In this work, a solution for the response of a gravity loaded wall element subjected to blast load is developed. The solution is based on the extension of the conventional single-degree-of-freedom (SDOF) method for the dynamic response analysis of structural components. The gravity axial load is applied on the top of the wall with an equivalent mass. Both the bending and shear failure criteria are included in the solution when the axial load effect is accounted for. The solution is validated with finite element analyses and some experimental data to explore potential of the solution for general engineering evaluations of the dynamic response of a gravity loaded wall subjected to the blast load.
