Title: Shear Strength of Prestressed Beams Without Web Reinforcement
Author(s): R. H. Evans and E. G. Schumacher
Publication: Journal Proceedings
Appears on pages(s): 1621-1642
Abstract:Tests to ultimate failure on 54 simply supported pre- Tests to ultimate failure on 54 simply supported prestressed beams loaded with two symmetrically placed stressed beams loaded with two symmetrically placed concentric loads are reported. Variables included: amount concentric loads are reported. Variables included: amount of longitudinal reinforcement, length of shear span, shape of longitudinal reinforcement, length of shear span, shape of cross section, and method of curing. A study was also of cross section, and method of curing. A study was also made of the mechanism of failure by diagonal cracking. made of the mechanism of failure by diagonal cracking. Distinction is made between beams failing in shear- Distinction is made between beams failing in shear-compression, by diagonal cracking, and failures following compression, by diagonal cracking, and failures following diagonal cracking. Expressions are presented for the three diagonal cracking. Expressions are presented for the three modes of failure. modes of failure.
