摘要:

将梯度优化法与有限元法相结合,探讨了隐式功能函数可靠度算法,通过算例对比分析半刚接与刚接钢框架系统刚度的主要失效模式,同时用PNET法探讨了节点转动刚度和P-△二阶效应对结构系统刚度可靠度的影响.结果表明,半刚接与刚接钢框架的系统刚度的主要失效模式基本一致,层间位移较大形成了结构系统刚度的主要失效模式;半刚性连接对结构系统刚度可靠度的影响较大,并且增大了P-△二阶效应的影响.

Abstract:

Combining the gradient optimization method with the finite element method, the implicit functional function reliability algorithm is discussed, the main failure modes of the stiffness of semi-rigid and rigidly bonded steel frame systems are compared and analyzed by example, and the influence of joint rotational stiffness and P-△ second-order effect on the stiffness reliability of structural systems is discussed by PNET method. The results show that the main failure modes of the system stiffness of the semi-rigid joint and the rigidly connected steel frame are basically the same, and the large displacement between the layers forms the main failure mode of the stiffness of the structural system. The semi-rigid connection has a great influence on the stiffness reliability of the structural system, and increases the influence of the P-△ second-order effect.
