NONLINEAR FINITE ELEMENT ANALYSIS OF SEISMIC BEHAVIOR OF SEMI-RIGID CONNECTION STEEL FRAME
-
摘要: 利用有限元分析软件ANSYS对带双腹板、顶底角钢半刚性连接的钢框架进行非线性有限元分析。在分析的过程中考虑了连接的非线性、几何非线性以及材料非线性等因素。并将计算结果与试验结果进行对比,探讨半刚性连接的柔性对钢框架的影响,为今后的半刚性连接钢框架的设计提供参考。Abstract: nonlinear finite element analysis of the steel frame with top- seat angle and double web-angles semi-rigid connection is carried out with ANSYS finite element software. In the procedure of the finite element analysis, connective, geometrical and material nonlinearities are considered. The analytic results are compared with experimental results, and the influence of semi-rigid connection's flexibility on steel frame is also explored, which provides some references for the design of steel frame with semi-rigid connection in the future.
