SHEAR STRENGTH OF SIMPLY SUPPORTED PRESTRESSED CONCRETE BEAMS HAVING WEB REINFORCEMENT

摘要

Tests were made on 24 simply supported, post- tensioned, end-anchored, prestressed concrete beams with and without web reinforce-ment. All of the beams were rectangular in cross section with over-all dimensions 6 inches by 12 inches by 10 feet-0 inch and were reinforced with straight wires bonded throughout their entire length. The beams were loaded at the third points on a 9-foot span. The variables included concrete strength, percentage of longitudinal steel, prestress in the steel, and percent of web reinforcement.
