Shear Strength Prediction of High Performance Reinforced Concrete Deep Beams with Stirrups by ANSYS

Abstract

The present paper is a theoretical analyses of three dimensional (3D) finite element (FE) model to predicate the shear stress, shear strain, load deflection and crack propagation of sixteen high performance reinforced concrete deep beams (HPRCDB) with stirrups by ANSYS (v14). The main variables considered were; vertical shear stress (p_vf_y), ranging from 1.27 to 7.46MPa, horizontal shear stress (p_vf_y), ranging from 2.38 to 5.30 MPa and vertical and horizontal (combination) shear stress (p_vf_y), ranging from (1.27+2.38 to 7.46+5.30) MPa, Three types of concrete were used based on the compressive strength; Normal Strength Concrete, (NSC), 43MPa, High Strength Concrete, (HSC), 62.5MPa, and High Performance Concrete, (HPC), more than 100MPa.Results obtained by ANSYS were compared with the experimental results in order to verify the accuracy of the finite element model. The theoretical results of the FE models show good agreement with the taken experimental data, in both linear and nonlinear behaviors ranges up to failure. The effect of each parameter were discussed and compared with the experimental works.
