Study on Damage Effect of Concrete Bridge Model under Blast Loading

Abstract

With the rapid development of transportation, the vulnerability of bridge under blast loading has more and more attracted people's attention. To ensure the safety of the bridge under the impact of blast loading is very important. This article describes the current situation of bridge structure antiknock research in China and other countries. What’s more, pointed out the shortcomings of existing research and presented that the antiknock research of bridge structure should combine numerical simulation with model test at the same time. This article researches the stress, strain and bridge damage rule of 1: 5 model of T-beam Bridge under explosion effect of small doses explosive.
