Evaluation of damage index based seismic performance of existing low rise RC buildings retrofitted by metallic energy dissipating devices

Existing non-seismically detailed low rise reinforced concrete buildings have higher seismic risks that are dependent on their seismic capacities and demand of building sites. Seismic risk analysis can be performed considering probabilistic characteristic of the structural damage which is represented as a damage index. Based on the probability distribution of selected damage index, the seismic risk analysis demonstrates that the application of well-designed MEDDs to the prototype existing low-rise RC building can reduce its potential seismic risk.
