两边连接横向波纹钢板剪力墙的力学性能及板形优化

Jianzhu Gangjiegou Jinzhan
波纹钢板剪力墙作为一种新型抗侧力构件，其几何构造在一定程度上起到了加劲作用，避免了板面加劲肋的焊接问题。两边连接横向波纹钢板剪力墙可通过合理设计实现先屈服后屈曲，具有两阶段受力特征，初始抗侧刚度和残余水平承载力较高。采用有限元软件ABAQUS对两边连接横向波纹钢板剪力墙的滞回性能进行了系统的参数研究，给出了具有良好残余水平承载力的板形推荐建议。通过对影响波纹钢板剪力墙力学性能的高厚比、跨高比、波长、波形比和波纹角等几何参数进行分析，发现高厚比和跨高比对波纹钢板剪力墙抗侧性能影响最大 ...

联肢弯剪型钢板剪力墙抗震性能试验研究

Jianzhu Gangjiegou Jinzhan
联肢钢板剪力墙结构是将2片钢板剪力墙通过钢连梁连接形成的抗侧力结构。通过对1榀1/3缩尺的4层联肢弯剪型钢板剪力墙试件进行低周往复加载试验，从滞回曲线、骨架曲线、延性、承载力及刚度退化、耗能能力等方面研究了该结构体系的抗震性能，并且对试件的屈服顺序和变形模式进行了分析。结果表明：联肢钢板剪力墙试件的延性系数达到5.03，承载力退化系数均大于0.96，承载力和刚度退化稳定，等效黏滞阻尼系数达到0.25以上，表明联肢弯剪型钢板剪力墙具有优越的抗震性能。加载过程中，连梁先于墙板发生屈服，墙板先屈曲后屈服 ...
