Estudio de Propagación de Ondas Sísmicas - Caso Particular de Sitio

One of the problems faced by the civil engineer is the adequate design of structures. In this regard, there are worldwide standards that regulate the design and construction of buildings subject to seismic actions. The purpose is to make the structures ductile, i. e., that they can undergo large deformations without loss of resistance and that they do not collapse even when the most severe earthquake occurs. In many standards worldwide, it is established to carry out particular studies of site or seismic wave propagation in important works, however, its application is not ruled out in works that could be considered as not very important due to the economic aspect, while still being of great importance. economic aspect, while still being important from the point of view of saving lives. In this sense, in those cases in which the building is located in the proximity of active faults or there is the presence of there is the presence of soil strata susceptible to liquefaction or soils that degrade their stiffness or strength with the stiffness or strength with deformation under the effect of cyclic loading should be the subject of the object of the realization of particular site studies. For this reason, the following paper presents the the methodology used to carry out a particular site study is presented in the following work, showing, among other aspects, the degradation of stiffness and strength of soils, the evaluation of the liquefaction potential of sands, the levels of deformation experienced by the soil strata and the design spectrum obtained as input for the dynamic analysis of structures. dynamic analysis of structures.
