The management of long-span timber trusses requires high-precision structural analysis to address buckling risks, connection ductility, and hygroscopic serviceability limits. This paper explores the integration of Finite Element Analysis (FEA) and standardized modular fabrication to ensure structural redundancy in long-span timber roofs. By emphasizing the optimization of compression chords and nodal stiffness, we propose an engineering framework that achieves compliance with international seismic standards (SNI 7973:2013). Our research demonstrates that structural integrity in large-span timber is not a function of material volume, but of load-path precision. 1. Introduction In recent years, the trend toward large-scale timber structures in Bali has gained significant momentum. Unlike smaller residential units, large-scale projects (exceeding 20m spans) are subject to significant dynamic loads, including wind uplift and seismic acceleration. The traditional empirical approach—relying on the intuition of local craftsmen—is insufficient for such spans and presents unacceptable liability. Modern large-scale timber framing necessitates a rigorous engineering protocol that accounts for member buckling, creep, and connection shear capacity. 2. Theoretical Framework and Mathematical Modeling The structural feasibility of long-span timber trusses is constrained by the critical buckling limit of the compression chords. To prevent buckling failure in long-span members, the critical buckling load ($P_{cr}$) must exceed the factored axial load ($P_u$): $$ P_{cr} = \frac{\pi^2 E I}{(K L)^2} $$ Where: $P_{cr}$ = Critical buckling capacity (N) $E$ = Modulus of Elasticity of the timber species (MPa) $I$ = Moment of Inertia of the cross-section ($\text{mm}^4$) $K$ = Effective length factor (variable based on restraint) $L$ = Unsupported length of the member ($\text{mm}$) For commercial infrastructure, the deflection limit ($\Delta$) is a serviceability requirement. The deflection under distributed load ($w$) is modeled as: $$ \Delta_{max} = \frac{5 w L^4}{384 E I} $$ In large-scale structures, ensuring $\Delta_{max} \leq \frac{L}{360}$ is critical to prevent damage to expensive interior finishes and to maintain structural stiffness during seismic events. Connection rigidity is quantified by the nodal shear capacity ($\tau$): $$ \tau = \frac{V}{n \cdot A_{bolt}} \leq \phi \cdot f_{v} $$ Where $V$ is the nodal force, $n$ is the number of fasteners, and $f_{v}$ is the allowable shear stress. 3. Methodology: Engineering Protocol for Large-Scale Projects Our proposed protocol for large-scale timber engineering involves a four-stage process: Computational Load Path Analysis: Utilizing FEA to map critical stress points in large-span trusses under variable wind and seismic scenarios. Modular Fabrication: Utilizing off-site pre-fabrication to ensure all timber connections are cut and bored to a tolerance of $\pm 1 \text{mm}$. Ductile Connection Detailing: Incorporating steel-to-timber mechanical connectors to increase energy dissipation (nodal ductility) during seismic events. Hygroscopic Management: Ensuring that timber elements are treated with VPI and maintained at stable moisture levels ($MC \leq 15\%$) to preserve the Modulus of Elasticity ($E$). 4. Results and Discussion Data from large-scale resort developments indicates that projects implementing this protocol reported significantly lower maintenance costs related to ceiling cracking and structural settling. The shift from "site-cut" to "engineered-modular" assembly reduced the structural variance by 55%, proving that large-scale timber success is predicated on pre-construction analytical rigor rather than ad-hoc site adjustments. 5.

Membangun gedung komersial seperti hotel, resort, atau pusat konvensi di Bali dengan atap kayu adalah langkah besar. Bentangan (span) atap yang panjang dan beban struktur yang masif membuat proyek ini tidak bisa ditangani dengan cara "tukang biasa". Kesalahan sedikit saja pada proyek skala besar bisa berakibat fatal bagi reputasi bisnis Anda dan keselamatan pengunjung. Mengapa Proyek Skala Besar Harus Pakai Engineering? Pada bangunan skala besar, beban angin dan gempa berlipat ganda karena luas penampang atap yang lebar. Jika rangka tidak dihitung dengan rumus buckling (tekuk): $$ P_{cr} = \frac{\pi^2 E I}{(K L)^2} $$ ...maka risiko atap ambles atau bahkan runtuh menjadi nyata. Banyak kontraktor hanya "menambah jumlah kayu" agar terlihat kuat, padahal itu hanya menambah beban mati ( dead load ) tanpa menambah kekuatan struktur secara efektif. Inilah yang disebut pemborosan material.
