钢板单面外包混凝土组合剪力墙栓钉拉力需求

Tensile force demand on headed studs in C-SPW with one side concrete encasement

为了提出钢板单面外包混凝土组合剪力墙中栓钉拉力需求,通过改变栓钉直径、栓钉数量、钢板厚度、外包混凝土板厚度及墙体高宽比等因素,设计了4组共24个算例结构。采用弹塑性有限元分析方法,得到了各组算例栓钉拉力需求与墙板层间侧移角之间的关系,分析了不同设计参数对栓钉拉力需求的影响,提出钢板单面外包混凝土组合剪力墙栓钉拉力需求计算公式。

In order to investigate the tensile force demand on the headed stud in the composite steel plate shear wall (C-SPW) with the reinforced concrete encasement on one side of the steel plate, four groups of C-SPW consisting of 24 specimens are designed by changing factors such as the stud diameter, the number of studs, the steel plate thickness, the concrete panel thickness and the ratio of height and width of the shear wall. By the nonlinear finite element method, the relationship between the stud tension demand and the drift ratio of the interstory of the shear wall was obtained, and the influence of different design parameters on the stud tension demand. Based on the result, available formulas for the demand on the stud tension in the design of C-SPW are proposed.
