| Popis: | This paper gives the analytical investigation of six reinforced concrete deep beams reinforced with horizontal and vertical web reinforcement. Reinforced concrete deep beams analysis is a complex problem where there is no exact solution. The effect of reinforcement distribution has been studied and compared to experimental investigation and various codes such as ACI 318 and IS 456. A new formula is proposed to define shear strength of deep beams. The codal equations are too traditional for predicting the shear strength of RC deep beams, so an improved and simplified equation was proposed using nonlinear finite element method by ABAQUS. The FE results are compared with experimental results in terms of ultimate loads, displacements, tension stress damage. The proposed shear strength equation predicts 80% of the experimental data in the range of 66–110% of measured shear strength. FE model results accurately predicted. The stress contours suggested high stresses in the path of cracks and low stresses in the uncracked regions. |
