【摘要】 对带双腹板顶底角钢连接以及外伸端板连接空间钢框架进行了非线性有限元分析,研究了空间钢框架的静力承载性能与节点刚度的关系,得到了不同节点刚度对空间钢框架位移和内力的影响结果,对工程应用具有一定的参考价值。更多还原

【Abstract】 Nonlinear finite element analysis for space steel frames with connections of top-seat-angle with double web-angle and extended endplate is performed in this paper.The relationship between joint stiffness and static behaviors of space steel frames is simply studied,the influence of joint stiffness on the deformations and internal forces of the space steel frames are gained.Finally,some design suggestions are recommended.更多还原
