- Abstract:
- For a deeper understanding of the shear resistance performance of the steel-concrete-steel composite shear wall, the main influence factors such as the thicknesses of the steel plates and the concrete, the strength grades of the concrete and the span-depth ratios of the composite wall, which have impacts on the shear resistance performance of the composite shear wall, are analyzed by the numerical simulation method. Meanwhile, the simplified calculation formulae of the initial elastic lateral-resisting stiffness and the shear bearing capacity of the composite shear wall are also proposed. The research shows that with the increase in the thicknesses of the steel plates and the concrete and the increase in the strength grades of the concrete, the shear performance of the shear wall improves obviously; the span-depth ratios of the composite wall have a significant effect on the initial elastic lateral-resisting stiffness, but a small effect on the shear bearing capacity. Comparing the results of the simplified calculation formulae with those of the nonlinear finite element method, it is obvious that the presented formulae are reasonable and meet the real force state of the structure. These conclusions can serve as a preliminary design reference for the steel-concrete-steel composite shear wall.
- 为深入了解双层钢板混凝土组合剪力墙的抗剪性能, 采用数值模拟的方法研究了钢板厚度、混凝土厚度、混凝土强度及组合剪力墙的跨高比等主要参数对该组合剪力墙抗剪性能的影响规律, 并提出了该组合剪力墙弹性抗侧刚度及抗剪极限承载力的简化计算公式.研究表明:随着钢板厚度、混凝土厚度、混凝土强度等级的增加, 组合剪力墙的抗剪性能均有较显著的提高;组合剪力墙跨高比的变化对其弹性抗侧刚度影响较大, 而对其抗剪极限承载力的影响并不明显.通过将公式计算结果与有限元计算结果进行对比分析, 发现提出的简化计算公式较合理, 能较好地反映双层钢板混凝土组合剪力墙的实际受力状态.该结论可作为双层钢板混凝土组合剪力墙初步设计的参考建议.
