摘要
整体稳定性是单层网壳结构设计中的一个关键问题.在进行此类结构的优化时,必须考虑整体稳定性的影响才能得到符合规程要求的设计.本文综合考虑了位移、应力和杆件稳定以及结构整体稳定性条件,提出了基于最优准则法的优化设计方法,可按照钢结构设计规范和网壳结构规程的要求,对单层网壳结构进行杆件截面设计.
Structural stability is a key problem in the design of single-layer lattice shells, In the optimization of such structures, the effect of structural stability must be considered to obtain a design accordi which stress, ng with can be the code. An optimization method based on the used in optimum design of single-layer lattice optimality criteria is proposed in this paper, shells. The constraints of displacements, member stability and structural stability are considered. The requirements of Code for Design of Steel Structures and Technical Specification for Latticed Shells are fulfilled.
