摘要
提出一种超静定桁架极限载荷的分析方法。利用一维增量弹塑性有限元法对桁架进行分析 ,通过优化选取桁架承受极限载荷时增量法中载荷增量的步长 ,从而得到各种加载方式下的极限载荷。实例表明可得到较高的计算精度。
A method for analysing the limited load of superstable truss by FEM is presented,the truss is anulysed by use of one dimensial incremental elasto plastic FEM,and optimal calculate the load incremental factor as the truss being loaded by limited load,thus the limited load of the superstable truss under various loading can be gained.The examples show that the method has higher calculating precision.
