Retrofitting and Strengthening Quality Evaluation from Rigidity Variations of a Damaged Building


Abstract eng:
The rigidity of a six-story shear wall building, damaged by the May 21, 2003 Boumerdes (Algeria) earthquake is evaluated before the event, in its damaged state, and after retrofitting, using the estimation of the frequency and damping factor of the structure. The pre-event parameters are estimated through a numerical analysis, based on the structure drawings complemented by a micro-tremor investigation of an identical non-damaged building located on the same site. The damaged and retrofitted parameters have been obtained using only micro-tremor recordings on the studied building. The variation of the frequency and damping factor during the three stages of the building went through allows to evaluate its rigidity changes, and therefore to control the quality of retrofitting and strengthening.
