| Abstract: | In this paper, according to the test results of ten partially prestressed concrete and two reinforced concrete rectangular beams with circular openings, the influence of the size and the spacing of opeings, and the amount of reinforcement around openings on shear behaviour is studied. Based on these results, Some recommendations are presented. |
