| Abstract: | Based on the structure reliability analysis and results of structural optimization theory,the performance function and computative method of reliability index of the homogeneous truss structure under certain failure mode were derived and given,respectively.A mathematical model for optimization with the reliability index as the control parameter for structural optimization design was obtained,so that the reliability index-based optimization design of trussed structure was realized.The validity and general applicability of the method proposed were verified with an example of a rigid frame. |
| Keywords: | truss structure performance function reliability optimum design |
