THE INVESTIGATION OF SHEAR BEHAVIOR OF R.C. BEAMS MADE OF SELF COMPACTING CONCERTE WITH HIGH STRENGTH
Self-Compacting Concrete has a unique characteristic which flows to place and around obstruction under its own weight to fill the formwork completely and its self compact without any segregation.This article outlines the effect of parameters such as stirrups spacing and variations of concrete strength on the behavior of reinforced concrete beams made of Self Compacting Concrete. In this study 9 beams were tested which 3 of these beams were made of ordinary concrete with the strength of 40 Mpa and 6 of the beams were made of SCC with high strength concrete having the strengths of 60 and 80 Mp. For each of these groups the stirrups were placed by the distances of 80, 100 and 133mm. The tested beams were simply supported and were loaded by two concentrated load.It was found that using SCC with high strength in comparison with normal concrete will increase the stiffness and ultimate hear strength of beams and will reduce deflections. The cracking pattern at ultimate load of Normal and High strength self compacting concrete beams were the same, also the reduction in the distance of stirrups in shear span was the reason to increase ductility and ultimate load in all beams.
