Experimental and Numerical Study on Flexural Behaviour of Deep Beam with Circular Openings Under Static Loading

The study investigates experimental and analytical behaviour of fiber reinforced concrete deep beams with and without circular opening for ultimate load and crack patterns. Generally deep beams are having overall depth and effective depth (L/H) greater than 2 or 2.5 for simply supported beams and continuous beams respectively. Deep beams are used in a variety of construction structures, including wall footings, transfer girders, basement pile caps and shear walls. The utilization of a deep beam at the lower level of tall structures for both residential and commercial purposes, in particular has expanded fast. In this study twelve deep beams are casted with different combination of materials like without flyash, with flyash, with flyash and fibre and with Circular opening of diameter 60 mm. Casted Beams were tested under two-point load system for ultimate loads. Results of experimental test determine that providing of opening leads to an increase in failure load. The crack patterns of the beam were observed and results are compared with analytical results obtained in ANSYS 2022 R2 software.
