THE INVESTIGATION OF DEEP REINFORCED CONCRETE BEAMS UNDER STATIC AND DYNAMIC LOADING. VOL. II STRENGTH AND BEHAVIOR IN SHEAR
Abstract
Thirty-five beams were tested, 13 statically and 22 dynamically, to determine their strength and behavior in shear; to determine if failure under a dynamic load was different from that under a static load; and to evaluate the effectiveness of web reinforcement in moderately deep beams. All beams tested, both statically and dynamically, exhibited arch action prior to failure. Three types of failures are described for both tests: flexure, shear, and flexure-shear. Web reinforcement in the beams tested both ways contributed little toward an increase in strength or a change in behavior and mode of failure, except for generally reducing the ultimate deflections. The static strength at flexural yielding in these moderately deep beams could be predicted reasonably well by the conventional straight line theory. The ultimate static flexural strength could be predicted by the standard ultimate strength procedure provided an increased value of the limiting concrete strain equal to 0.008 is used at failure.
