| 摘 要： | 通过对顶底角钢腹板双角钢连接钢框架的低周往复荷载试验,对其受力过程、破坏形态、滞回曲线、骨架曲线、延性、耗能能力等抗震性能进行了较为深入的研究与分析.采用非线性有限元方法对这种半刚性连接钢框架进行了计算,其结果与试验结果吻合良好,为该种连接钢框架的结构设计及理论分析提供了依据.

| Abstract: | Through the experiment on steel frames with two web flange and top-seat connections under low reversed cyclic loading,the failure pattern,hysteresis curves,skeleton curves,ductility and energy dissipation,etc. were studied systematically.A nonlinear finite element analysis method was adopted to analyze the semi-rigid steel frame,calculation results being in good agreement with those of the tests,a reference basis is provided for construct design and theory analysis of such connection frames. |
