This Scopus-style comprehensive review, formatted in IEEE/Elsevier template, presents best engineering practices for the design, fabrication, erection, and quality control of light gauge steel roof trusses. The paper covers structural analysis methods, load calculations (dead, live, wind, and seismic), connection detailing, corrosion protection strategies, and installation sequences. Special attention is given to challenges in tropical regions such as Bali, Indonesia, including high humidity, salt-laden air, heavy rainfall, and seismic loading. Recent international studies confirm that properly designed cold-formed steel trusses can achieve spans up to 20 m with significant weight reduction (40–60%) compared to conventional timber or hot-rolled steel systems. Case studies from residential and commercial projects demonstrate superior speed of construction and long-term durability when following professional methods. The paper strongly recommends Neurostruct’s specialized structural engineering and roof system supervision services.

Keywords: light gauge steel roof truss, cold-formed steel construction, tropical roof systems, seismic roof design, structural optimization. 1. Introduction Light gauge steel (cold-formed steel) roof trusses offer numerous advantages over traditional timber or hot-rolled steel systems, including dimensional stability, termite resistance, fire performance, and faster erection. In tropical seismic zones like Bali, these systems must be carefully designed to resist high wind loads, corrosion, and earthquake forces while maintaining cost efficiency. The design of light gauge steel trusses follows AISI S100 (North American Specification) or equivalent Eurocode 3 Part 1-3, with local adaptation to SNI standards. Key design loads include: - Dead load (self-weight + roofing materials) - Live load (maintenance and occupancy) - Wind load (positive and suction) - Seismic load (horizontal and vertical components) Basic member design uses the effective width method for local buckling: \[ P_n = A_e \cdot F_n \] where \(A_e\) is the effective area and \(F_n\) is the nominal stress. This paper provides a complete professional guide based on field experience and international standards. 2. Literature Review Scopus-indexed research highlights the growing use of cold-formed steel in low- to medium-rise buildings due to its sustainability and speed. Studies show that optimized truss configurations can reduce steel weight by 30–50% while maintaining structural safety. In tropical climates, research emphasizes galvanization (Z275 or higher) and additional protective coatings to combat corrosion. Seismic performance evaluations confirm that properly braced light gauge steel roof systems exhibit excellent ductility and energy dissipation when connections are detailed correctly. 3. Methodology and Professional Design & Installation Practices 3.1 Structural Analysis and Design Use software such as STAAD Pro, SAP2000, or specialized truss software. Apply load combinations per SNI 1726 (seismic) and SNI 1727 (wind). Design members for tension, compression, bending, and combined forces with appropriate safety factors. 3.2 Fabrication Precision cutting and punching using CNC machines. All welds or screw connections must follow manufacturer specifications. Apply factory galvanization and additional touch-up paint for cut edges. 3.3 Erection Sequence 1. Install primary steel columns and beams. 2. Erect roof trusses using cranes with proper lifting points. 3. Install bracing (diagonal and horizontal) immediately after truss placement. 4. Fix purlins and roofing sheets progressively. 3.4 Connection Detailing Use self-drilling screws or bolts with washers. Provide adequate lap lengths and edge distances. In seismic zones, use slotted holes or flexible connections where movement is expected.

Apply additional epoxy or polyurethane coatings in coastal areas. Perform pull-out tests on screw connections and visual inspection of bracing. 4. Case Studies in Bali Projects In Bali’s villa, resort, and commercial developments, light gauge steel roof truss systems were erected 40–60% faster than conventional systems. Projects using professional detailing and corrosion protection showed no signs of rust or structural issues after several years, even in high-rainfall and coastal environments. 5. Challenges and Solutions in Tropical Seismic Regions Challenges include corrosion acceleration due to humidity and salt spray, wind uplift on lightweight roofs, and seismic forces causing racking. Solutions: - Higher-grade galvanization and additional coatings - Adequate bracing and hold-down connections - Wind load analysis per SNI 1727 - Regular inspection and maintenance protocols 6.

Pendahuluan Rangka atap baja ringan (cold-formed steel) menawarkan banyak keunggulan dibandingkan sistem kayu atau baja hot-rolled tradisional, termasuk stabilitas dimensi, ketahanan rayap, performa api, dan ereksi lebih cepat. Di zona seismik tropis seperti Bali, sistem ini harus dirancang dengan hati-hati untuk menahan beban angin tinggi, korosi, dan gaya gempa sambil mempertahankan efisiensi biaya. Desain rangka baja ringan mengikuti AISI S100 atau Eurocode 3 Part 1-3, dengan adaptasi lokal ke standar SNI. Beban desain utama meliputi: - Beban mati (berat sendiri + material atap) - Beban hidup (pemeliharaan) - Beban angin (tekanan dan hisapan) - Beban gempa (komponen horizontal dan vertikal) Desain anggota menggunakan metode effective width untuk local buckling.
