الملخص | Qatar is known by its harsh corrosive environment that is represented by high periodical humidity, and dust accompanied by temperature fluctuation. Also, geographically Qatar is considered a peninsula, this in turn makes it highly susceptible to seawater spray which contains high chloride contents. Recently, basalt fiber reinforced polymer (BFRP) bars are among the most investigated types of anti-corrosive advanced composites in structures. Accordingly, the present paper aims at examining the efficiency of sand coated basalt fiber reinforced polymer (SBFRP) bars and ribbed glass (GFRP) stirrups in resisting shear stresses in large scale basalt fiber reinforced concrete (BFRC) beams. The effect of the reinforcement ratio ρf (2.054 ρfb and 4.53 ρfb where ρfb is the balanced reinforcement ratio) on the shear capacity of the tested beams was investigated. Results revealed an increase in the ultimate load capacity by 48% when the reinforcement ratio was increased from 2.054 ρfb to 4.53 ρfb. Also, it was clearly noticed that the beam stiffness has significantly enhanced at higher reinforcement ratio, especially after the onset of first flexural crack. |
