摘要

为了研究不同T型加劲肋布置形式对低屈服点薄钢板剪力墙受力性能的影响,采用通用有限元软件ABAQUS建立钢框架—剪力墙非线性数值模型,结合国内外已有的低屈服点钢板剪力墙试验,验证数值方法的有效性。在此基础上,建立几种不同T型肋加劲形式钢板剪力墙模型,对比分析滞回性能、承载性能、退化特性、断裂性能、破坏形态以及耗能能力等,探讨不同T型肋加劲形式钢板剪力墙关键受力性能,并提出相应意见和建议,为工程应用提供参考依据。分析结果表明:设置T型加劲肋能显著改善钢板剪力墙的滞回行为;交叉加劲肋对承载力及刚度提高效果最显著,三竖加劲剪力墙延性最好,十字加劲剪力墙平面外变形最小,三横加劲剪力墙耗能能力最优;使用低屈服点薄钢板剪力墙作为抗侧构件时,需综合考虑承载性能、抗震性能、延性、破坏模式、耗能能力等指标选取合适的加劲形式。
In order to study the behaviors of low yield point steel thin plate shear wall structures with different T-shaped stiffeners,an accurate non-linear finite element model was established with ABAQUS.The numerical method was verified by the existing typical tests of low yield point steel plate shear wall structures.Based on this method,the performances of low yield point steel shear walls with different T-shaped stiffeners were compared in depth,including hysteretic behavior,load-carrying capacity,degradation characteristics,fracture index,failure modes and energy-dissipating capacity.The key issues were discussed to provide a reference for engineering applications.The results show that:T-shaped stiffeners can significantly improve the hysteretic behaviors of steel plate shear walls;CR has the best load-carrying capability and stiffness,VR has the best ductile,SR has the minimal deformation,and HR has the best energy dissipation capacity;The load-carrying capacity,seismic behavior,ductility,failure mode,and energy capacity should be taken into account comprehensively to choose the appropriate stiffened methods of low yield point steel plate shear wall structures.
