufactured in roll forming machine by press brake or bending operation. Cold formed steel (CFS), also known as Light Gauge Steel (LGS). As cold formed steel is a sustainable material, it is widely used in green building. Cold formed steel can be recycled and reused with no degradation in structural properties. Cold formed steel structures can earn credits for green building ratings such as LEED and similar programs. Cold formed steel construction satisfies international demand for better, more efficient and affordable buildings. Cold formed steel sections are used in building, car body, railway coach, various types of equipment, storage rack, grain bin, highway product, transmission tower, transmission pole, drainage facility, bridge construction etc. Various shapes of cold formed steel sections are available, such as C section, Z section, I section, T section, angle section, hat section, box section, square hollow section (SHS), rectangular hollow section (RHS), circular hollow section (CHS) etc. In building construction cold formed steel is used as eave strut, purlin, girt, stud, header, floor joist, brace, diaphragm and covering for roof, wall and floor. Cold formed steel has high strength to weight ratio and high stiffness. Cold formed steel is non shrinking and non creeping at ambient temperature, it is termite proof and rot proof. CFS is durable, dimensionally stable and non combustible material. CFS is economical in transportation and handling. At present days cold formed steel becomes a competitive building material. In this paper all these applications related present research work are described and how the CFS can be used as blast resistant structural system that is examined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20form%20steel%20sections" title="cold form steel sections">cold form steel sections</a>, <a href="https://publications.waset.org/abstracts/search?q=applications" title=" applications"> applications</a>, <a href="https://publications.waset.org/abstracts/search?q=present%20research%20review" title=" present research review"> present research review</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20resistant%20design" title=" blast resistant design"> blast resistant design</a> </p> <a href="https://publications.waset.org/abstracts/103415/cold-formed-steel-sections-analysis-design-and-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103415.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">149</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">1694</span> High Strength Steel Thin-Walled Cold-Formed Profiles Manufactured for Automated Rack Supported Warehouses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Natali">A.

Q460GJ structural steel has a nominal yield strength of 460 MPa, which does not decrease significantly with the increase of steel plate thickness like normal structural steel. Thus, Q460GJ structural steel is normally used in medium-walled welded sections. However, research works on the residual stress in GJ steel members are few though it is one of the vital factors that can affect the member and structural behavior. This article aims to investigate the residual stresses in welded I-shaped sections fabricated from Q460GJ structural steel plates by experimental tests. A total of four full scale welded medium-walled I-shaped sections were tested by sectioning method. Both circular curve correction method and straightening measurement method were adopted in this study to obtain the final magnitude and distribution of the longitudinal residual stresses. In addition, this paper also explores the interaction between flanges and webs. And based on the statistical evaluation of the experimental data, a multilayer residual stress model is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Q460GJ%20structural%20steel" title="Q460GJ structural steel">Q460GJ structural steel</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20stresses" title=" residual stresses"> residual stresses</a>, <a href="https://publications.waset.org/abstracts/search?q=sectioning%20method" title=" sectioning method"> sectioning method</a>, <a href="https://publications.waset.org/abstracts/search?q=welded%20medium-walled%20I-shaped%20sections" title=" welded medium-walled I-shaped sections"> welded medium-walled I-shaped sections</a> </p> <a href="https://publications.waset.org/abstracts/66348/experimental-investigation-on-residual-stresses-in-welded-medium-walled-i-shaped-sections-fabricated-from-q460gj-structural-steel-plates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66348.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">317</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">1690</span> The Influence of Basalt and Steel Fibers on the Flexural Behavior of RC Beams </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasmin%20Z.%20Murad">Yasmin Z.

Finite Element (FE) models were developed and validated against experimental data, demonstrating a predictive accuracy of up to 6.5%. The study examined key parameters such as energy dissipation, and failure modes. Results indicate that duplex stainless steel offers the highest strength, with superior energy dissipation but a tendency for brittle failure at maximum strains of 0.149. Austenitic stainless steel demonstrated balanced performance with excellent ductility and energy dissipation, showing a maximum strain of 0.122, making it highly suitable for seismic applications. Ferritic stainless steel, while stronger than carbon steel, exhibited reduced ductility and energy absorption. Carbon steel displayed the lowest performance in terms of energy dissipation and ductility, with significant strain concentrations leading to earlier failure. These findings provide critical insights into optimizing material selection for earthquake-resistant structures, balancing strength, ductility, and energy dissipation under seismic conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Energy%20dissipation" title="Energy dissipation">Energy dissipation</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=H-shaped%20columns" title=" H-shaped columns"> H-shaped columns</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=stainless%20steel%20grades" title=" stainless steel grades"> stainless steel grades</a> </p> <a href="https://publications.waset.org/abstracts/191066/seismic-performance-of-various-grades-of-steel-columns-through-finite-element-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191066.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">24</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">1688</span> Development of a Testing Rig for a Cold Formed-Hot Rolled Steel Hybrid Wall Panel System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mina%20Mortazavi">Mina Mortazavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Ronagh"> Hamid Ronagh</a>, <a href="https://publications.waset.org/abstracts/search?q=Pezhman%20Sharafi"> Pezhman Sharafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The new concept of a cold formed-hot rolled hybrid steel wall panel system is introduced to overcome the deficiency in lateral load resisting capacity of cold-formed steel structures. The hybrid system is composed of a cold-formed steel part laterally connected to hot rolled part. The hot rolled steel part is responsible for carrying the whole lateral load; while the cold formed steel part is only required to transfer the lateral load to the hot rolled part without any local failure. The vertical load is beared by both hot rolled, and cold formed steel part, proportionally. In order to investigate the lateral performance of the proposed system, it should be tested under simultaneous lateral and vertical load. The main concern is to deliver the loads to each part during the test to simulate the real load distribution in the structure.

A total of two groups of beams and one group content five beams, each 750 mm long, 150 mm wide, and 150 mm deep were cast, strengthened and tested till failure under two point loads. One beam was act as a control beam without strengthening and other four beams were strengthened with steel plate at a different arrangement. Other group beams were strengthened with steel plate in shear zone and also strengthened at bottom as first group. The behaviours of the strengthened beams were studied through their load-deflection characteristic upon bending, cracking and mode of failure. The results confirmed that all steel plate arrangements enhanced the strength of the reinforced concrete beam, the positioning of the steel plate affect the moment carrying capacity of the beam. <p
