Abstract The ultra‐high toughness cementitious composite (UHTCC) has the tensile strain‐hardening characteristic and an excellent ability to prevent cracking. To enhance seismic durability performance of conventional buckling‐restrained steel plate shear wall (BRSPSW), UHTCC‐enhanced BRSPSW (UBRSPSW) was proposed in this paper as a new type lateral bearing system. buckling inner is restrained by UHTCC‐normal concrete (NC) functionally graded panels, where panels are composed UHTCC NC layers. In study, experimental numerical research carried out on UBRSPSWs. Six specimens were tested investigate behavior UBRSPSW. Parameters including number stiffeners, thickness UHTCC‐NC material restraining gap between considered test design. Mechanical response failure modes structures under cyclic loads analyzed. obtained hysteretic curves corresponding skeleton indicated that design had performance. Compared (SPSW), load‐bearing capacity UBRSPSW improved 13%, respectively. appearance macrocracks delayed drift angle 1.2%. addition, refined finite element (FE) model developed validated results from experiments. development distribution bending moments extracted based FE method. Then, loading method theoretical for controlling crack width proposed. can provide useful suggestions

A novel concrete-filled corrugated steel tubular (CFCST) column composed of corner bars and plates filled with concrete has been proposed recently. Columns large height-to-width ratios are commonly used in practice, where they often subjected to eccentric compression. However, there is a lack research on their stability behavior under such conditions. This study presented numerical analysis evaluate the performance CFCST columns compression, eccentricity ranging from 0 2.0 between 10 30. The results indicated that N–M interaction curve became less convex as ratio increased. Concrete strength width had greater impact at low ratios, while bar were more influential high ratios. comparison calculation specified AISC 360 GB 50936 showed both them unsuitable estimate Finally, formula was fitted, error basically within 15%, which offered significantly improved accuracy over current design codes.
