摘要

Site-city interaction is studied by using a red of buildings located on the Mexico City basin. A 3D modelling provided from vibrating system analysis and seismology method have been first used, which consisted in computing the total radiated wavefield caused by the shear base force developed at the soil-structure interfaces, when the structures are excited by seismic input motion. Finite elements method is also used, in case of simple red of buildings (2D modelling), in order to compute the multi-interaction effects. The radiated wavefield is compared to the input wavefield, to estimate the modification of the urban free-field motion.
