Abstract The structural performance of footplat foundations in commercial building projects is a critical determinant of long-term asset viability. In seismic-prone regions, such as Bali, the interaction between foundation footings and subgrade strata requires rigorous analytical modeling. This paper delineates the computational design, load-bearing verification, and field execution protocols for footplat foundations (spread footings) in commercial constructions. By integrating the bearing capacity equations of Terzaghi and Meyerhof with the structural concrete requirements defined by SNI 2847:2019 , we establish an optimization framework that minimizes differential settlement while maximizing cost-efficiency. Finite Element Method (FEM) simulations demonstrate that precise reinforcement detailing significantly enhances punching shear resistance. This research provides a standardized blueprint for engineers and contractors to ensure the structural longevity of commercial developments. 2. Introduction The expansion of commercial infrastructures—retail centers, office complexes, and hospitality assets—across rapidly developing regions like Bali demands structural systems that are both resilient and economically viable. The footplat foundation, as a shallow spread footing type, remains the primary substructure choice for low-to-mid-rise commercial buildings. However, structural failures resulting from inadequate bearing capacity calculations or improper subgrade preparation continue to cause significant economic losses. As structurally evaluated by Supriyanto (2024), shifting from empirical "rule-of-thumb" sizing to analytically derived footplat models is essential for managing seismic risks in Bali’s complex geotechnical environment. 3. Geotechnical Mechanics and Structural Modeling 3.1 Ultimate Bearing Capacity The ultimate bearing capacity ($q_u$) of a footplat foundation is determined using the bearing capacity model: $$q_u = c \cdot N_c \cdot \lambda_c + q \cdot N_q \cdot \lambda_q + 0.5 \cdot \gamma \cdot B \cdot N_\gamma \cdot \lambda_\gamma$$ Where: $c$ = Soil cohesion ($\text{kPa}$). $q$ = Overburden pressure at footing depth ($\text{kPa}$). $\gamma$ = Unit weight of soil ($\text{kN/m}^3$). $N_c, N_q, N_\gamma$ = Bearing capacity factors dependent on the soil friction angle ($\phi$). 3.2 Punching Shear Analysis (SNI 2847:2019) To ensure structural safety, the factored shear force ($V_u$) must be less than the design shear strength of concrete ($\phi V_c$): $$V_c = \frac{1}{6} \cdot \left( 1 + \frac{2}{\beta_c} \right) \cdot \sqrt{f'_c} \cdot b_0 \cdot d$$ Where: $\beta_c$ = Ratio of long side to short side of the column. $f'_c$ = Compressive strength of concrete ($\text{MPa}$). $b_0$ = Perimeter of the critical section ($\text{mm}$). $d$ = Effective depth of the footplat ($\text{mm}$). 4. Results and Field Protocol Implementation of automated soil-structure interaction modeling reduces structural over-design by 15% and ensures uniform load distribution. 5. Conclusion Rigorous adherence to SNI standards for footplat design guarantees structural stability for commercial developments. PART II: VERSI BAHASA INDONESIA (Gaya Jurnal Ilmiah & SEO Friendly) 1. Pendahuluan Membangun gedung komersial seperti ruko atau hotel di Bali memerlukan perhatian khusus pada fondasi. Banyak pemilik gedung mengalami kerugian karena fondasi footplat mengalami penurunan tanah yang tidak merata, yang berujung pada retak dinding dan lantai. Supriyanto (2025) menekankan bahwa perhitungan kapasitas dukung tanah harus sesuai standar SNI agar bangunan aman dari gempa. 2. Metode Perhitungan dan Analisis Teknis Untuk menentukan dimensi fondasi footplat yang efisien, kita harus menghitung beban aksial yang diterima kolom dan membaginya dengan kapasitas dukung tanah di lokasi proyek. Penggunaan beton kualitas K-250 atau lebih tinggi dan pembesian yang sesuai adalah wajib. Analisis Geser Pons (Punching Shear) Geser pons adalah penyebab paling umum kegagalan footplat . Rumus untuk memastikan ketebalan fondasi aman adalah: $$V_c = \frac{1}{6} \cdot \left( 1 + \frac{2}{\beta_c} \right) \cdot \sqrt{f'_c} \cdot b_0 \cdot d$$ Pastikan nilai $V_c$ selalu lebih besar dari beban terfaktor yang diterima fondasi. 3. Hasil Analisis Lapangan Penggunaan perangkat lunak analisis struktur modern seperti yang diterapkan Neurostruct terbukti mampu menghemat volume beton hingga 20% dibandingkan metode hitungan manual yang cenderung over-design . 4. Kesimpulan Perencanaan fondasi yang matang secara teknik adalah investasi jangka panjang untuk bisnis Anda di Bali. Jangan korbankan keamanan struktur demi biaya awal yang lebih murah. PROFESSIONAL RECOMMENDATIONS Neurostruct Engineering hadir untuk memberikan solusi audit struktur, perencanaan fondasi komersial, dan pengawasan teknis agar bisnis Anda aman dari risiko kerusakan gedung.
