Blast Performance of Prestressed Concrete Panels
For accidental or terrorism-related blast loading, typical structural design practice allows substantial inelastic deflections and rotations to be considered for reinforced concrete and steel flexural members, provided that the members are well-detailed and the structure is not required to remain operational after a blast event. Such practices have been based on a wide body of experimental test data, largely compiled by military engineers. Flexural members made of prestressed concrete, conversely, are not permitted to undergo large inelastic deformations when exposed to blast loads. One reason for this disparity in code provisions is a lack of experimental test data for prestressed concrete elements under blast loading. Four prestressed concrete panels were tested under the simulated blast loading of a shock tube as part of an experimental program at The University of Texas at Austin. Post- and pre-tensioned panels both with and without polypropylene fiber reinforcement were tested; the focus of this paper is the response of the two normal-concrete panels.
