This study aims to design the roof structure of a material warehouse for PT. Uxxx using a steel structure
with the Load and Resistance Factor Design (LRFD) method based on SNI 1729:2020. The research
focuses on determining the appropriate steel profile dimensions for the roof frame, selecting the roof
covering material, and producing detailed design drawings. The structural analysis considers vertical
loads (dead load, live load, and rain load) and horizontal loads (wind and seismic loads) in accordance
with SNI 1727:2020 and SNI 1726:2019. The analysis was conducted using STAAD.Pro software to
evaluate the structural performance under various load combinations. The results show that the
proposed steel profiles Light Lip Channel 150x65x20x3.2 for purlins, WF 300x150x6.5x9 for rafters,
and WF 350x175x7x11 for columns meet the strength and serviceability requirements. Additionally,
UPVC (Unplasticized Polyvinyl Chloride) is recommended as the roof covering due to its durability,
weather resistance, thermal insulation, and lightweight properties, which align with the structural and
functional needs of the warehouse. This research contributes to the field of civil engineering by
demonstrating the application of modern steel design methods (LRFD) in industrial buildings. The
findings provide practical solutions for efficient, safe, and economical roof structures, ensuring optimal
performance under operational and environmental conditions.
