摘要
为研究不同连接方式下中空内模水泥(hollow inner-formwork cement,HIC)墙板-钢框架结构的抗震性能,文章设计了 2种内嵌式连接方式.通过对1榀钢结构空框架足尺试件和2榀内嵌HIC墙板的钢框架足尺试件进行拟静力试验,分析不同试件的破坏特征、承载力与变形性能、刚度退化和耗能能力,综合评估该结构的抗震性能.研究表明:内嵌式连接下,HIC墙板-钢框架结构的抗侧刚度提高3.31倍以上,峰值承载力提升29％以上,延性系数达到6.20,最终破坏时的总耗能增加约47％;结构塑性开展过程稳定有序,墙板与钢框架采用"梁上点连接"或"周边线连接"时,结构的破坏模式存在差异,但两者均能提供安全可靠的连接效果.
Abstract
In order to study the seismic performance of hollow inner-formwork cement(HIC)wall pan-el-steel frame structure under different connection methods,two types of embedded connection meth-ods were designed.The damage characteristics,bearing capacity,deformation performance,stiffness degradation and energy dissipation capacity of the different specimens were analyzed by pseudo-static test on one-bay full-scale specimen of empty steel frame and two-bay full-scale specimens of steel frame with embedded HIC wall panels,and the seismic performance of the structure was evaluated comprehensively.The results showed that the lateral stiffness of HIC wall panel-steel frame structure with embedded connection increased by more than 3.31 times,the peak bearing capacity increased by more than 29％,the ductility coefficient reached 6.20,and the total energy consumption at the final failure increased by about 47％.The plastic processes of the structure were stable and orderly,in which the structural damage modes differ when the HIC wall panels were connected to the steel frame by beam point connection or perimeter line connection,but both of them were safe and reliable.
