| Abstract: | 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. |
