Abstract

"Wide reinforced concrete beams have been used in buildings to reduce reinforcement congestion and floor heights for required headroom. The beaming most of these cases is wider than that of the supporting columns. Consequently their shear capacity might be effected and differ from that of conventional beams. This project report presents the test results of four wide beam specimens in which their shear performances were studied. The influence of the support widths (100% of the beam width), the arrangement of flexural reinforcement across the beam width, and the presence of shear reinforcement in the forms of third specimens consist of concrete with steel plate and control beam conventional beam were investigated. The test setup was made similar for all the specimens, one pointed load were on the beam width, the load put at distance column (300mm*300mm) from the center of support, therefore, the specimen control failed in diagonal tension shear. But other specimens failed in flexural corporation. The results showed that wide beam with plate has no effect on the shear strength of concrete and the influence of concentrating the flexural reinforcement within the support width has no significant effect on the shear strength of concrete.
