Title: Behavior and Strength in Shear of Beams and Frames Without Web Reinforcement
Author(s): Roger Diaz De Cossio and Chester P. Siess
Publication: Journal Proceedings
Appears on pages(s): 695-736
Abstract:forty-nine simply supported beams and Q4 frame members were tested under several different types of loading. These included: two-point loads, midspan concentrated loads, uniform load, and axial load. The frame members and 18 simple supported beams were tested under uniform load. Ten of the beams under midspan concentrated loads were tested with an axial load of QO kips. Special emphasis was placed on the effects of axial and uniform loads on shear strength and behavior of the members. Other variables were concrete strength, steel percentage, and span length. The test results are given, discussed, and correlated. The use of the inclined tension cracking load as a measure of the useful shear strength of the members is advocated, and a procedure is given for its determination.
