ALTERNATIF PERENCANAAN STRUKTUR ATAS MENGGUNAKAN SRPM DAN DINDING GESER

Studi Kasus : Gedung Apartemen Begawan Malang

Abstract

Malang City is a city of education as well as a city of tourism. Therefore, apartment construction is one of the steps to support community needs. The construction of the Begawan Apartment is intended for students who study around the building and also for tourists visiting Malang City and Batu City. To minimize infrastructure damage and the increase in casualties due to earthquakes, the buildings in the Begawan Apartement at Tlogomas Malang, were designed to use the Dual System, Special Moment Resisting Frame System (SMRF) and Shear Walls. From the calculation results obtained beam B7 at Story 6 with dimensions 40/60 obtained longitudinal / bending reinforcement of left support: upper 14D22, bottom 8D22 and middle 4D22, field reinforcement: top 6D22, bottom 6D22 and middle 4D22, shear reinforcement of plastic hinge area: 4ø12-80 and outer plastic hinge: 4ø12-160. Column C4 at Story 1 with dimensions of 80/80 and total reinforcement of 16 D25, obtained plastic hinge area shear reinforcement: 5ø12-90, outer area of plastic hinge: 5ø12-120, column joint area: 5ø12-90. Control Design Capacity Σ Mnc ≥ 1.2 Σ Mnb with a value of 2205.400 KNm > 1953.461 KNm, it can be concluded that: "Strong Column Weak Beam" requirements have been fulfilled. At the beam-column joint, reinforcement for the vertical confinement are 16D25 and for the horizontal confinement are 5ø12 – 12 layers. The planned shear walls component is at Pier 1 with dimensions of 400 x 6550 with boundary elements as far as 1000 mm from the extreme compressive fiber. The transverse reinforcement of the boundary elements is 6ø12-80. Longitudinal reinforcement is attached to all sections of the shear wall, are 100D25. Transverse reinforcement in the area of the shear wall body for the X and Y directions of the plastic hinge region 2ø12-80, the outer area of the plastic hinge 2ø12-120 and in the column joint area 2ø12-80.
