摘　　要：首先介绍了超静定桁架满应力设计的概念,在引入桁架结构基本方程的基础上,通过建立桁架满应力设计的模型、确定桁架实现满应力设计所需满足的条件等作为理论基础,分析了结构形式、荷载、工况数三方面的因素对桁架结构实现满应力设计的影响,并通过算例对上述因素的影响进行了验证,从而为工程实践提供借鉴。In this paper,the concept of full stress design of statically Indeterminate Truss is presented firstly. Based on the basic equations of statically indeterminate truss ,by making the model and associated conditions which the full stress design of statically indeterminate truss need satisfy as the theoretical basis, the factors such as the structural forms, the load, and the number of working conditions are analysed, and examined by an calculating an example finally, so as to provide a reference for engineering practice.
