Transient response of a group of rigid strip surface foundations

A numerical procedure is proposed to investigate the transient response of a group of rigid strip foundations resting on an elastic, homogeneous half‐space subjected to either external forces or seismic motions. A fundamental solution is presented for uniform strip loadings with Heaviside function time‐dependence applied on the half‐space. In the procedure, each of the foundations is discretized into subelements. The tractions between the half‐space and the subelements are assumed constant at every time step. The through‐soil coupling effects between the foundations are studied numerically.
