In this paper, the interaction between a blast wave and an array of cylindrical objects (pipe or vessel) has been numerically investigated to evaluate blast load distribution around the objects. It was found that the interaction leads to a blast focusing within the gap between two adjacent pipes, and that the focused overpressure may exceed a fully reflected overpressure. This paper examines the effects of a combination of the arrangement of pipes (diameter, gap distance) and incident blast wave characteristic parameters (positive phase duration) on the focusing phenomena and the resultant blast load distribution.
