AN IMITATIVE FULL-STRESS DESIGN METHOD FOR STRUCTURAL OPTIMIZATION WITH DISCRETE VARIABLES

An imitative full-stress design method was presented for structural optimum design with discrete variables. The structural optimum design with discrete variables under stress and section size constraints can be directly calculated by this method, and the structural discrete optimization with multi-loading, multi-variable and multi-constraint (including stability and displacement constraints) can also be dealt with by using the indtative full-tress design method. The method was illustrated by two numerical examples. The results of the examples show that the method is efficient.
