Abstract(s)
The collapse of a school building can be very dramatic, as it was the case of a school building in San Giuliano di Puglia (Italy) that has collapsed after the 2002 Molise Earthquake, or the Mexico City’s Enrique Rébsamen School, that collapsed after the 2017 Puebla Earthquake, killing many children. With this problem in mind, a computer software was developed for managing the seismic safety of school buildings in the context of the PERSISTAH project. The software complies three different modules: a school database, which is georeferenced, and the outputs can be displayed in the Google Earth; a module where it is possible to select the seismic action, which is used for the seismic assessment of the existent school buildings; and a structural performance evaluation module. In this paper, several computer strategies that were implemented in the developed software are explained and used for the seismic assessment of existing school buildings. The adopted analysis method (the N2 method) is based on the Eurocode 8 principles and rules, namely keeping in mind what is established in the Portuguese national annexes of the NP EN 1998-1:2010 and of the NP EN 1998-3:2017. Examples of the application of the developed computational strategies are presented. It is possible to conclude that when using dedicated computer routines, it seems to be possible to assess the nonlinear structural seismic behavior of a high number of buildings in a very fast way and with a high level of accuracy.
