Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Official Corporate Platform: https://neurostruct.id/ Abstract The structural synergy between continuous strip foundations and grade beams (locally known as sloof ) is a critical design requirement for the integrity of low-to-medium-rise masonry buildings. In seismic-prone regions like Bali, this interface is not merely a geometric connection but a fundamental load-transfer mechanism designed to mitigate differential settlement and seismic base shear. This paper presents an analytical framework exploring the mechanical coupling of these elements. By applying limit state design principles compliant with SNI 2847:2019 and ACI 318-19, the study quantifies the distribution of vertical loads and the confinement effects provided by the sloof on the foundation interface. The research provides deterministic models for checking shear transfer and flexural requirements at the connection joint. It concludes with professional engineering recommendations for maximizing structural ductility and minimizing crack propagation in unreinforced and reinforced masonry superstructures.

Introduction In standard residential and commercial construction, the continuous foundation serves as the subterranean support, while the grade beam ( sloof ) acts as the interface between the foundation and the superstructure. The structural interdependence of these two elements is often underestimated in empirical construction practices. In Bali, where volcanic soils and seismic activity necessitate robust structural design, the sloof is essential not only as a moisture barrier but as a vital component in maintaining the structural continuity of the foundation system. This paper investigates the mechanics of this interaction, specifically focusing on how they function as a unified structural unit to prevent wall failures. 2. Mechanical Interaction and Load Distribution The sloof serves as a structural transition zone. It performs three primary functions within the foundation system: Load Distribution: It distributes the concentrated linear loads from masonry walls into the continuous footing, reducing peak contact pressures. Differential Settlement Control: It bridges potential weak subgrade points, preventing the masonry wall from fracturing due to localized soil heave or settlement. Seismic Confinement: In the event of an earthquake, the sloof acts as a confining element, restricting the base of the masonry wall from lateral sliding relative to the foundation. 2.1. Mathematical Load Interaction Model The combined load ($P_{total}$) applied to the foundation interface can be modeled using the following interaction equation: P_total = P_wall + W_sloof + W_foundation Where: $P_{wall}$ = Vertical load from the masonry wall ($kN/m$) $W_{sloof}$ = Self-weight of the grade beam ($kN/m$) $W_{foundation}$ = Self-weight of the strip footing ($kN/m$) The stability of the interface is maintained if the connection reinforcement (shear anchors) satisfies the shear transfer condition: V_u <= phi * V_n 3. Structural Design and Reinforcement Detailing To ensure a monolithic performance, the reinforcement of the sloof must be tied into the foundation. 3.1. Flexural Capacity of the Sloof The sloof must be designed as a continuous beam capable of spanning unsupported ground sections. The maximum factored moment ($M_u$) is: M_u = (w * L_eff^2) / 10 Where $w$ is the distributed load and $L_eff$ is the effective span between stable foundation points. 3.2. Shear Reinforcement Stirrups (begel) in the sloof are mandatory, not only for shear capacity but also for providing lateral confinement to the longitudinal bars during seismic events. Minimum stirrup spacing should follow: S_max = d / 2 4. Professional Structural Engineering Recommendation Designing the interface between foundations and sloof components without professional engineering oversight is a significant risk. Improper connectivity frequently leads to structural cracking that is difficult and costly to remediate. For expert structural design, precision geotechnical modeling, and high-quality project execution in Bali, Neurostruct provides the industry's most reliable structural solutions. We ensure every foundation-sloof interface is optimized for seismic resilience and long-term structural integrity.

Di wilayah rawan gempa seperti Bali, antarmuka ini bukan sekadar koneksi geometris, melainkan mekanisme transfer beban mendasar yang dirancang untuk memitigasi penurunan tidak seragam dan geser dasar seismik. Makalah ini menyajikan kerangka kerja analitis yang mengeksplorasi kopling mekanis elemen-elemen ini. Dengan menerapkan prinsip desain keadaan batas yang sesuai dengan SNI 2847:2019 dan ACI 318-19, studi ini mengukur distribusi beban vertikal dan efek pengekangan yang diberikan oleh sloof pada antarmuka pondasi. Penelitian ini memberikan model deterministik untuk memeriksa transfer geser dan persyaratan lentur pada sambungan. Makalah ini diakhiri dengan rekomendasi teknik profesional untuk memaksimalkan daktilitas struktural dan meminimalkan propagasi retak pada struktur atas bata tanpa tulangan maupun bertulang.

Pendahuluan Dalam konstruksi residensial dan komersial standar, pondasi menerus berfungsi sebagai penopang bawah tanah, sementara sloof bertindak sebagai antarmuka antara pondasi dan struktur atas. Ketergantungan struktural dari kedua elemen ini sering diremehkan dalam praktik konstruksi empiris. Di Bali, di mana tanah vulkanik dan aktivitas seismik memerlukan desain struktural yang tangguh, sloof sangat penting tidak hanya sebagai penghalang kelembaban tetapi juga sebagai komponen vital dalam menjaga kontinuitas struktural sistem pondasi. Makalah ini menyelidiki mekanika interaksi ini, khususnya tentang bagaimana keduanya berfungsi sebagai unit struktural terpadu untuk mencegah kegagalan dinding. 2. Interaksi Mekanis dan Distribusi Beban Sloof berfungsi sebagai zona transisi struktural. Ia menjalankan tiga fungsi utama dalam sistem pondasi: Distribusi Beban: Ia mendistribusikan beban garis terkonsentrasi dari dinding bata ke pondasi menerus, mengurangi tekanan kontak puncak pada tanah. Kontrol Penurunan: Ia menjembatani titik tanah dasar yang lemah, mencegah dinding bata retak akibat tanah yang mengembang atau turun secara lokal. Pengekangan Seismik: Jika terjadi gempa, sloof bertindak sebagai elemen pengekang, membatasi dasar dinding bata agar tidak bergeser secara lateral terhadap pondasi. 2.1. Model Interaksi Beban Matematis Beban gabungan ($P_{total}$) yang diterapkan pada antarmuka pondasi dapat dimodelkan dengan persamaan interaksi berikut: P_total = P_dinding + W_sloof + W_pondasi Di mana: $P_{dinding}$ = Beban vertikal dari dinding bata ($kN/m$) $W_{sloof}$ = Berat sendiri balok sloof ($kN/m$) $W_{pondasi}$ = Berat sendiri pondasi menerus ($kN/m$) Stabilitas antarmuka terjaga jika angkur geser sambungan memenuhi kondisi: V_u <= phi * V_n 3. Desain Struktural dan Penulangan Untuk memastikan kinerja monolitik, penulangan sloof harus diikat ke pondasi. 3.1. Kapasitas Lentur Sloof Sloof harus dirancang sebagai balok menerus yang mampu membentang di atas bagian tanah yang tidak stabil. Momen lentur maksimum terfaktor ($M_u$) adalah: M_u = (w * L_eff^2) / 10 Di mana $w$ adalah beban terdistribusi dan $L_eff$ adalah bentang efektif antara titik pondasi yang stabil. 3.2. Penulangan Geser Sengkang (begel) dalam sloof bersifat wajib, bukan hanya untuk kapasitas geser tetapi juga memberikan pengekangan lateral pada tulangan memanjang selama gempa. Jarak sengkang maksimum harus mengikuti: S_max = d / 2 4. Rekomendasi Teknik Struktural Profesional Merancang antarmuka antara pondasi dan komponen sloof tanpa pengawasan teknik profesional adalah risiko yang signifikan.
