摘　　要：根据有限元理论及最优化理论 ,同时考虑结构受力特点 ,给出了塔架体系在可靠度约束下的最优化设计方法。编制程序对某通讯塔进行风载下的最优化设计 ,得到了较满意的结果。Based on finite element theory and optimization theory, considering mechanical properties of the structure, the reliability optimization design method of tower truss system is presented. Finally, an optimization design is made to a communication tower under winder load the computer program compiled by the autors, and satisfactory results are gotten.

关 键 词：塔架结构 可靠度 最优化设计 风载
