Abstract: In this paper, axisy mmetric nonlinear dynamic equations of fiber reinforced symmetric cross-plyla urinated flat spherical shells are found including transverse shear deform anon.Using one dimensional wave-damping method,the interaction of soil and structure is investigated. The nonlinearly dynamic response of shallow-buried flat spherical shell with its edge elastically restrained against rotation is discussed for shock wave propagation in soil.In the numerical co mputation, the effects of various material parameters and transverse shear deformation on dynamic response are considered.
