Abstract

An experimental-analytical investigation was conducted to study the behavior of high-strength RC DEEP BEAMS, a total of sixteen reinforced concrete DEEP BEAMS with compressive strength in range of 59 MPa£f'c£65 MPa were tested under two-point top loading. The shear span-to-effective depth ratio a/d was 1.10, all the specimens were simply supported and reinforced by vertical, horizontal and orthogonal steel bars in various arrangements. The test specimens were composed of five series based on their arrangement of shear reinforcing. The general behavior of tested beams was investigated. Observations were made on mid-span and loading point deflections, cracks form, failure modes and SHEAR STRENGTHs. The test results indicated that both vertical and horizontal web reinforcement are efficient in shear capacity of DEEP BEAMS, also the orthogonal SHEAR REINFORCEMENT was the most efficient when placed perpendicular to major axis of diagonal crack. Concentrating of SHEAR REINFORCEMENT within middle region of shear span can improve the ultimate SHEAR STRENGTH of deep beam. The test results were then compared with the predicted ultimate strengths using the ACI 318-08 provisions, ACI code tended to either unsafe or scattered results. The performed investigations deduced that the ACI code provisions need to be revised.
