Abstract

In this study, an analytical approach was adopted to construct fragility curves for thin RC walls that are the vertical components of the lateral-force-resisting system of buildings to earthquakes typically used in Lima, Peru since 1998. The main feature of these walls is the use of electro-welded wire mesh as main reinforcement instead of conventional bars. The numerical models were constructed based on the results of experiments. A series of non-linear dynamic response analyses was performed using two ground motion datasets. The damage ratios were estimated with respect to four damage states performing seismic response analyses. The fragility curves were obtained assuming that the damage ratios follow lognormal distributions. Comparing the fragility curves obtained from the two datasets, the effects of ground motion characteristics to the responses of RC shear walls are discussed in this paper.
