The dynamic pres.ure dis.ribution on a rectangular plate attached to a rigid wall and s.pporting an infinitely large extent of fluid s.bjected to a harmonic ground excitation is.evaluated in the time domain. Governing equations.for the fluid domain are s.t cons.dering the compres.ibility of the fluid with negligibly s.all change in dens.ty and a linearized free s.rface. A far boundary condition for the three-dimens.onal fluid domain is.developed s. that the far boundary is.truncated at a clos.r proximity to the s.ructure. The coupled problem is.s.lved independently for the s.ructure and the fluid domain by trans.erring the acceleration of the plate to the fluid and pres.ure of the fluid to the plate in s.quence. Helmholtz equation for the three-dimens.onal fluid domain and Mindlin＇s.theory for the two-dimens.onal plate are us.d for the s.lution of the interacting domains. Finite element technique is.adopted for the s.lution of this.problem with pres.ure as.nodal variable for the fluid domain and dis.lacement for the plate. The time dependent equations.are s.lved in each of the interacting domain us.ng Newmark.fl method. The effectivenes. of the technique is.demons.rated and the influences.of s.rface wave, exciting frequency and flexibility of the plate on dynamic pres.ure are inves.igated.
