Blast Response Tests of Reinforced Concrete Box Structures,
Abstract
Six explosive tests were conducted against reinforced concrete walls to determine the effect of steel reinforcement design on structural response and damage. Reinforcement percentages varying from 0.25 to 2.0 and two reinforcement designs (one with shear stirrups and one with shear dowels) were tested. Test specimens consisted of box structures with 32.5-cm-thick walls. Cased-explosive charges were detonated on the ground near one of the walls of the box. Test structures were instrumented to record blast-pressure loading, steel strains, wall deflection, in-structure acceleration, and concrete-spall velocities. Damage to the walls (similar for all tests, differing only in severity) consisted of a region near the bottom center where the concrete on the wall interior spalled and cracked coupled with a flexural-type response. The loading of the walls was more severe than predicted and the majority of the structural damage was due to spalling. (Author)
