DOWNLOAD EBOOKReinforced concrete deep beams are vital structural members serving as load transferring elements. The behavior of reinforced concrete deep beams is complex. Nonlinear distribution of strain and stress must be considered. Prior to 1999, ACI 318 Codes included an empirical design equation for reinforced concrete deep beams. Since 2002, the strut and tie model and nonlinear analysis have been required. However, both methods have disadvantages of complexity or lack of transparency. The objective of this study is to produce a simple, reliable design equation for reinforced concrete deep beams. A nonlinear finite element program, ATENA, was used for analyzing and predicting the behavior of concrete and reinforced concrete structures. First, applicability of ATENA was verified by developing the computer models of simply supported and two span continuous deep beams based on Birrcher's tests of simply supported deep beams. Tests by Rogowsky and Macgregor and by Ashour are the basis for the models of continuous two span deep beams. Those tests were selected because the researchers reported adequate details of the experimental program and on specimen behavior. Then a series of simply supported and two span continuous deep beam models were developed based on the details and geometry of Birrcher's beams. The computer models were used to investigate the following parameters: the compressive strength of concrete, shear span to depth ratios, longitudinal reinforcement ratios, web reinforcement, effect of member depth, and loading conditions. Finally, a proposed design equation for shear strength of reinforced concrete deep beams was derived based on the observed the behavior of reinforced concrete deep beam tests, the results of the analytical study, and a plastic truss model. The proposed equations were in good agreement with test values and provide an alternate approach to current design procedures for deep beams.

DOWNLOAD EBOOKBehavioral 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).

DOWNLOAD EBOOKLarge-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.
