Dynamic Shear Strength of Reinforced Concrete BEAMS. Part II
A series of reinforced concrete beams was tested to study shear and diagonal tension in beams under dynamic load. The tests constitute the second phase of a continuing program to determine criteria for the minimum amount of web reinforcement required for developing the ultimate flexural resistance of beams, and to determine the difference between these criteria for static and dynamic loading. The primary objectives of this Part II series of tests were (1) to determine the minimum amount of web reinforcement necessary to force flexural failures; (2) to confirm, under uniformly distributed loads, a formula for shear resistance recommended by a joint committee of the American Concrete Institute (ACl) and the American Society of Civil Engineers (ASCE), which is based on the analysis of data from tests with concentrated loads; (3) to confirm the coefficients suggested in Part I of this program for the dynamic increase in shearing strength; and (4) to study the influence of stirrup arrangement and type of loading on the location of the critical diagonal tension crack. Fifteen beams were tested, eight loaded dynamically and seven statically. Each beam was simply supported and all loads were uniformly distributed. Twelve beams contained web reinforcement in the region of the critical section, and three had none there. Major variables were type of loading (static and dynamic), magnitude of dynamic load, and stirrup spacing.
