- Abstract:
- The multi-objective quick group search optimization (MQGSO) algorithm was applied to the optimal design of doublelayer spherical shells. The optimization objectives were the minimum value of the maximum displacement and the weight of the structure. Taking the doublelayer spherical shells as an object, the Pareto frontier of the optimization example structure had the full and broader distribution. Corresponding to the multi-objective optimization results and the singleobjective optimization results, the time history response analysis of optimized structure under multi-dimensional earthquake action was carried out. The results show that the multi-objective optimization results are better than those of the singleobjective one. The dynamic characteristics of the doublelayer shell example prove that the MQGSO algorithm can effectively deal with the multi-objective optimal design of complex spacial structures.
