THE MODIFIED SIMPLEX METHOD FOR TOPOLOGY OPTIMlZATION OF SPACE TRUSS STRUCTURE WITH MULTIPLE LOADING CONDITIONS

In this paper , the member forces are considered as design variables, andconvex quadratic programming model of topology optimization for space truss structure isgiven under mutiple loading conditions. The linear interdependent problem for memberforces and K-T multipliers is formed by making use of its K-T condition)and can be solvedby the modified simplex method.
