Analysis of a blast-loaded protective wall for bridge columns

Abstract

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.

A Predictive Model for Damage Assessment and Deformation in Blast Walls Resulted by Hydrocarbon Explosions

“…An analytical method based on plate theory for blast wall design [4] is rarely used in the literature since the results of those studies cannot be used directly as a design code. However, linear and nonlinear finite elements have been used significantly (for example, [5,6]).…”
