Abstract:
Fragility curves are used to show that structural damage under various levels of seismic excitation is likely to surpass specified damage states by means of earthquake intensity-damage relations. In this study, seismic fragility curves are developed for reinforced concrete (RC) structures typically built in Iran. The structures considered in this study have RC Intermediate Moment Frame systems, and are designed according to Iranian Earthquake code termed standard No.2800 (2005). In order to probabilistic seismic assessment of these sub-classes, full 3-Dimensional finite element models are developed and analyzed with OpenSEES. The uncertainty of ground motion and material are considered in the fragility analysis. The engineering demand parameter in terms of maximum inter–story drift ratio are developed for 20 different far-source sets of ground motion records. The structure's vulnerability is determined according to HAZUS-MH damage states.
