Simplified Seismic Loss Estimation of RC Frame using Component-performance-based Methodology

A framework of simplified probabilistic seismic loss estimation of RC frame using component- performance -based methodology was presented in this paper. Firstly, component- performance -based methodology was introduced, and component performance level was measured using elasto-plastic rotation angle of structural component. Then structural performance level was determined by the statistics of damaged components distribution. Additionally, the relationship between the structural performance level and loss ratio of RC frame was established. Last, expected seismic loss ratio of 3-storey RC frame was studied in detail. This study reveals that the simplified probabilistic framework proposed herein could be used in RC frame.
