Selection Criterion of Reanalysis Methods for Plane Truss Optimization

Structural reanalysis methods have been proposed to improve the efficiency of structural analysis. However, are typically only applicable their specific type modification. Since optimization process often involves multiple types modifications, it is necessary establish a criterion for selecting most suitable method each modification, aiming accelerate process. In this study, effects different modifications first analyzed. A qualitative correspondence established between and mainstream methods. Secondly, quantitatively analyzed from aspects indicators clarifying accuracy requirements. Finally, in conjunction with Topology Shape Annealing (STSA) algorithm, methods, which plane trusses, established. To verify validity selection criterion, two numerical examples conducted. The results show that can effectively computations.
