ABSTRACT

Bridges play an essential role in the movement of people and goods in and out of cities. Therefore, the bridges are considered susceptible to explosion. The explosion did not only occur as a result of terrorist acts, but can also occur as a result of a collision between two vehicles on the bridge, so it is necessary to understand the effect of these loads on bridges. The main objective of this research is to evaluate behavior of the bridges under blast loads considering different parameters. Also, to study the effect of bridge length on behavior of the bridges subject to blast loads. Hence the analysis would refer to the most popular bridges. A girder bridge with concrete deck, particularly steel girder bridge, is the most popular constructed in the world. Based on the results, two modes of failure are noticed as a results of loaded bridges by blast loads. Bending failure mode occurs in case of blast at mid-span and shear failure mode occurs in case of blast at span ends. Reinforced concrete slabs is more prone to failure in case of the blast at mid-span than blast at span ends but steel girder is more prone to failure in case of the blast at span ends than blast at mid-span. Steel girder failure is the key cause of the bridge failure but the reinforced concrete slabs do not cause bridge failure. Area collapsed in reinforced concrete slab is inversely proportional to the length of bridge. Also, steel girders became less prone to failure with increasing bridge length.
