Test Evaluation Of Blast Protective Double Roof
RCC Structure

Abstract
A RCC double roof structure with an energy absorption layer in-between and
having a hand packed boulder overburden of 1.5m designed to withstand the
blast effects of a close in detonation was test analysed for the blast protective
effectiveness. The paper discusses the behaviour of this structure subjected to
intense shock loads generated by detonating HE cylindrical charges at various
stand offs from boulder overburden and also at different depth of bursts in the
bouilder media.The stresses developed at different points of the structure were
monitored using load cells, strain gauges and displacement transducers.The paper
also discusses the crack pattern and the damage mechanism of the structure.The
role of energy dissipation layer in the two roof structure is highlighted.
