ANALYSIS OF THE SUPERSTRUCTURE DESIGN OF THE EMPLOYEE DORMITORY BUILDING AT SYUKURAN AMINUDDIN AMIR AIRPORT, LUWUK, CENTRAL SULAWESI

Abstract

Syukuran Aminuddin Amir Airport in Luwuk, Central Sulawesi, has experienced an increase in the number of personnel,
while the availability of staff housing only meets a portion of the total demand. To support comfort and work
productivity, a two-story staff dormitory building is designed as a small-scale vertical residence that is earthquake
resistant. This final project designs the upper structure of the staff dormitory building using the Special Moment
Resisting Frame (SMRF) system in accordance with the provisions of SNI 2847:2019, SNI 1726:2019, and SNI
1727:2020. Structural analysis is carried out for dead loads, live loads, and equivalent static earthquake loads based on
the seismic parameters of Banggai Regency. The structural modeling is conducted in three-dimensional form using
SAP2000 v22 software. The design results show that the main structural elements consist of primary beams measuring
30×40 cm, secondary beams 25×35 cm, columns 40×40 cm, and one-way slabs with a thickness of 14 cm. Longitudinal
and shear reinforcement are designed based on the results of internal force analysis and anchorage length as per the SNI
standards. Section capacity evaluation shows that all elements meet the strength and ductility requirements. The
estimated construction cost for the upper structure is Rp940,800,000.00 (nine hundred forty million eight hundred
thousand rupiahs). This SMRF structural design is declared safe against the planned loads and can serve as a reference
for vertical residential planning in earthquake-prone areas.
