BLAST LOAD TESTS ON POST-TENSIONED CONCRETE BEAMS

Abstract

Four types of post-tensioned prestressed concrete beams with straight unbonded bars were tested under static and blast loading to study their behavior. The tests showed that the response of prestressed beams can be predicted by a onedegree of freedom system provided the correct damping and resistance functions are known. The logarithmic decrement of the beams was about 0.05 to 0.28, which permitted negative deflections to develop under short-duration loading.A recommended dynamic design procedure is given. (Author)
