Description
Summary:The effect of the development of reinforcement strut on the performance of discontinuity regions in concrete deep beams was tested through an experimental program. Four reinforced concrete deep beams with two different designs reinforcement (conventionally reinforcement and strut reinforcement) and with various amounts of web reinforcement tested to select the optimum design of deep beams. The geometry and main reinforcement were constant for all specimens. Measurements of cracking patterns, recording the strain in the axis and edges of the struts by (DIC) technique, and analyses of load-displacement at mid-span of investigated concrete deep beams. The data results indicated that the capacity of the deep beam with reinforcement strut higher than the control deep beam with traditional reinforcement and with less displacement. A control deep beam was failed by diagonal tension stresses in the struts, not present in the reinforcement strut specimens. Where the compression stresses were found in the axis of the strut.
