| description | The present paper follows the first part that aimed to develop a theoretical methodology able to derive building global damage from its structural components' damages: beams and columns in the case of RC frame buildings. This second part performs a validation and sensitivity study. It investigates the individual role of the beams and columns at the story level. It investigates afterwards the influence of the stories according to both their location along the height of the building, and their number. The theoretical predictions of the global damage are compared to reference values, which are obtained thanks to dynamic analysis performed on the OpenSees platform. Various damage distributions are tested: uniform as well as non-uniform damage for the whole components at a current story, symmetric, and non-symmetric damage distribution (at central or external columns), smooth or sharp variation from a story to its neighbors, concentration at upper or lower stories, and moderate or important damage level (low-to-medium or medium-to-high). Real ground motions are used as seismic input in order to investigate the method’s efficiency. The proposed method appears to be efficient, with acceptable accuracy, in the case of RC frame (from 4- up to 8-story height). Through the investigated cases, it can be pointed out that the adopted set of importance factor expressions (α and β factors) are relevant and suitable for seismic damage evaluation. It is worth noting that such methods can be helpful in calibrating and improving the current evaluation forms existing worldwide, for quick post-quake damage evaluation. |
