Structural Design of Steel Roof Trusses for the Magnum Opus General Hospital Project, Manado

This article describes the planning of steel roof truss structure in the Magnum Opus Manado General Hospital construction project. This study aims to design a steel roof truss, plan the profile and size of the profile purlins and horses, the diameter of the track, the diameter of the wind ties, plan the connection and gusset plate, also analyze the output/results of structural strength calculations on steel roof trusses. The research method used is to plan and analyze the structure with the help of autocad software to design, loads are calculated manually, and also use SAP 2000 software to analyze the calculation results of the steel roof truss structure. From this study, the calculation results obtained which states that the planning of steel roof truss structure using light Lip channels gording profile measuring 200.75.20.3, 2, trekstang using iron diameter 12 mm, wind ties using iron diameter 19 mm, Double Angle easel profile measuring 2L.90.90.7 (used on rootstock, upright stems, and diagonal stems), 2L.90.90.13 (used on the upper diagonal rods), and the calculation of Bolt connections as many as 3 bolts in each rod, which have been calculated to be strong, safe, and also sturdy in withstanding the loads that work on the roof frame
