| Abstract: |
| The ICM (Independent, Continuous and Mapping) method was applied to the frame structures. A topological optimization model for the frame structures under the multi\|loading cases was established, which takes the weight as an objective function and subjects to the stress and displacement constraints. By using the smooth function and filter function, the discrete variables and continuous variables were transformed conveniently. Synthesized coordination between the topological solutions with the stress and displacement constraints under the multi\|loading cases was considered. Numerical results show that the optimized frame structures are reasonable which are different from trusses. |
