CRACKING AND SHEAR STRENGTH OF BEAMS WITH PRESTRESSED WEB REINFORCEMENT

A programme of tests was carried out on 28 prestressed concrete beams with various combinations of prestressed web reinforcement and stirrups of mild steel or high strength deformed steel. The results are used to derive a formula to obtain the approximate width of inclined cracks and to discuss the calculation of the ultimate shear of beams with vertical prestress with particular reference to cp 110:1972. Prestressing part of the web reinforcement was found to increase both the inclined cracking shear and the ultimate shear. (Author/TRRL)
