Seismic fragility assessment of a RC frame considering concentrated and distributed plasticity modelling

Abstract Researchers must decide on how they will model the non-linear material response in a Finite Element simulation to assess seismic vulnerability. This paper aims at giving an insight into these modelling decisions by comparing Fiber and Lumped Plasticity Models static dynamic analysis RC frame. The methodology is based performance-based earthquake engineering determine expected damage structures. results indicate that both models are good agreement with analysis, when considering Extensive Complete Damage Limit States analysis. choice between them depends main goals of research resources available, since have significant difference processing time.
