| Abstract: | The problem of optimization design of structure with random parameters under random loads is studied. The optimal mathematical model of engineering structure with the reliability constraints on dynamic stress and displacement and constraints on the upper and lower bounds of the design variables is built. A complex method is used in the optimization. The example illustrates the correctness and practicability of the optimal model and solving approach. |
