Resumen:

Seismic waves can significantly amplify in firm soils with abrupt geometrical changes due to topographical effects. This amplification is strongly dependent on both frequency content, seismic intensity, and duration, in particular when soil non-linearities are expected to occur. This paper presents a case study of the topographic effects of a typical hill slope on firm soil, on a building siting in top of it, such as those found in the western area of Mexico City, due to subduction and normal earthquakes. The performance of the building-hill system was evaluated using sets of finite difference models developed with the program FLAC3D. From the numerical study the seismic response of the slope was evaluated, accounting for seismic soil-structure interaction effects in the distribution of factors of safety and ground deformations during the dynamic events. The difference on expected damage in the building and hill was established for each seis-mogenic zone considered. © 2019 Associazione Geotecnica Italiana, Rome, Italy.
