Abstract

One way that can be used to place openings on parallel shear walls is to place the coupling beams between the two shear walls. Coupling beam is a structural element that connects the structural wall to provide additional stiffness and energy dissipation. In many cases, the geometric limit produces a coupling beam with a high ratio and a high net width. Thus, the beams can be controlled by shear and is losing stiffness and strength at the time of the earthquake. Specifications coupling beams planning to wear fas: 0.5, mix design using mixed planning methods in the laboratory. In the research done do the manufacture of test object of this coupling beam using reinforcement reinforcement with dimension ratio 2,75; 3.00; 3.25. This test results in maximum load, deflection, shear stiffness, and shear strength. Coupling beam with a maximum load test result of 100 kN for the coupling without reinforcing diagonal beam, and the beam is coupled with a strengthening reinforcement diagonal with a 3.25 ratio of 100 kN the same results with the coupling beam without strengthening reinforcement diagonal, the coupling beam ratio of 113.33 kN 3.00 increased by 2.90% from the coupling beam without reinforcement diagonal, the coupling beam ratio of 146.67 kN 2.75 an increase of 10.14% from the coupling beam without reinforcement Diagonal, the resulting deflection of 0.061 m (without reinforcement) And on the coupling beam with diagonal reinforcement ratio 3.25 of 0.059 m decreased 0.88% of the coupling beam without reinforcement diagonal, the 0.0009 m 0.059 m coupling beam decreased by 0.89% of the coupling beam without Diagonal reinforcement strength, and at a ratio of 3.25 of 0.58 m decreased by 1.07% of the coupling without diagonal reinforcement, the resulting shear stiffness of 4.93 kN / m (without reinforcement) And on the coupling beam with diagonal reinforcement ratio of 3.25 of 5.55 kN / m increased 2.68% of the coupling beam without reinforcement diagonal reinforcement, the 3.79 kN / m beam ratio of 3.00 increased by 3.71% of the coupling beam without diagonal reinforcement, and at a 3.25 ratio of 6.86 kN / m increased by 8.35% of the coupling without diagonal reinforcement, the resulting shear strength of 333.33 kN / m (Without reinforcement) And on the coupling beam with the 3.25 reinforcement reinforcement ratio of 362.32 kN / m increased by 1.91% of the coupling beam without reinforcement diagonal reinforcement, the 3.00 beam ratio of 377,78 kN / m increased by 2.93% of the beam coupling without strengthening reinforcement diagonal, and at a ratio of 3.25 at 444.44 kN / m increased by 7.32% from the coupling beam without reinforcement diagonal. Then testing the collapse pattern of the coupling beam without diagonal reinforcement as well as with the same diagonal reinforcement, which is preceded by crack in the middle of the span, then followed by sliding crack in the pedestal area. On coupling beams without reinforcement diagonal collapse that happened was a drag diagonally. While on the coupling beam with reinforcement reinforcement reinforcement that occurred is shear collapse, can be seen crack sliding occurs very dominant.
