Abstract

An efficient method is presented for optimum design of skeletal structures where the design variables can be continuous or discrete. The design variables are sizing variables such as cross sectional areas and shape variables such as coordinate of joints. A penalty function is used to achieve the discrete solution. The discrete variable optimization is carried out after the completion of the continuous solution. In both the continuous and discrete optimizations all the structural responses such as forces and displacements are approximated as functions of some intermediate variables. Thus the number of required analyses is reduced during the optimization process. A planar truss and an outlet gate chosen as a space truss are optimized to demonstrate the efficiency of the proposed technique.
