In this study, we focus at one structure's type, namely a quasi symmetrical reinforced concrete structure with structural walls. The structure is discretized into a set of macro-elements, each macro-element being representative of a structure's floor. The estimated performance level achieved during a seismic action is obtained from capacity curves (based on static pushover analysis). The performance analysis of the structure is a probabilistic analysis since both the response spectrum (action) and the materials properties (resistance) are random. A parametric study was conducted to determine the vulnerability cumulative distribution functions and to identify the parameters that control them.
