Abstract
The ability of reinforced beams to carry loads is determined by two factors, namely the ability to carry bending loads due to moments and the ability to carry shear forces. Previous tests have proven that 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 reinforced concrete beams with a cross-section size of 175x350mm with a length of 3000mm. main reinforcement 3D16mm, stirrup reinforcement 8mm, 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 a stirrup spacing of 10 cm (BN10) then the beams are given cavities using plastic bottles with a length of 3240mm (12 bottles), cavity height: 180mm/3 bottles. 2 hollow concrete beams were made with variations in the spacing of stirrups, 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 research aims 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.
