COMPARATIVE ANALYSIS OF LIGHT STEEL ROOF FRAMES AND WOODEN ROOF FRAMES BASED ON STRUCTURAL STRENGTH AND CONSTRUCTION COSTS (CASE STUDY: EMERGENCY OPERATIONS CENTER BUILDING AT JUWATA TARAKAN AIRPORT)

Abstract

The Emergency Operations Center (EOC) building is a strategic facility that functions as a coordination and
control center in emergency situations. Its purpose is to design a roof truss structure that meets safety and
structural strength standards in accordance with Indonesian National Standards. The results of modeling
the lightweight steel and wooden roof frames using SAP 200 V22 software show that the lightweight steel
roof frame trusses using CNP 100 x 50 x 20 x
3.2 mm and CNP 50 x 35 x 20 x 2 mm purlins. The wooden roof frame uses Class II meranti wood with
dimensions of 8/12. The lightweight steel frame experienced the largest deflection of 1.754 mm, while the
wooden structure recorded a larger deflection value of 2.137 mm. The ratio of lightweight steel is 0.8, while
wood is 0.312. The cost comparison for lightweight steel results in a total budget of Rp66,452,530.00, while
wood reaches Rp70,431,061.
