Abstract

The objective of this investigation is to study the efficiency of adding polypropylene fiber for improving the properties of concrete and punching shear strength of reinforced concrete flat slab subjected to elevated temperatures . Twelve panels were tested in this study. The models simulate the region of negative bending moment around an internal column supporting a flat plate roofs. One group of slab specimens were tested in room temperatures and three groups specimens were test with different degree of elevated temperatures. The test loads were applied incrementally up to the ultimate carrying capacity. Deformations, crack patterns and ultimate loads were recorded.
