In this paper, the analytical method of analysing the dynamic response of a protective wall subjected to the blast loadings is presented. Based on the deformation observations and analyses, the wall is treated as a shear-flexural plate, wherein the deformations in two orthogonal directions are assumed to be dominated by shear and flexure, respectively. The governing equation is derived, and the method of the blast response analysis is proposed. For a soil protective wall, the numerical results, including dynamic characteristics, structural response, and pressure-impulse (P-I) diagram are given based on the proposed shear-flexural plate model.
