Abstract:

An explosion within or nearby a building can cause catastrophic damage to the building. The blast explosion is due to pressure or vehicle bomb or quarry blasting. Lifeline structures like buildings, bridges, pipelines, industrial plants, dams etc. plays an important role in the economy of our country so that they have to be protected from these explosions. Because of the nonlinear behavior of the material, the dynamic response of the structures under blast loading is complex to analyze. Explosion will generate large dynamic loads which would be greater than original loads for which the structure is designed and analyzed. Normally, the conventional structures are not designed to resist blast loads because its magnitude is very higher than the normal design loads. So the engineers are seeking solutions to potential blast situations. Column is the most important load bearing structure in a building. So it is necessary to study the effect of blast loading on columns. This study focuses to enhance the understanding of the behavior of columns when subjected to blast load and also the effect of various parameters like standoff distance, aspect ratio etc. are discussed.
