The Influence of Structural Damage Measure on IDA-based Structural Optimization

The reinforced concrete frame structure was taken as research object, three structural damage measures(DM) of vertex displacement, peak inter-storey displacement angle and maximum base shear force were selected, analysis and comparison of different DM on IDA method of structure optimization results and based on the characteristics. It is shown that the peak inter-storey displacement angle is preferentially used as the DM in the structural optimization analysis, and the vertex displacement can be selected for further analysis to correct the structural optimization.
