| Abstract: |
Multilevel decomposition optimization method decomposes a large problem into small subproblems to be solved separately and maintain effects between subproblems effectively by sensitivity derivatives, and it serves as a useful tool for design engineer team to work on a large structural optimization problem simultaneously and effectively. The present paper illustrates the application of this method on the optimization of a portal frame of a multi-story steel structure, and three level of substructure is chosen to solve the optimization problem. The 1st level is the entire structural system constrained to total lateral displacement, the 2nd level is each story frame constrained to story drift, and the 3rd level is related element sizing based on local constrains due to strength, serviceability, and member stability. |
