摘　　要：冷弯薄壁型钢住宅体系作为一种绿色建筑在我国已经开始得到应用,但相应的理论和试验研究极少。通过对这类住宅体系的墙体轴压性能进行试验研究和有限元分析,提出了构件稳定设计的有效计算长度系数,并与AISI规范(1996)计算结果进行了比较。研究表明墙体覆盖面板可以提高墙体骨架的承载力,相当于蒙皮效应。所做工作可为我国编制这类新型住宅的设计规范提供参考。Cold-formed steel residence,as a kind of green architectures,has obtained more and more applications in China.But there is few researches either in theories or experiments.The experiments on the behaviors of the wall system under axial compression are carried out and the FEA studies are made.The effective length factor is sugges- ted for the stability design of the wall columns,and compared with the results of the AISI code(1996).The study shows that the packing panel can highly improve the walls' bearing c...
