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.
In order to further understand the shear resistance of double-skinned concrete composite shear walls, numerical simulation methods were used to study the influence of the main parameters such as plate thickness, concrete thickness, concrete strength and span-height ratio of the combined shear wall, Shear performance and the simplified formula of elastic lateral rigidity and ultimate load carrying capacity of the composite shear wall are proposed.The results show that with the increase of the thickness of the steel plate, the thickness of the concrete and the strength of the concrete, the combined shear wall The shear strength of composite shear walls has a significant improvement. The variation of span-height ratio of composite shear walls has a great influence on its elastic lateral stiffness, but its influence on the ultimate bearing capacity is insignificant. Finite element calculation results were compared and found that the proposed simplified calculation formula is more reasonable and can well reflect the actual stress state of double-skinned steel-concrete composite shear wall.This conclusion can be used as the initial design of double-skinned steel-concrete composite shear wall The reference suggestion.
