摘要

摘要: 波形钢板剪力墙是一类新型抗侧力体系,在高层建筑结构中获得了广泛应用。为此建立了波形钢板剪力墙的ABAQUS有限元模型,并根据试验结果对建模分析方法的合理性和准确性进行了验证。利用波形钢板剪力墙的有限元模型进行了参数分析,研究了波形参数对波形钢板剪力墙抗剪承载性能的影响,包括波长、波高、倾角等因素与抗剪极限承载力、残余承载力、屈曲后延性等性能指标的相关关系。基于参数分析结果,提出了不同波形参数下波形钢板剪力墙的抗剪承载力设计理论。结果表明:增大波长、波高、倾角可以提升墙体的抗剪极限承载力,其中增加波高效果最为显著;改变波长和波高能够对墙体延性产生一定的影响,但改变倾角几乎不影响墙体延性。所提出的设计公式具有一定的可靠性,可以偏于安全地计算各波形参数墙体的抗剪极限承载力。

Abstract: Corrugated steel plate shear wall (CSPSW) is a novel lateral force resisting system which has been widely applied in high-rise buildings. An ABAQUS finite element (FE) model of CSPSW was established, and the accuracy of the FE method was verified according to existing test results. Based on the FE model, a parameter analysis was conducted and the effect of corrugation parameters on shear capacity of CSPSW was investigated, including the correlation between the wave length, wave height, wave angle and performance indexes, such as ultimate shear capacity, residual bearing capacity and post-buckling ductility of the wall. Based on the results of parametric analysis, a design method for shear capacity of CSPSW with different waveform parameters was proposed. The results showed that the increase of wave length, wave height and wave angle could improve the ultimate shear capacity, and the increase of wave height had the most significant effect. The change of wave length and wave height could had a certain effect on the ductility of wall, but the change of wave angle had negligible effect. The proposed design formula has certain reliability and can be used to safely calculate the ultimate shear bearing capacity of CSPSW.
