Description

Abstract: In this research work, the vibration reaction of a massless or massive raft foundation is investigated. The raft foundation is located on a homogeneous linear-elastic half space and faced to external dynamic loads. The elastic half space, signifying the medium of soil, is formulated by a semi analytical method in a complex response. Hence, this work is analyzed in time-domain by employing inversion fast Fourier transformation for impedance coefficients of subgrade soil. The foundation mat has to be discretized into a number of finite elements, which are combined with the corresponding sub regions of the elastic half-space through compatibility and equilibrium conditions. The proposed approach yields results which are in good agreement with those obtained in previous studies. Numerically works are shown to observe the influence of relative stiffness and aspect ratio of the foundation on the raft reaction.

Keywords: Dynamic loads, Elastic half space, Foundation, Semi analytical method, Semi rigid foundation, Vibration.
