中高层装配式复合墙体抗震性能试验研究
Experimental studies on seismic behavior of mid-highrise prefabricated composite walls
摘要
Abstract
In order to enhance the bearing capacity and to improve connections of prefabricated com-posite walls ,three mid-highrise prefabricated composite wall specimens using a dovetail joint vertical connections and pre-welding plate horizontal connections were designed and tested .Through the qua-si-static test ,the failure mechanism ,hysteresis characteristics and the stiffness degradation ,strength degradation ,energy dissipation capacity of the specimens under different vertical boundary reinforce-ment ratios were studied .Test results show that this kind of prefabricated wall shows a good act of collaboration and reasonable failure mode .The vertical boundary reinforcement ratio has influence on the peak load ,stiffness degradation ,strength degradation ,respectively ,and the prefabricated com-posite wall shows a high load carrying capacity and energy dissipation capacity based on a rational de-sign .Compared with the multilayer composite wall ,mid-highrise composite wall shows a performance of connection reliability and high capacity ,and the results can provide support for practical applica-tions in mid-highrise ecological composite wall structure system .关键词
