Abstrait:

This paper presents a study to simulate the performance of steel-plate composite bridge under various blasting loads. The multi-Euler domain method based on the fully coupled Lagrange and Euler models is adopted for the structural analysis of explosion process with the commercial software Autodyn. Due to the difference of material characteristics and space distribution between the concrete and steel part, the most adverse position is estimated to be above and below detonation. A remarkable difference between these two explosive denotations for steel-concrete composite bridge is noted, and the failure mode above denotation is the damage of local concrete deck, with the compression mode near the denotation point showing a standard trigonometric curve. The failure mode below denotation includes damage of steel girders and concrete failure near junction.
