| Abstract: |
| Considering the uncertainties in structural system,the non-probabilistic reliability optimization method for structures is proposed based on the non-probabilistic set-theoretic model for structural reliability.In this method,the uncertainties are considered as interval numbers,and the non-probabilistic reliability of structures can be calculated by interval mathematics.Then the structural optimization problem,in which the non-probabilistic reliability index is taken as the constraint condition,can be solved through Lagrange multiplier method.The mass optimization for a truss structure is performed using the proposed method,and the optimization results illustrate its feasibility and effectiveness. |
