Assessment of the Urbanization Effect on Seismic Response

摘要: This article introduces two analytical methods that aim at investigating the effect of urban environment on seismic motions. We regard cities as a periodic distribution simple oscillators. The response to vertical incident SH wave is analyzed by considering city with macroscopic point view. As first approach, buildings described mean impedance soil–city interface. enables us identify mechanical coupling parameter governs magnitude interaction and determine characteristic time response. A second, more refined model based approximated fields radiated each building leads introducing boundary layer describe multiple interactions effect. provides an assessment both free soil motion basement motion. Applications are given for monofrequency multifrequency in case homogeneous stratified substratums.
