摘要
为研究半刚性连接钢框架的受力、变形性能及其破坏特点 ,对带双腹板角钢的顶底角钢连接钢框架进行了极限承载力静力试验。得到了半刚性连接钢框架的稳定极限承载力和对应的荷载—位移曲线。试验结果表明 ,半刚性连接钢框架要产生很大的变形后才达到极限承载力 ;对于有侧移半刚性钢框架结构 ,分析中必须考虑二阶效应。
One steel frame of top-and seat-angle with double web-angle connections was tested to study its ultimate strength,stress,deformation properties and characteristics of failures.The test process and results were presented in this paper.According to the test,the carrying capacity and the load-displacement curve were analyzed.
