Book Description
Large-scale static tests were performed on deep reinforced concrete beams. Nominal concrete strengths for all tests varied between 2,500 and 4,000 psi, and intermediate-grade ASTM A 15 reinforcing steel was used. All beams were simply supported. Tests consisted of thirteen test beams of three span-depth ratios, 1.66, 2.67, and 3.62, subjected to a uniformly distributed load. Beams contained longitudinal tensile reinforcing with or without web reinforcing. Both horizontal and vertical web reinforcing were used. Behavior was observed as span-depth ratio and web reinforcing were varied. Numerous modes of failure in shear were observed as beam configuration was varied. Modes of failure transitioned from shear to flexure as span-depth ratio increased and amount and orientation of web reinforcing were varied. Test data were correlated with mathematical models derived in this study and from models developed by others. The mathematical models were used to investigate shear behavior for deep beams. Equations were developed which adequately predict the medium shear behavior of deep beams with web reinforcing. Test data were also correlated with theories developed by others for flexural moment and deflection behavior. Generally, flexural moment behavior was adequately predictable.

Book Description
The contents of this book have been chosen with the following main aims: to review the present coverage of the major design codes and the CIRIA guide, and to explain the fundamental behaviour of deep beams; to provide information on design topics which are inadequately covered by the current codes and design manuals; and to give authoritative revie

Book Description
Behavioral equations were developed for reinforced concrete deep beams, especially in the realm of shear capacity. A series of static and dynamic beam tests was performed to aid in the development of this objective. Static shear behavior equations for deep beams were derived on the lower boundary of reinforced concrete deep beam data represented by research from this report and other research comprising 73 tests. Equations for a total static shear capacity are given which conservatively predict shear capacities of the beam tests considered. (Author).

Book Description
Large-scale dynamic tests were performed on deep reinforced concrete beams. Nominal concrete strengths for all tests varied between 2,000 and 3,500 psi; intermediate-grade ASTM A 15 reinforcing steel was used. All beams were simply supported. Tests were performed on nine beams of three span-depth ratios (1.66, 2.67, and 3.62), subjected to a uniformly distributed dynamic transient load. The beams contained longitudinal tensile reinforcing with or without web reinforcing. Both horizontal and vertical web reinforcement were used. Behavior was observed as the span-depth ratio and web reinforcement were varied. Numerous modes of failure in shear were observed as beam configuration was varied. Modes of failure transitioned from shear to flexure as the span-depth ratio increased and the amount and orientation of web reinforcement were varied. Data were correlated with mathematical models derived in this study and with models developed in static tests. The mathematical models were used to investigate shear behavior for deep beams. Equations were developed which predicted the median shear behavior of deep beams with web reinforcement. Dynamic response prediction models were developed which predicted the measured response of the dynamic test beams. Recommendations are made for further research in the development of improved design criteria for Air Force defense systems. (Author).
