| Abstract | ||
| This paper presents an experimental investigation consisting of casting and testing twelve rectangular simply supported reinforced concrete deep beams. Three of the tested beams are made with conventional concrete (CC), three with ultra-high performance concrete (UHPC) and six as hybrid beams of the two concrete (UHPC &CC). UHPC is used in compression in the hybrid beams. The effect of these parameters on the behavior of the test beams included deflection, failure mode, and ultimate loads is investigated. Experimental results generally show that stiffer load-deflection behavior is obtained with the increase of UHPC layer thickness (hR/h) and steel fibers volumetric ratio (Vf) for hybrid beams with UHPC in compression. | ||
