Abstract
The strength of a reinforced beam in carrying loads is determined by two factors, namely; (1) the ability to bear bending loads due to moments, and (2) the ability to bear shear forces due to shear forces. Tests carried out by the research team have previously proven that with certain cavity formations, the flexural capacity of hollow concrete beams is the same as that of normal reinforced concrete beams. This study aims to obtain the effect of shear force on the shear capacity of hollow reinforced concrete beams. In this study used hollow reinforced concrete beams with a cross-section size of 175x350mm and a length of 3000mm. main reinforcement 3D16mm, stirrup reinforcement D8mm, spacing 150mm, material quality f'c = 25 MPa and fy = 400 MPa as control beams. (BN15). Next, blocks are made with the same size and material quality with the stirrup spacing of 10 cm (BN10), then given a cavity using a plastic bottle with a length of 3240mm (12 bottles), cavity height: 180mm/3 bottles. 2 hollow concrete beams were made with a variation of stirrup spacing, namely 150mm (BR15) and 100mm (BR10). The load distribution was regulated by a 2-point load system, namely (a): 50 cm from each position, so the value a/d = 1.6; thus, according to the Nawy theory, a shear failure will be obtained. The loading is given gradually and gradually increased until failure occurs in the beam. The aim of the research is to obtain the shear capacity of hollow reinforced concrete beams. Thus, the ability of hollow reinforced concrete beams to carry loads can be relied upon.
