In the present investigation, the behavior of ultra-high strength concrete (UHSC) beams containing different reinforcement ratio and stirrups was investigated. The concrete was successfully prepared from Egyptian local materials. Series of cubes and cylinders were prepared to examine the compressive and splitting strengths of the UHSC at different ages. Eight reinforced beams have been prepared and tested at 28 days. The outcomes indicated that the compressive strength ratio between cylinders

... d cubes samples are 90%, 87% and 85% at 7,28, and 56 days respectively, while the ratio between tensile strength to compressive strength is 38.5% and 36.6% at 7 and 28 days respectively. Furthermore, the beams test outcomes were presented and discussed as deflection, ultimate loads, cracking, failure modes and ductility.
