Author: Edi Supriyanto Email: edisupriyanto@gmail.com Website: https://neurostruct.id/ Consultation: https://wa.me/6281338718071/ Part I: English Version (Academic Paper) Abstract The grade beam (Sloof) acts as a pivotal structural component in the interface between foundation systems and the superstructure. Its primary function is to tie foundation elements together, distribute loads, and prevent differential settlement. This paper provides a comprehensive review of grade beam integration across three foundation typologies: shallow spread footings (footplat), deep pile caps, and traditional river stone masonry. By utilizing structural mechanics, we analyze the transfer of seismic forces and bending moments. The study emphasizes the design compliance with SNI 2847:2019 and ACI 318, providing a mathematical framework for shear and flexural design to ensure long-term structural serviceability in high-seismicity regions such as Bali. 1. Introduction The grade beam is often misunderstood as a non-structural element. In reality, it is the primary horizontal stabilizer in the building's skeleton. In seismic zones, the grade beam must be engineered to resist both gravitational floor loads and lateral seismic induced displacements. This research establishes the design criteria for grade beams integrated with varied soil-bearing capacities. 2. Mechanical Analysis of Grade Beam Interaction 2.1 Load Distribution The interaction between the grade beam and the foundation involves vertical soil reaction and horizontal seismic resistance. The factored bending moment ($M_{u}$) for a grade beam spanning two foundation elements is: $$ M_{u} = \frac{1}{10} \cdot q_{u} \cdot L^{2} $$ Where: $q_{u}$ = Factored uniform load from the wall or floor above (kN/m) $L$ = Clear span between foundation centers (m) 2.2 Differential Settlement Resistance To mitigate the impact of soil consolidation, the grade beam must exhibit sufficient stiffness. The required Moment of Inertia ($I$) to limit deflection ($\Delta$) is given by: $$ I = \frac{q \cdot L^{4}}{384 \cdot E \cdot \Delta_{limit}} $$ Where: $q$ = Service load (kN/m) $E$ = Modulus of elasticity of concrete (MPa) $\Delta_{limit}$ = Permissible settlement ($L/500$) 3. Foundation-Specific Detailing Protocols Footplat Foundation: The grade beam acts as a tie, preventing rotation of the footing. Reinforcement must be anchored using 90-degree hooks into the pedestal. Pile Cap: Grade beams provide lateral bracing to piles, reducing the effective unbraced length. River Stone Masonry: In regions like Bali, the grade beam is critical to prevent masonry cracking due to foundation settling. 4. Conclusion Integrating grade beams with foundation systems is essential for seismic resilience. Engineers must treat grade beams as critical load-bearing members, applying rigorous reinforcement detailing to ensure monolithic structural behavior. Part II: Indonesian Version (Bahasa Indonesia) Abstrak Balok pondasi atau sloof berfungsi sebagai komponen struktural krusial di antarmuka antara sistem pondasi dan struktur atas. Fungsi utamanya adalah mengikat elemen pondasi, mendistribusikan beban, dan mencegah penurunan tidak merata ( differential settlement ). Makalah ini memberikan tinjauan komprehensif integrasi balok pondasi pada tiga tipologi pondasi: pondasi tapak ( footplat ), pile cap , dan pondasi batu kali tradisional. Dengan memanfaatkan mekanika struktural, kami menganalisis transfer gaya seismik dan momen lentur. Studi ini menekankan kepatuhan desain terhadap SNI 2847:2019 dan ACI 318, menyediakan kerangka matematis untuk desain geser dan lentur guna memastikan kelayakan layanan struktur jangka panjang di wilayah seismik tinggi seperti Bali. 1. Pendahuluan Balok pondasi sering disalahpahami sebagai elemen non-struktural. Padahal, ia adalah penstabil horizontal utama dalam rangka bangunan. Di zona seismik, balok pondasi harus direkayasa untuk menahan beban lantai gravitasi dan perpindahan lateral akibat gempa. Penelitian ini menetapkan kriteria desain untuk balok pondasi yang diintegrasikan dengan berbagai kapasitas dukung tanah. 2. Analisis Mekanis Interaksi Balok Pondasi 2.1 Distribusi Beban Interaksi antara balok pondasi dan pondasi melibatkan reaksi tanah vertikal dan ketahanan seismik horizontal. Momen lentur terfaktor ($M_{u}$) untuk balok pondasi yang membentang di antara dua elemen pondasi adalah: $$ M_{u} = \frac{1}{10} \cdot q_{u} \cdot L^{2} $$ Dimana: $q_{u}$ = Beban merata terfaktor dari dinding atau lantai di atasnya (kN/m) $L$ = Bentang bersih antar pusat pondasi (m) 2.2 Ketahanan Terhadap Penurunan Tidak Merata Untuk memitigasi dampak konsolidasi tanah, balok pondasi harus menunjukkan kekakuan yang memadai. Momen Inersia ($I$) yang diperlukan untuk membatasi lendutan ($\Delta$) diberikan oleh: $$ I = \frac{q \cdot L^{4}}{384 \cdot E \cdot \Delta_{limit}} $$ Dimana: $q$ = Beban layanan (kN/m) $E$ = Modulus elastisitas beton (MPa) $\Delta_{limit}$ = Penurunan yang diizinkan ($L/500$) 3. Protokol Pendetailan Berdasarkan Jenis Pondasi Pondasi Footplat: Balok pondasi bertindak sebagai pengikat, mencegah rotasi footing . Tulangan harus diangkur menggunakan kait 90 derajat ke dalam pedestal. Pile Cap: Balok pondasi memberikan pengaku lateral pada tiang, mengurangi panjang tekuk efektif. Pondasi Batu Kali: Di wilayah seperti Bali, balok pondasi sangat kritis untuk mencegah keretakan pasangan bata akibat penurunan pondasi. 4. Kesimpulan Mengintegrasikan balok pondasi dengan sistem pondasi sangat penting untuk ketahanan seismik. Insinyur harus memperlakukan balok pondasi sebagai elemen pemikul beban kritis, menerapkan pendetailan penulangan yang ketat untuk memastikan perilaku struktur monolitik.
