“…Moreover, concrete-filled steel columns can provide excellent seismic resistant behavior, such as high strength, high ductility, and large energy absorption capacity. As a result, various researches on these types of structures have been conducted in recent years (Gao et al [1]; Ge and Usami [2,3]; Ge et al [4,5]; Morino [6]; Schneider [7]; Susantha et al [8,9]; Hu et al [10]). Figure 1 shows a view of steel box-section bridge pier damaged during Hyogoken-nanbu earthquake near Kobe city in Japan on January 17, 1995.…”

This paper aims to predict the inelastic behavior of thin-walled steel and composite structures, such as hollow and concrete-filled steel columns. For this purpose, a three-dimensional (3D) elasto-plastic finite element analysis methodology has been presented for both thin-walled steel columns with pipe and box-shaped sections, and concrete-filled steel box columns. By comparing with experimental result, it is concluded that the proposed analytical method can give an accurate prediction to the experimental results of both steel and composite structures.Keywords: Steel column; concrete-filled steel column; interface element; cyclic loading; elasto-plastic behavior; buckling mode INTRODUCTIONCantilever steel hollow and concrete-filled columns (CFT) have been widely designed and used as bridge piers in many countries. Such cantilever type bridge piers occupy less space and thus allow the free traffic flow in the roads below the highways. Moreover, concrete-filled steel columns can provide excellent seismic resistant behavior, such as high strength, high ductility, and large energy absorption capacity. Figure 1 shows a view of steel box-section bridge pier damaged during Hyogoken-nanbu earthquake near Kobe city in Japan on January 17, 1995.A clear understanding of inelastic behavior is very important in developing a seismic design methodology for these structures. To this end, the load-displacement curves of the structures play a very important role. To date, fiber model analysis is usually considered as an effective and convenient approach for capacity prediction of structures (Susantha et al. [8,9]). However, this concept without considering local buckling of steel members or interaction between steel-concrete interfaces of composite members needs an additional criterion to determine the ultimate state. On the other hand, three dimensional approaches are very limited because of time-consuming of such analyses and complicated modeling in the case of composite structures. As the rapid development of computers and the spread of use of structural analysis software packages, the 3D analysis will be widely used to better understand inelastic behavior of complicated structures.

“…The advantages of Steel Reinforced Concrete (SRC) constructions over Reinforced Concrete (RC) constructions are: greater ductility, more compact cross-section, reduced creep deformation, and faster concrete casting [1]. Those over Steel construction are: multiple roles of concrete as structural, fireproofing and buckling-restraining elements, higher stiffness, and greater damping.…”

“…Previous studies have shown that CFT structural members have a number of distinct advantages over equivalent steel, reinforced concrete, or steel-reinforced concrete members, especially for seismic resistance. These advantages include high stiffness and strength, large energy absorption and enhanced ductility and stability (Shams and Saadeghvaziri, 1997;Morino, 1998;Uy, 1998;Schneider, 1998;Zhang and Shahrooz, 1999;Liang and Uy, 2000;Bradford et al, 2002). However, since the Poisson's ratio of steel is higher than that of concrete, a separation, caused by differential expansion between the steel tube and the concrete will occur at the early stages of loading (Roeder et al, 1999), which will inevitably delay the activation of the confinement mechanism.…”

Abstract:The mechanical behavior of concrete-filled glass fiber reinforced polymer (GFRP)-steel tube structures under combined seismic loading is investigated in this study. Four same-sized specimens with different GFRP layout modes were tested by a quasi-static test system. Finite element analysis (FEA) was also undertaken and the results were presented. Results of the numerical simulation compared well with those from experimental tests. Parametric analysis was conducted by using the FE models to evaluate the effects of GFRP thickness, axial compression rate, and cross sectional steel ratio. The experimental and numerical results show that the technique of GFRP strengthening is effective in improving the seismic performance of traditional concrete-filled steel tubes, with variations related to different GFRP layout modes.
