杆件屈曲对单层球面网壳结构稳定性的影响
Member buckling of the effect on the stability of the single-layer lattice dome structures
摘要
Abstract
In order to study the member buckling of the effect on the stability of single-layer lattice dome structures,this paper used the nonlinear finite element method,and besides the node imperfection and member imperfection,utilized the smaller cross section members in different location of the structure in order to make those members buckle before the occurrence of the overall instability of the dome;the effect on the overall stability of K8 single-layer lattice dome structures from the member buckling at different location were studied under static load and earthquake load respectively.The research results show that under the static load,different location of the member buckling may reduce K8 single-layer lattice dome structures ultimate bearing capacity;Under earthquake load,the member before K8 single-layer lattice dome structures overall instability before buckling may reduce K8 single-layer lattice dome structures stiffness.关键词
