| Abstract | ||
| An experimental program was conducted to investigate the shear behavior of simply supported deep beams made of reinforced lightweight concrete (LWC), both with and without web openings. The test program consisted of four simply supported, deep beams made of reinforced concrete. The dimensions and placement of the openings were the primary variables. The results of the experiment show that adding web openings to the load path lowers the ultimate shear strength of LWC simply supported deep beams. More precisely, the findings indicated that web openings measuring 20% of the total web height resulted in a decrease of about 15% in the maximum shear strength when compared to a beam without any openings of the same type. Web openings that had a height equivalent to 40% of the overall web height resulted in a significantly larger decrease in the ultimate shear strength, roughly 62%, compared to a beam without similar openings. This result can be utilized to guide the development of reinforced concrete simply supported deep beams in the future, specifically in relation to the dimensions and placement of web openings. | ||
