钢骨混凝土复合受扭柱抗震性能试验研究

Jianzhu Gangjiegou Jinzhan
为研究含H型钢的钢骨混凝土柱在压弯剪扭复合受力作用下的抗震性能，对7个含H型钢的钢骨混凝土柱和1个钢筋混凝土柱进行拟静力试验，探究了扭弯比、轴压比、配箍率等对试件抗震性能的影响，分析了试件在低周反复加载试验中裂缝产生和发展的规律及破坏特征，讨论了各试件的扭矩-扭率滞回曲线、骨架曲线、耗能能力、延性、刚度退化和损伤分析。结果表明：含H型钢的钢骨混凝土柱在复合受力状态下发生受扭破坏，其扭矩-扭率滞回曲线呈捏拢的S形，相较于普通钢筋混凝土试件，其承载能力和抗震性能更优。增大扭弯比、轴压比 ...

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 ...
