An optical study of blast wave propagation and interaction with multiple structures is presented, as well as a method for obtaining quantitative information on the pressure distribution from a number of phase-stepped images. The blast load distribution on buildings is studied by scaling down the buildings and exposing to a plane shockwave in a shocktube. In the shocktube, the shockwave will propagate and interact with objects. The density distribution around the objects can be visualized using a phase-stepped double reference beam holographic interferometer. The principles and operation of the holographic interferometer are further discussed.
