摘要
本文就可靠性分析问题建立了概念清晰、含有基本变量的安全余量,给出板元和梁元失效后,减缩刚阵和反向节点力的计算公式。
We established the safety margins contained basic variable with the distinct concept,and gave the calculating formulae of the reduced member stiffness matrix and the opposite sign of the equivalent nodal force with failure occurred at beam-member or plate-member.
