Para actualizar en algunos aspectos el análisis de riesgo del Plan de emergencias sísmicas en Cataluña (SISMICAT) y contribuir al estudio de riesgo a escala municipal, se propone una metodología de tipo “intermedio” aplicable al conjunto de HOSPITALES y de CENTROS EDUCATIVOS u otros edificios vulnerables y esenciales.

To do that, the mechanical properties of the materials have been considered random and a set of real accelerograms are scaled in such a way that the mean of their response spectra is similar to the elastic response spectra of the Eurocode EC-08. Performing a series of nonlinear dynamic analysis in the time domain, the probability density function of the maximum displace-ment at the roof of the structure is obtained. Afterwards, the mean capacity curve of the structure is calculated in probabilistic terms. The static and dynamic nonlinear structural analyses are performed with the program RUAUMOKO 2D. The capacity curve allows defining the states of seismic damage of the structures. Ac-cording to the methodology proposed by the ATC 40, the expected seismic damage of a structure can be cal-culated from its capacity spectrum and from the horizontal displacement demand at the roof level. In order to calculate the latter, the equal displacement approximation will be applied and will be compared with the de-mand of the structure calculated by means of the before mentioned nonlinear dynamic analysis. The fragility curves of the structures are then calculated starting from the obtained damage states. The expected structural damage is finally obtained entering in the fragility curves the spectral displacement obtained by using both, the ATC 40 method and the nonlinear dynamic method. The results obtained from static and dynamic analyses are finally compared and discussed from a probabilistic point of view.

In the Eixample district, approximately the 65% of the buildings fit the main features of a building design based on unreinforced masonry (URM) without any consideration of the seismic action. The buildings of the Eixample district are not isolated, quite the opposite, they are built as a part of a squared aggregate (113,3m per 113,3m) which includes approximately 22 buildings. Since 1960, the major part of the demolished URM buildings has been substituted by reinforced concrete (RC) buildings. As a consequence of this substitution, we expect a change in the seismic vulnerability of the buildings aggregate. In order to evaluate changes in the dynamic behavior of an aggregate, we performed different pushover analysis using the TreMuri software. A comparison of results corresponding to aggregates of URM-buildings and aggregates including RC-buildings is presented.

For this purpose a specific methodology is proposed. The developed methodology allows explicitly consider important uncertainties that are present in the main elements, that are used to estimate the seismic risk of buildings. One of these elements is the seismic vulnerability of each building, which is mainly represented in the proposed methodology through probability density functions that describe the variation of a vulnerability index. In the developed methodology, the seismic vulnerability is considered as a property that is changing through the time. Therefore, it is possible to estimate seismic vulnerability curves for different stages on the future life of a building. The methodology was used to estimate the seismic risk of 59,905 buildings of Barcelona. According to the results, in average, 53,152 buildings have a probability lower than 5% of suffer some kind of collapse during the next 50 years. If the government of Barcelona conducts a program to do a seismic rehabilitation of buildings, then the first buildings that could be evaluated for rehabilitation purposes could correspond to the 1,317 buildings, which were identified in this work as the buildings with the highest seismic vulnerability.

For this purpose a specific methodology is proposed. The developed methodology allows explicitly consider important uncertainties that are present in the main elements, that are used to estimate the seismic risk of buildings. One of these elements is the seismic vulnerability of each building, which is mainly represented in the proposed methodology through probability density functions that describe the variation of a vulnerability index. In the developed methodology, the seismic vulnerability is considered as a property that is changing through the time. Therefore, it is possible to estimate seismic vulnerability curves for different stages on the future life of a building.
