Abstract: Considering the lack of theoretical analyses of simple and crude support schemes for structures in seismic regions, in this study, the seismic collapse fragility of a simply supported frame structure is quantitatively analyzed, using the incremental dynamic analysis (IDA) and a simplified structural analysis. The test structure is a three-story two-bay small-column RC frame structure. The fragility and seismic collapse ability of the small-column-design structure before and after being supported are compared and analyzed, as well as the fragility and anti-seismic collapse ability of the regular design-frame structure. The results demonstrate that the simple external inclined support of timber components can greatly improve the anti-collapse capability of structures under seismic load, which is of significance to disaster prevention and mitigation. © 2018, Editorial Department of Journal of HEU.
