| Abstract: |
| For complex structure containing spacial beam element, we propose an unified approach of multi-design parameters instead of single one, which apply optimal strategy of two level about partial and whole optimization and unified primal solution of geometric programming by forming function's relations between multi-design parameters and mechanical measure of sectional area by using Duffin condensation formula. Numerical examples show that the computational efficiency of the method presented in the paper. |
