Effect of Blast Wave on Structures

In recent years, explosive devices are the weapon of choices for the majority of terrorist attack that not only affects the life of human being but also the structure resistance and physical integrity. Bomb explosion near the building can cause such amount of pressure and produces a large amount of heat resulting a high strain loading on building and its elements. Such a high strain loading can cause catastrophic damage on buildings external and internal structural frame, collapsing of walls, blowing out large expense of windows and shutting down of critical life safety systemsThe response of steel frame building subjected to blast loading was examined by calculating blast load manually using a procedure and applying on joints. Response of steel column subjected to amount of pressure exerted by different charge weights and at different standoff distance and progressive energy collapse of steel column is examined using Ansys Explicit dynamic and Ansys Autodyn. Concrete wall subjected to blast loading is modeled in Finite Element package Ansys and then analyzed in Autodyn with and without steel plate to study the impact of blast loading
