Abstract:

In this work fragility analysis of reinforced concrete and steel structures withinfill walls is performed.For this purpose a fuzzy-based fragility assessment framework for evaluating 3D framed structures is proposed taking into account various sources of uncertainty. In particular, randomness on the material properties and on the seismic demand is considered. The proposed framework requires the development of a fuzzy nonlinear static analysis model in order to define the limit states. The fragility curves are expressed in the form of a two-parameter lognormal distribution.
