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 ...

负弯矩作用下全宽预应力预制桥面板组合梁力学性能研究

横向全宽预应力预制桥面板与分块预制桥面板相比，整体性更好，施工更快捷，在装配式组合梁桥中具有较好的应用前景。负弯矩作用下预制桥面板的湿接缝连接是受力的关键部位，为此对负弯矩作用下的全宽预应力预制桥面板组合梁的力学性能进行研究，明确了横向预应力筋数量、预应力筋布置方式、剪力连接程度、接缝处材料对结构破坏模式、开裂荷载、抗弯承载力、荷载-位移曲线等力学特性的影响规律，揭示了预制板接缝处的应力分布规律；针对完全剪力连接的预制桥面板组合梁，提出了负弯矩作用下挠度计算的改进有效惯性矩叠加法 ...
