Abstract
The spirit of preserving heritage buildings as they originally became a big challenge during design analysis, ensuring they remain in their original state without damaging the construction process. The objective of this research was to maintain the authenticity of the structure. Roof covering, strengthening and detailing the roof by analyzing the structure on the roof's strength, stability, and deflection with Indonesian code 1729-2015 based on the American Steel concept. Analysis of dead loads, live loads, and the wind load, because only the roof was on the 3rd floor and the roof slope is 30o. The case study method was carried out with surveys and secondary data results from the investigation consultant in 2016. The analysis results of two truss members' roof, 2L 70.70, need to be replaced with a double profile 2L 80.80, bolt connections with the provision that steel profiles, bolts, and rust anchors were replaced. Analysis of the 3-dimensional roof structure with software by calculating the compressive wind load of 75.82 kg/ m2 and the suction wind load of 57.37 kg/m2 according to the wind speed of 40 m/s. Conclusion Steel roof truss meets strength stability and retains the original structure shape, accessories, roof, and tile roof.
