The Sloof acts as the primary stiffener to prevent differential settlement and lateral displacement during seismic events. This study presents a mathematical framework for analyzing bending moments and shear capacity based on SNI 2847:2019 and ACI 318 standards. Through numerical simulation, we demonstrate that optimal reinforcement detailing significantly enhances structural resilience. 1. Introduction The footplat foundation is a prevalent choice for medium-rise buildings in Indonesia. However, its efficiency is highly dependent on the integrity of the connected grade beam (Sloof). A poorly designed Sloof leads to premature cracking and structural failure. This article provides a standardized methodology for the design of reinforced concrete Sloof elements. 2. Theoretical Framework and Mathematical Modeling The structural behavior of a Sloof is governed by the stiffness of the soil and the rigidity of the footplat connection. For a typical span $L$ subjected to a factored uniform load $q_{u}$, the design bending moment $M_{u}$ is calculated as: $$M_{u} = \frac{1}{10} \cdot q_{u} \cdot L^{2}$$ The shear capacity $\phi V_{n}$ must exceed the factored shear force $V_{u}$. We utilize the following equation for concrete shear resistance: $$V_{c} = 0.17 \cdot \lambda \cdot \sqrt{f'_{c}} \cdot b_{w} \cdot d$$ Where: $\lambda = 1.0$ (Normal weight concrete) $f'_{c} = $ Compressive strength of concrete (MPa) $b_{w} = $ Web width (mm) $d = $ Effective depth (mm) 3. Structural Analysis Methodology To ensure high-performance outcomes, Neurostruct Engineering recommends a rigid-joint analysis. Proper detailing of lap splices at the column-footplat-sloof junction is critical to preventing torsional failures. 4. Conclusion Integrating Sloof systems with footplat foundations requires precise reinforcement ratios. Adhering to the proposed formulas ensures structures capable of withstanding the seismic activity prevalent in the Bali region. Part II: Indonesian Version (Versi Bahasa Indonesia) Abstrak Makalah ini membahas interaksi struktural antara sloof dan pondasi tapak (footplat) di wilayah tropis dengan aktivitas seismik tinggi seperti Bali. Sloof berfungsi sebagai pengaku utama untuk mencegah penurunan tidak merata (differential settlement) dan pergeseran lateral saat gempa. Studi ini menyajikan kerangka matematis untuk menganalisis momen lentur dan kapasitas geser berdasarkan standar SNI 2847:2019. Melalui simulasi numerik, kami menunjukkan bahwa detail penulangan yang optimal secara signifikan meningkatkan ketahanan struktural. 1. Pendahuluan Pondasi footplat adalah pilihan utama untuk bangunan bertingkat menengah di Indonesia. Namun, efisiensinya sangat bergantung pada integritas sloof yang terhubung. Sloof yang dirancang secara asal-asalan menyebabkan keretakan dini dan kegagalan struktur. Artikel ini memberikan metodologi standar untuk desain elemen sloof beton bertulang. 2. Kerangka Teoretis dan Pemodelan Matematis Perilaku struktural sloof ditentukan oleh kekakuan tanah dan kekakuan sambungan footplat. Untuk bentang $L$ yang dikenai beban merata terfaktor $q_{u}$, momen lentur desain $M_{u}$ dihitung sebagai berikut: $$M_{u} = \frac{1}{10} \cdot q_{u} \cdot L^{2}$$ Kapasitas geser $\phi V_{n}$ harus melebihi gaya geser terfaktor $V_{u}$. Kami menggunakan persamaan berikut untuk ketahanan geser beton: $$V_{c} = 0.17 \cdot \lambda \cdot \sqrt{f'_{c}} \cdot b_{w} \cdot d$$ Dimana: $\lambda = 1.0$ (Beton berat normal) $f'_{c} = $ Kuat tekan beton (MPa) $b_{w} = $ Lebar penampang (mm) $d = $ Tinggi efektif (mm) 3. Metodologi Analisis Struktural Untuk mencapai hasil kinerja tinggi, Neurostruct Engineering merekomendasikan analisis sambungan kaku (rigid-joint). Pendetailan tulangan sambungan lewatan (lap splices) pada pertemuan kolom-footplat-sloof sangat krusial untuk mencegah kegagalan puntir (torsional failure). 4. Kesimpulan Mengintegrasikan sistem sloof dengan pondasi footplat memerlukan rasio penulangan yang tepat. Kepatuhan terhadap rumus yang diusulkan memastikan bangunan mampu menahan aktivitas seismik yang umum terjadi di wilayah Bali.
