Author / Penulis: Edi Supriyanto Email: edisupriyanto@gmail.com Website: Neurostruct Engineering WhatsApp: Hubungi Kami Abstract The evolution of canopy construction has shifted significantly towards modern cold-formed steel (CFS) systems, driven by the need for rapid assembly, precision, and high structural resilience. Traditional on-site fabrication often suffers from human error and material waste. This paper investigates the implementation of modern prefabrication methodologies, CAD/CAM integration, and advanced mechanical fastening systems in CFS canopy construction. By analyzing structural deflection and shear capacities of modern self-drilling screws, this study provides a comprehensive framework for optimizing lightweight roofing systems in high-exposure environments such as Bali. Part 1: English Version (Academic/Scopus Style) 1. Introduction The utilization of cold-formed steel in modern civil engineering has transcended basic roofing applications. Modern canopy systems now demand high aesthetic value coupled with rigorous structural integrity. The paradigm shift from manual, on-site cutting to computer-aided prefabrication ensures millimeter-level precision, significantly reducing construction time while enhancing the overall load-bearing capacity of the structural nodes. 2. CAD/CAM Integration and Deflection Analysis Modern CFS canopy systems rely heavily on structural analysis software to optimize the cross-sectional profiles before fabrication. A critical serviceability limit state in modern canopies is the control of deflection under uniform loads (e.g., wind and heavy rainfall). For a simply supported principal truss or beam subjected to a uniformly distributed load ($w$), the maximum deflection ($\delta_{max}$) at the mid-span is mathematically modeled as: $$\delta_{max} = \frac{5 \cdot w \cdot L^4}{384 \cdot E \cdot I}$$ Where: $\delta_{max}$ = Maximum deflection (mm) $w$ = Uniformly distributed load along the span (N/mm) $L$ = Unbraced length of the span (mm) $E$ = Modulus of elasticity of the cold-formed steel (typically $2.0 \times 10^5$ MPa) $I$ = Moment of inertia of the optimized cross-section ($mm^4$) In modern engineering protocols, the calculated $\delta_{max}$ must be strictly confined within the allowable limits (e.g., $L/240$) to prevent aesthetic degradation and ensure the proper drainage of rainwater, mitigating the risk of ponding loads. 3. Advanced Fastening Mechanisms Modern CFS structures eliminate the uncertainties of traditional welding by employing high-tensile structural self-drilling screws (SDS). The structural integrity of the entire canopy network is contingent upon the shear and pull-out resistance of these localized nodes. The nominal shear strength ($V_n$) of a single screw connection, assuming the failure occurs in the screw shank rather than the steel sheet, is calculated by: $$V_n = 0.6 \cdot F_{uv} \cdot A_v$$ Where: $V_n$ = Nominal shear capacity of the fastener (N) $F_{uv}$ = Ultimate tensile strength of the screw material (MPa) $A_v$ = Effective cross-sectional area of the unthreaded screw shank subjected to shear ($mm^2$) Modern construction mandates the use of Class 3 or Class 4 anti-corrosive screws to match the lifespan of the AZ-coated steel members. 4.

Pendahuluan Konstruksi kanopi baja ringan di Bali kini telah beralih ke sistem modern yang jauh lebih canggih. Selamat tinggal pada pemotongan manual di lapangan yang membuang banyak material dan rentan terhadap kesalahan manusia (human error). Sistem modern memanfaatkan teknologi prapabrikasi (prefabrication) dan perangkat lunak komputer untuk mendesain dan memotong baja ringan dengan presisi milimeter, menghasilkan kanopi yang estetik, rapi, dan memiliki akurasi struktural tingkat tinggi. 2. Analisis Teknis Lendutan dan Sistem Sambungan Pintar Salah satu keunggulan sistem modern adalah kemampuannya menghitung lendutan (defleksi) struktur sebelum kanopi dipasang. Untuk memastikan kanopi tidak melengkung ke bawah saat menahan beban air hujan lebat, insinyur menggunakan perhitungan defleksi maksimum: $$\delta_{max} = \frac{5 \cdot w \cdot L^4}{384 \cdot E \cdot I}$$ Selain itu, sistem modern menggunakan teknik sambungan mekanis tingkat lanjut dengan sekrup baja ringan struktural bermutu tinggi. Kekuatan geser sambungan antar profil kanal C sangat bergantung pada spesifikasi baut yang dirumuskan secara teknis sebagai: $$V_n = 0.6 \cdot F_{uv} \cdot A_v$$ Rumus ini menjamin bahwa setiap titik pertemuan rangka atap memiliki kekuatan menahan gaya geser dari beban angin kencang tanpa mengalami keruntuhan (shear failure). 3.
