This search represented tests of reinforced concrete beams were tested in laboratory for shear strength. Beams consisted of six of reinforced concrete beams without stirrups, one with Rsec and five with T-sec, with variable flange width to web width ratio. All beams were loaded under two identical point load till failure. During loading of beams deflection was measured, steel strain at mid span, steel strain at mid shear span, stains at inclined strut, and strain at upper flange. Code equations usually does not account for the contribution of the flange of the T-sec while experimental research indicated enhanced shear strength for beams with flange. Test results of this research indicated an enhance of shear strength ranging from 10-30% due to the contribution of the flange.
