Incremental Dynamic Analysis of an Existing Reinforced Concrete Frame

The article evaluates the damage assessment of a plane reinforced-concrete frame structure with the application of a nonlinear incremental dynamic analysis (IDA) on a numerical model of the building. Behavior assessment and fragility is based on a plane model obtained by analyzing the real frame structure. The nonlinear analysis is repeated for each incremental increase of earthquake intensities. For the estimation of structure vulnerability due to earthquake motion, the incremental dynamic analysis was applied on the numerical model of the building - a plane reinforced concrete frame. The fragility curves, constructed from IDA results, represent a very useful probabilistic tool for estimating earthquake behavior.
