摘要
采用有限元软件ANSYS对一两跨6层的钢框架模型分别进行静力、特征值屈曲和模态分析,研究端板半刚性连接钢框架在外荷载作用下的性能,通过与相应的刚性连接钢框架比较,得出端板连接的半刚性对结构内力、位移、稳定性和周期产生的影响,并为使结构设计更合理和结构真实状态更相符而提供了理论依据.
With the help of the finite element analysis software of ＂ANSYS＂, a two-bay six-floor steel frame with semi-rigid end-plate connections was analyzed by static analysis, eigen buckling analysis and modal analysis. The behaviors of internal forces, displacement, stability and period with different degrees of rotational stiffness of semi-rigid steel frame were discussed. By comparison with the behaviors of relevantly rigid steel frame, the influence of semi-rigid end-plate connection on those above-mentioned behaviors was found. Finally, some conclusions were made to have the structural design more reasonable and agreeable with actual appearance of the structure.
