Abstract. For earthquake-resistant design, structural degradation is considered using traditional strength modification factors, which are obtained via the ratio of nonlinear seismic response degrading and non-degrading single-degree-of-freedom (SDOF) systems. In this paper, with aim to avoid compute a methodology based on probabilistic hazard analyses (PSHAs), proposed in order obtain factors ...

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 m...
