Improved Fragility Relationships for Populations of Buildings Based on Inelastic Response

Abstract eng:
In this paper, a new procedure for fragility analysis of populations of buildings is proposed. The procedure is divided into four components, namely (i) capacity of building; (ii) earthquake demand; (iii) structural assessment and (iv) fragility curve generation. Each of these elements is handled rigorously in order to arrive at reliable fragility relationships. The capacity of the building is represented using either analytically-derived or expert-opinion-based pushover curves. Earthquake demand is modeled by synthetically generated site specific ground motions for the Central and Eastern United States (CEUS). Structural assessment is carried out using an advanced Capacity Spectrum Method (CSM). Finally, fragility curves are presented in two different formats, conventional and HAZUS-compatible. The proposed procedure is applied to a wide range of buildings from construction classes of wood, steel, reinforced concrete, masonry and mobile homes. The uniformly derived fragility relationships are proposed as a reliable tool for earthquake impact assessment.
