摘要
钢板外包混凝土组合剪力墙(C-SPW)是一种新型抗侧力构件,为研究C-SPW在不同高宽比下C-SPW的剪力需求。应用ABAQUS软件,对32个钢板单面外包混凝土C-SPW进行了单调水平荷载下的弹塑性有限元模拟,分析了墙板高宽比、钢板厚度、混凝土板厚、栓钉直径、钢板强度等级对栓钉剪力的影响规律。基于有限元模拟结果,拟合了具有一定安全储备的单面外包混凝土C-SPW栓钉剪力需求计算公式。
Composite steel plate shear wall(C-SPW)is a new type of lateral load resisting system.Due to its significant shear bearing capacity,the lateral stiffness and energy dissipation capacity,the shear wall is increasingly used in high-rise building structures.Previous researches focus mainly on its seismic behavior,few researches pay attention to the shear force demand on headed studs in the C-SPW,and no related studies on C-SPW with different aspect ratios have been found.Based on ABAQUS,the inelastic analysis of 32 C-SPW with concrete encasement on one side of the steel plate under the monotonic lateral loading is conducted.The effects of aspect ratios of wall,steel plate thickness,concrete panel thickness,headed stud diameter and steel plate strength grade on the shear force in headed stud are analyzed.Based on the finite element analysis results,a formula for the shear force demand of headed stud in the design of C-SPW with single sided concrete panel is proposed.
