| Abstract: | Based on non-probabilistic reliability theory and the optimization design method,considering the interval uncertainties regarding elasticity modulus and loaded force,stable non-probabilistic reliability-based optimization design of compressive bar is discussed and a method for stable non-probabilistic reliability based optimization design is proposed.Numerical examples and the results show that the model and method proposed have some theoretical significance and practical value. |

| Keywords: | compressive bar stable interval models non-probabilistic reliability optimization design |
