Pengaruh Diameter Sengkang Terhadap Kuat Geser Balok Dengan Variasi Diameter Tulangan Sengkang 6mm, 8 Mm Dan 10 Mm

Abstract

Concrete is a construction material that is important and the most dominant is needed on the building structure, to determine the strength of normal concrete structures or modification needs to be a study with a wide range of variations, including the influence of the diameter of stirrups on shear strength of the beam. This study discusses the effect of stirrups to shear beam diameter by using test objects such as concrete beams with stirrups diameter variation 6mm, 8mm and 10mm, the concrete strength used was 26.73 MPa with beam dimensions of 150mm x 160mm x 300mm methods used in this study is a method of testing laboratory which aims to investigate the causal relationship between each other and comparing the results. The test results concluded stirrup diameter changes effect the shear strength of the beam resulting in a decrease of the load on the beam to strong shear stirrups BG.TR.3 10mm diameter, for a distance of reinforcement stirrups owned ≤ BG.TR.3 minimum shear reinforcement spacing requirements. Variations diameter beam shear reinforcement stirrups to give the effect of 74.85% in the test specimen to specimen BG.TR.1 BG.TR.2. and the optimal value of the shear strength test to variations of reinforcement stirrup diameter is 10mm diameter with a shear strength value of 0.8968 kN.m.
