Estudio de riesgo sísmico, evaluación y rehabilitación del antiguo edificio de la Facultad de Economía de la UCSG.

Abstract

In the present work, an evaluation of the seismic risk of one of the buildings of the Universidad Católica Santiago de Guayaquil (former Faculty of Economics) was carried out, beginning with the collection of information on the structure (architectural plans, year of construction, structural plans, person in charge of construction) in order to begin with the first chapters of this work. Soil studies carried out for the construction of the postgraduate building of the University were taken as a reference, which determined the type of soil that was found under the building (type B) in order to begin the creation of the spectra. Once obtained, a three-dimensional model of the structure was made in the ETABS program, which managed to know the behavior of the structure in future earthquakes. The resistance of the concrete was determined through a sclerometry test (400kg/cm2) in order to know the drifts between the floors of the structures, which were less than 2%. A non-linear analysis of the structure was made with the 2500-year earthquake to observe the formation of the plastic hinges, which were within the B - C range, which determines that the structure did not collapse with the analyzed earthquake. Subsequently, the capacity of the elements was carried out, which complied. Finally, the results were concluded, specifying that the structure does not need a rehabilitation or any reinforcement, but if any recommendation is named that could be made in the building.
