The study of damage in the wake of recent earthquakes in the United States (1989 Loma Prieta, Northridge 1994), Japan (Kobe 1995), Canada (Saguenay 1988) and in other parts of the world has demonstrated the seismic vulnerability of existing buildings. In urban areas, this vulnerability, combined with a significant concentration of buildings built before the introduction of seismic standards, may result in a high seismic risk, even in areas where the seismicity is considered moderate. The seismic vulnerability of buildings can be assessed by quantifying the damage to structural and non structural elements, the use of fragility curves is a powerful tool in this area, and we propose in this paper to assess the seismic vulnerability of a reinforced concrete building by the use of fragility curves.

The behavior factor is a factor introduced in the seismic codes to reduce the seismic elastic forces obtained from a linear elastic analysis to account for energy dissipation in the short earthquake. This factor takes into account overall behavior of the dissipative capacity of the hysterical structure, to reduce its size to a standard of behavior with the introduction of elastic seismic forces equal intensity reduced. In general, the design value of the factor q is given in the seismic normalizations based on one type of structure dimensioned. But recent research has shown that this factor depends on other parameters. In this paper we propose to study the influence of global and local parameters on the evaluation of the behavior factor.
