PERENCANAAN STRUKTUR TAHAN GEMPA BETON BERTULANG

Perencanaan : Gedung Rusunawa Universitas Teknologi Sumbawa

Abstract

The State Ministry for Public Housing, Housing Provision Work Unit, intends to provide comfortable and safe housing for students, but limited space is an obstacle in itself, the University has a large enough area, so the University of Technology of Sumbawa took the initiative to build Rusunawa (Simple Rental Flats) in the University area. To minimize infrastructure damage and the increase in casualties due to earthquakes, the buildings in the Rusunawa Building, University of Technology, Sumbawa, were designed to use the Special Moment Bearer Frame System (SRPMK). Earthquake loads are designed using the response spectrum which refers to SNI 1726 2019. Modeling and structural analysis uses the 2016 ETABS V.16.2.1 auxiliary program. The design of beam, column, and column beam reinforcement (HBK) is based on SNI 2847 2013. From the calculation results obtained beam B197 with dimensions 30/60 obtained longitudinal / bending reinforcement of left support: upper 5D19, bottom 4D19 and middle 4D16, field reinforcement: top 3D19, bottom 4D19 and middle 4D16, shear reinforcement of plastic hinge area: 4ø10-80 and outer plastic hinge: ø10-120. Column C30 with dimensions of 70/70 and total reinforcement of 28 D25, obtained plastic hinge area shear reinforcement: 4ø12-60, outer area of ​​plastic hinge: 4ø12-140, column joint area: 4ø12-100. Control Design Capacity Σ Mnc ≥ 1.2 Σ Mnb with a value of 4434790293,747 Nmm> 690757290,029 Nmm. From the results of the beam and column planning it can be concluded that: "Strong Column Weak Beam" requirements have been fulfilled. In the bore pile reinforcement with dimensions of 30 cm diameter, 8D16 principal reinforcement and ø10-50 shear reinforcement are obtained.
