摘要
两边连接钢板混凝土组合剪力墙是指仅与框架梁相连的组合剪力墙,该剪力墙能够避免框架柱过早发生破坏,且布置灵活,可以在跨内分段布置,有利于门窗、洞口的开设以及结构刚度的调整.采用有限元方法对两边连接钢板混凝土组合剪力墙的力学性能进行了研究,给出了其抗剪承载力-位移关系的简化曲线,推导了初始刚度计算公式,回归得到承载力计算公式,建立了便于结构体系应用的两边连接钢板混凝土组合剪力墙简化分析模型-双向偏心支撑模型.通过模型计算结果与试验结果进行对比,验证了其正确性,为进一步分析由钢板混凝土组合剪力墙构成的结构体系提供了有效的简化方法.
The steel-concrete composite shear wall system with two-side connections consists of a steel plate wall, two columns and two boundary horizontal floor beams and two reinforced concrete walls attached to both sides of steel shear walls by shear studs or bolts. As the shear walls are not connected to the frame columns, the premature failure, overall buckling or local buckling of the columns can be prevented. In addition, such composite shear walls with relatively small spanto-height ratio can be placed parallel in each bay, which provide open space conveniently. In this paper, the finite element method is employed to study the behavior of composite shear wall with two-side connections. The equations used to calculate the bearing capacity and initial rigidity are proposed. The simplified load-displacement reaction curve and the simplified model （Equivalent eccentric cross-bracing model） are also suggested. Based on the comparison between simplified model results and the experimental results, the simplified model is verified to be the useful method to simulate the composite shear wall in the further research or design of structure systems using composite shear wall with two-side connections.
