拉压性能不同材料的桁架结构的极限分析

Limitation Analysis on the Truss for Materials with Different Behavior in Tension and Compression

对拉压性能不同材料的桁架进行了极限分析 .证明材料的拉压性能不同对桁架结构承载能力的影响是很明显的 .

Limitation analysis on the truss for materials with different behaviour in tension and compression is investigated. It has been shown that there was a great influence of the different behaviour effect on the bearing capacity of the truss structure . Moreover, the limit load formulate of this paper could give some advices for the engineering designers.
