MULTIPLE STRUCTURE-SOIL- STRUCTURE INTERACTION AND COUPLING EFFECTS IN BUILDING CLUSTERS

摘要: We study the presence of multiple structure-soil-structure interaction effects in idealized building clusters during earthquakes, their effect on ground motion, and how individual buildings interact with soil each other. seek to characterize, through a parametric approach, coupling between soil, foundation, structural response buildings, including torsion, surrounding structures. simulate motion historical earthquake focus simplified symmetric asymmetric models located soft soil. use as reference isolated models, which allows us separate different contributing factors distinguish soil-structure coupled structure-soilstructure effects. Numerical results show that vary number dynamic properties separation, impedance respect Our indicate torsion are also relevant. Interaction appear an increased spatial variability significant reductions buildings’ base at frequencies above natural building-foundation systems.
