钢框架与节能复合墙板连接方式的试验研究

Experimental research on connections of steel frames and energy-saving composite panels

钢框架与复合墙板通过一定方式进行连接,形成一种协同作用的结构体系,这种体系具有良好的抗侧力性能。为了研究不同连接方式对结构抗侧力性能及滞回性能产生的影响,设计了墙板与钢框架梁连接方式和柱连接方式两榀足尺模型,并对其进行了水平循环加载试验。研究结果表明:这种结构体系能有效提高结构的极限承载力与抗侧刚度;相比梁连接方式,柱连接方式表现出更好的延性与耗能能力,结构的整体性与可靠性也较好,其抗震性能优于梁连接方式。

Steel frame and energy-saving composite panel can be connected in specified arrangements to form a coordinating structural system,which has the good property of lateral resistance.In order to study different effects of lateral resistance and hysteresis characteristic between two arrangements,two full-scale models with a conducting low-cycle reciprocating loading test were designed,which were called beam connection and column connection.It was proved that both systems could effectively improve the ultimate bearing capacity and lateral stiffness.Compared with the beam connection,the column connection showed a better ductility,energy dissipation,structural integrity and reliability.In addition,the column connection could give better seismic performance than the beam connection.
