摘要：Deep beam is the reinforced concrete structure, which has loads like normal beam, but has a comparatively high rate / width of a large, with clean span of Ln equal to or less than four times the overall member height (h) or twice effectively depth beam (2d ) from the face of support with concentrated loading. Strut and Tie Model (STM) is a method used to find the balance between load and reaction forces in the concrete and steel. Redesign on Rusunawa beams using deep beam structure that consists of, beam 0.9 mx0,3m with length 6.8 m that loaded of concentrated loading and deep beam 1.3 mx0, 4m by 4.2 meters long that uniformly distributed loading. quality of concrete is used 25 Mpa and the quality of Steel 350 Mpa From the results of planning by using Strut and Tie Model (STM), obtained main flexure reinforcement of 6.8 meters is 4D19 for tensile bar and 5D19 for assembling bar. and Ø8- 160mm for horizontal and vertical stirrups. As for the deep beam spans 4.2 meters, obtained flexure reinforcement is 5D20 for tensile and assembling bar and Ø8 - 220.2 mm for horizontal and vertical stirrups. Keywords: Deep beam, Strut and Tie method
