An Efficient Three-Dimensional Soil-Structure Interaction Analysis for Incident Plane Waves
Abstract eng: An efficient method is proposed for transient response analysis of three-dimensional structures resting on viscoelastic half-space for incident plane waves. The formulation consists of two parts: (a) the time domain formulation of the unbounded soil which is modeled by lumped-mass explicit finite element and transmitting boundary condition and (b) the coupling algorithm between the soil and structure through foundation. It is an implicit-explicit method, in which the soil is analyzed by explicit procedure avoiding equation solving, and the structure is analyzed by implicit procedure. The time step of explicit and implicit procedure can be different. Examples are given to demonstrate the feasibility of this method, and the influence of incident angle on the structure response is investigated. The results obtained indicate the possible importance of the effects introduced by nonvertically incident SH wave.
