摘要
本文把桁架结构的地震可靠性分析和最优化设计方法结合起来，以结构的地震失效概率为目标函数，给出一种考虑地震可靠性的桁架结构的优化方法。该方法能够解决线性桁架体系在平稳的随机地震地面运动激励下的优化问题，并在给定投资的条件下设计出最安全可靠的桁架结构。
In this paper,a new reliability-based optimal method of trusses is presented. The reliability analysis and optimal design technology are used in this method,and the objective function is the failure probability of structures under seismic loads with investment constraint condition. This method can be used to solve the optimal problem in which the linear trusses are stimulated by the stationary random process of seismic ground motion and the safest trusses can be designed under the constraints of the given investment.
