Nonlinear Finite Element Analysis of Reinforced Concrete Haunched Beams Without Shear Reinforcement Under Static Shear Load

In the current paper, the verification of simply supported reinforced concrete (haunched and prismatic) beams has been done for different haunched angles. These beams have tested without shear reinforcement previously. These beams have tested by applying a concentrated static load at a mid-span. The verification has been done by comparing the results of nonlinear finite element analysis method by using ANSYS (Mechanical APDL) software with the experimental work results, where the load–deflection curves were obtained for both (FEA and experimental). The verification has done for three beams; one was as a prismatic beam and two more as a haunched beam with different haunched angles (α). The results obtained from ANSYS were in agreement with the experimental results, where the load–deflection curves of ANSYS results and experimental results were matching for all beams. The ANSYS results confirm the different behaviour of RCHBs with respect to prismatic beam which have been observed in an experimental work also. This paper shows the strength of ANSYS software in modelling and analysis.
