A shear wall with concrete filled steel tube (CFST) columns and encased steel truss is a new type of shear wall. To determine the seismic performance of the new shear wall, an experiment was carried on a 1/5-scale model. Based on the experimental study, the load-carrying capacity, stiffness, ductility, hysteretic property, energy dissipation and failure phenomena of the model were analyzed. It shows that the seismic performance of a shear wall with CFST columns and encased steel truss has high bearing capacity, stiffness, energy dissipation capacity and good ductility. In addition, a numerical elastic-plastic finite element (FE) analysis of a shear wall with CFST columns and encased steel truss were carried out. The computation results were in good agreement with the test results. FE software, ABAQUS, was used to change the ratio of steel truss to steel tubes and normalized axial force. The influences of different parameters of shear walls were carried out.Keywords: CFST; encased steel truss; shear wall; seismic performance; experimental research IntroductionIn high-rise buildings, the shear wall is usually the main structural component that resists the lateral force. Shear wall with CFST columns is a new type wall developed in recent years (Han and Yang, 2007). Researches have been carried out by some scholars. Kang, T.H. -K et al. (2013) made a careful study of a steel plate shear wall, and found that a properly designed steel plate shear wall would have considerable energy dissipation capacity, ductility, and ultimate strength. Probst, A.D. et al. (2010) studied the composite flexural behavior of full-scale concrete-filled tubes without axial loads. Abolhassan (2001) investigated a steel plate shear wall with CFST columns. During his test, the CFST columns were basically in an elastic state and the specimen showed good ductility and energy dissipation capacity. Qian et al. (2012) conducted a low cyclic loading test on a shear wall with CFST columns. The test results showed that the shear wall had larger load-carrying and deformation capacities relative to the conventional RC wall. Wang et al. (2015) studied the seismic behavior of a lowrise shear wall with CFST frame and embedded steel-

“…Also, the infill concrete leads to change in failure mode of tube at compression zone, from inward buckling to outward buckling, at relatively higher loads [17]. It should be noted that results reported by Probst et al [14] and Prion and Boehme [31] showed that enough confinement for developing the plastic capacity of concrete is not provided, due to local buckling of the tube wall in very thin tubes. Based on the results of previous studies [19,31,33], the axial load of the steel tube that provides confinement for the concrete is unknown.…”

“…Concrete filled steel tubes (CFST) have been used widely in the building and bridge industry [1][2][3][4][5][6][7][8][9][10]. Many studies have shown superior structural behaviour of CFSTs compared to reinforced concrete or steel sections [11][12][13][14][15][16]. Integrated performance of concrete and steel is such that the compressive strength of the concrete core increases because of confining effect of the tube on concrete.…”

The aim of this study is to investigate the effect of active and passive confinement on the flexural behaviour of concrete-filled steel tubes. Three-point flexural test is carried out on twelve confined specimens. The main variable parameters are: tube diameter to thickness ratio (20, 30, and 60), compressive strength of concrete core (15 MPa and 45 MPa), and type of confinement (active or passive). The flexural capacity, energy absorption, flexibility and failure mode of confined specimens, as well as the cracking pattern of concrete core at failure point, are evaluated in this study. The results show that active confinement leads to lower ductile behaviour in specimens with higher strength of concrete core.

“…Concrete is a primary material used in building structures and has contributed significantly to the development of the construction industry [1][2][3]. It became the main axis of the construction industry over a hundred years ago (before the beginning of the First World War), which led to an increased interest in protecting human life and the safety of building structures.…”

Predicting the damage to a concrete panel under impact loading is difficult due to the complexity of the impact mechanism of concrete. Based on the experimental results obtained by various researchers, the energies involved in the impact mechanism are classified into seven categories: Kinetic energy, deformed energy of a projectile, elastic penetration resistance energy of the panel, overall deformed energy of the panel, spalling-resistant energy, tunneling-resistant energy, and scabbing-resistant energy. Using these impact mechanisms and the energy conservation law, a new energy-based penetration depth formula is proposed to predict the penetration depth. This is validated using 402 impact test results, which include those with high-strength concrete, ultra-high-performance concrete (UHPC), or steel fiber-reinforced concrete, those under very high-velocity impact, and those with a very low ratio of target panel thickness to projectile diameter. It is found that the new impact formula predicts the penetration depth quite well.
