Abstract

Abstract

Column is the main bearing member in bridge. It is the premise for analyzing the dynamic response of the bridge under blast loading to study the distribution law of blast load acted on bridge columns. Circular sectional bridge column has been selected as the research object, and the corresponding finite element models have been built by using the LS-DYNA software. When the height of burst is less than 0.3 times of the column height, the scaled distance is 0.5−2.1 m/kg^1/3 and the column diameter is 0.15−1 m, the distributions of the blast loading impulse along column height and cross-section direction are obtained through numerical simulations. The influential parameters, e.g., the explosive equivalent, height of burst, explosion distance and sectional diameter, have been considered. It is derived that, along the column height, when the contact burst and the height of burst is 0.1 times of the column height, the blast loading impulse on the column front surface approximately follows the " Single linear” distribution. When the height of burst is 0.2 and 0.3 times of the column height, the blast loading impulse approximately follows the " Double linear” distribution. Along the cross-section direction, the ratio of the average net blast loading impulse to the blast impulse on the column front surface is a constant. Furthermore, the resultant net blast loading impulse of bridge column has been obtained, which can put some theoretical basis for blast-resistant analysis and design of bridge columns.
