【摘要】 为研究波形钢板剪力墙及其组合墙在水平荷载作用下的破坏形态、受力性能以及抗剪承载力计算方法,设计了4个波形钢板剪力墙及其组合墙试件,进行了低周往复加载试验,并采用ABAQUS有限元软件对24个波形钢板剪力墙及其组合墙模型进行了模拟分析。研究结果表明:波形钢板剪力墙具有较好的变形能力,波形钢板能有效抑制混凝土裂缝的发展,并与混凝土具有很好的界面粘结力,水平波形钢板剪力墙较易在约束边缘构件底部形成塑性铰;波形钢板剪力墙及其组合墙具有较好的承载能力、延性和耗能能力,且承载力下降缓慢;ABAQUS有限元软件能较好地模拟试验,模拟结果与试验结果吻合较好,有限元计算结果表明:承载力随波形钢板的厚度和波角的增加有少量增加,此外,波形钢板-混凝土组合剪力墙承载力随剪跨比的增加而降低,竖向波形钢板剪力墙的抗侧承载力性能与水平波形钢板剪力墙的基本相同;该文提出的波形钢板剪力墙及其组合墙抗剪承载力计算公式,计算值与试验值吻合良好,可为设计和工程实际参考;H型钢柱对波形钢板-混凝土组合剪力墙的抗剪承载力贡献最小,竖向波形钢板对组合墙剪力分担率大于水平波形钢板的,竖向波形钢板更有利于提升组合墙的承载性能。更多还原

【Abstract】 In order to study the failure pattern and mechanical behavior, and to develop shear bearing capacity calculation methods for corrugated steel plate(CSP) shear wall and CSP-composite wall under horizontal loads, 4 corrugated steel plate shear wall and CSP-composite wall specimens were designed and tested under low-cyclic reverse loading. 24 corrugated steel plate shear wall and CSP-composite wall models were simulated using the ABAQUS finite element software. The results show that the corrugated steel plate shear wall has better deformability, the corrugated steel plate can effectively inhibit the development of concrete cracks, and has good bond stress with concrete. The horizontal corrugated steel plate shear wall is likely to develop a plastic hinge at the bottom of the constraining edge member. Corrugated steel plate shear wall and CSP-composite wall has good load bearing capacity, ductility and energy dissipation capacity, and load bearing capacity decreases slowly.ABAQUS finite element software can simulate the test well, the simulation results have good agreement with the test results, the finite element calculation results demonstrate that the shear bearing capacity increases with the increase of the thickness of the corrugated steel plate and the wave angle. In addition, the load bearing capacity of CSP-composite shear wall decreases with the increasing of the shear-span ratio. The lateral bearing capacity of the vertical corrugated steel plate shear wall is basically the same as that of the horizontal corrugated steel plate shear wall. The calculation formula for the bearing capacity of corrugated steel plate shear wall and CSP-composite wall proposed is in good agreement with the test results, and it can serve as a practical reference for design and engineering application in the future. The H-shaped steel column has slight contribution to the load bearing capacity of the CSP-composite shear wall. The vertical corrugated steel plate has a higher shear share ratio than the horizontal corrugated steel plate, and improves the shear bearing capacity of the CSP-composite wall significantly.更多还原
