摘要
本文编制了网架结构优化设计和极限分析的计算程序．并对网架结构进行了分析。通过实例．将结构的优化设计和极限分析有机地结合起来，从而提高了网架结构的极限承载能力。
In this paper, the calculation program of optimal design and ultimate analysis of truss structures is worked out. And truss structures are analyzed. Through calculation of practical example, based on combining the optimal design with the ultimate analysis,the ultimate loading capacity of truss structures is increased.
