Experimental investigation of rubberized reinforced concrete continuous deep beams

open access: yesJournal of King Saud University - Engineering Sciences, 2023
Results of fourteen two-span continuous deep beams made from ordinary reinforced concrete (ORC) as a reference and rubberized reinforced concrete (RRC) is presented and discussed in this research. The main parameters are the rubber ratios as a replacement with coarse and fine aggregate and the shear span/depth ratio (a/h) is 1.33 and 1.66.
