摘要
文中利用有限元分析软件ANSYS对广州市新体育馆辐射桁架大型钢板支座节点进行了弹塑性大挠度分析 ,获得了受荷时的塑性区分布规律及极限承载力 ;这些计算结果为验证节点构造的合理性、对补充和修改设计提供了理论依据。
An inelastic large deflection finite element analysis for a real engineering support joint composed of large size steel plate and loop box beam was completed by using the finite element package program ANSYS,the plastic zone and ultimate strength spread were gained,so as to confirm the validity of joint construction and then renew the design.
