The probabilistic methodology is developed in order to assess the seismic performance under a new generation of performance based earthquake engineering. Three of the four steps involved in the above methodology are included in this study. Hazard Analysis, represented by the peak ground acceleration as intensity measure; Structural Analysis, with lateral drift as engineering demand parameter; and Damage Analysis, where the damage is measured by the probability of exceeding certain damage state. The uncertainties are involved in each step as follows: In the hazard analysis, actual records are selected and scaled to the intensity target values. These records include the actual uncertainties in some parameters such as duration and frequency contents. For the Structural Analysis, the uncertainty is introduced by means of a random variable for the yielding point in the capacity curve calculated for the structure; which is used as envelope in the nonlinear single degree of freedom analysis for the frame. The uncertainty is produced by simulation on the material capacity. Finally, the damage uncertainty is given by the fragility functions, which relate the structural demand parameter (lateral drift) with the structural damage states for the building. The damage probabilities are integrated for all the selected records and the values of yielding strength. The final result is given in terms of the probability of being in each damage state given a PGA value and plotted in fragility functions.
