摘要
钢框架住宅主体结构本身抗震性能良好,故围护墙板与钢框架的连接方式对房屋整体的承载能力、抗震性能、延性等具有重要影响,结合东北地区的气候条件、工程应用现状,优化了围护墙板构造,设计了2种柔性螺栓连接方式。在理论研究的基础上,制作了1∶2缩尺试件,进行了围护体系整体抗震性能的试验,对比分析得到了不同围护体系的承载力、耗能、延性等指标,验证了柔性连接的明显优势,为钢框架结构的工程应用提供了参考。
The main structure of steel frame houses has good seismic performance,so the connecting way between envelope wall and steel frame has important influence in bearing capacity,seismic behavior,ductility,etc in the whole house.According to climatic conditions and the present application situation in the severe cold region in Northeast part of China,the envelope wall panels are improved,and two flexible connection ways of bolts are designed.On the basis of theoretical study,the reduced scale(1∶2)specimens are made,the experiments to test the overall seismic capacity of envelope system are made to make a comparative analysis and get some indexes of the envelope systems such as bearing capacity,energy consumption and ductility,etc.,which verifies the obvious advantage of flexible connection and provides reference for the constructional application of the steel frame housing.
