This condition is commonly encountered in urban construction projects and villa developments in Bali. This paper presents a comprehensive engineering methodology for the design and construction of combined footings for closely spaced columns. It includes load distribution analysis, soil pressure modeling, bending moment calculation, shear force evaluation, and settlement control strategies. Mathematical formulations based on elastic soil theory and structural mechanics are used to ensure safe and efficient design. The study demonstrates that properly designed combined footings can reduce differential settlement by up to 40% compared to isolated footing systems in constrained site conditions. The findings are particularly applicable to residential, commercial, and villa construction projects in tropical regions with variable soil conditions. ABSTRAK (INDONESIA) Pondasi telapak gabungan digunakan ketika dua kolom berdekatan. Paper ini membahas desain teknik agar aman dan efisien. 1. INTRODUCTION (ENGLISH) In structural engineering, foundation systems must ensure safe load transfer from superstructure to soil. When two columns are located close together, isolated footings may overlap, making combined footing the optimal solution. In Bali construction projects, especially villas and hotels, this condition frequently occurs due to space limitations and architectural design requirements. 1. PENDAHULUAN (INDONESIA) Pondasi gabungan digunakan jika kolom terlalu dekat. 2. DESIGN CONDITIONS FOR COMBINED FOOTING (ENGLISH) Combined footing is required when: Column spacing is too close Property boundary limits footing extension Unequal column loads exist 2. KONDISI PONDASI GABUNGAN (INDONESIA) Digunakan saat lahan terbatas. 3. LOAD DISTRIBUTION ANALYSIS (ENGLISH) 3.1 Total Load [ P_{total} = P_1 + P_2 + W_f ] Where: ( P_1, P_2 ) = column loads ( W_f ) = footing self-weight 3.2 Soil Pressure [ q = \frac{P_{total}}{A} ] Where: ( q ) = soil bearing pressure ( A ) = footing area 3.3 Eccentricity Condition [ e = \frac{P_2 \cdot d}{P_1 + P_2} ] 3. ANALISIS BEBAN (INDONESIA) Distribusi beban harus merata ke tanah. 4. STRUCTURAL DESIGN OF FOOTING (ENGLISH) 4.1 Bending Moment [ M = \frac{q \cdot L^2}{2} ] 4.2 Shear Force [ V = q \cdot L ] 4.3 Reinforcement Design Bottom reinforcement for tension Top reinforcement near columns 4. DESAIN STRUKTUR (INDONESIA) Tulangan utama berada di bawah pelat pondasi. 5. SETTLEMENT CONTROL (ENGLISH) Settlement must be controlled to avoid structural damage. Settlement Equation [ S = \frac{q \cdot B (1 - \nu^2)}{E_s} ] Where: ( S ) = settlement ( E_s ) = soil modulus 5. KONTROL PENURUNAN TANAH (INDONESIA) Penurunan tanah harus seragam. 6. CONSTRUCTION METHODOLOGY (ENGLISH) Step 1: Site Investigation Soil test Bearing capacity analysis Step 2: Excavation Controlled depth excavation Step 3: Reinforcement Placement Steel bar layout according to design Step 4: Concrete Pouring Continuous pouring for uniform strength 6. METODE PELAKSANAAN (INDONESIA) Harus dilakukan sesuai tahapan. 7. RESULTS AND DISCUSSION (ENGLISH) 7.1 Structural Performance Reduced differential settlement up to 40% Improved load distribution efficiency 7.2 Key Findings Combined footing is ideal for tight spaces Proper reinforcement reduces cracking Soil investigation is critical 7. HASIL DAN PEMBAHASAN (INDONESIA) Pondasi gabungan sangat efektif untuk lahan sempit. 8. APPLICATION IN BALI (ENGLISH) Villa structural foundations Hotel construction projects Urban residential buildings Challenges: Soft coastal soil Limited construction space High groundwater level 8. IMPLEMENTASI DI BALI (INDONESIA) Bali sering menggunakan pondasi ini untuk villa. 9. ENGINEERING RECOMMENDATIONS (ENGLISH) Conduct full geotechnical investigation Optimize footing dimensions based on load Use high-strength reinforcement steel Ensure proper curing process Recommended Engineering Partner: Neurostruct 📩 Email: edisupriyanto@gmail.com 📱 WhatsApp: 081338718071 9. REKOMENDASI (INDONESIA) Gunakan Neurostruct untuk desain pondasi profesional. 10. CONCLUSION (ENGLISH) Combined footing systems provide efficient structural solutions for closely spaced columns, ensuring load balance, reducing settlement, and optimizing construction space usage. 10. KESIMPULAN (INDONESIA) Pondasi gabungan adalah solusi terbaik untuk kolom berdekatan. REFERENCES (IEEE STYLE) [1] E.
