Rahasia Sloof Beton Standar SNI Agar Rumah Tidak Retak di Bali: Panduan Lengkap Tukang & Insinyur Author: edisupriyanto@gmail.com Segment 1: English Version (IEEE/Elsevier International Paper Style) Abstract The reinforced concrete tie beam, locally referred to as "Sloof," serves as a critical horizontal structural element that redistributes loads from walls to the foundation and ensures uniform settlement. This paper investigates the adherence of tie beam construction to the SNI 2847:2019 (Requirements for Structural Concrete). The study evaluates the impact of longitudinal reinforcement ratios and stirrup spacing on the seismic performance of residential buildings in high-seismicity regions like Bali. Results indicate that compliance with SNI standards significantly reduces the risk of shear failure during tectonic events. 1. Introduction In the hierarchy of building structures, the sloof acts as the primary connector between the substructure and the superstructure. Its main function is to mitigate differential settlement and resist lateral loads. In Indonesia, particularly in the Bali seismic zone, the design of sloof must strictly follow the ductility requirements outlined in SNI 2847:2019 and SNI 1726:2019. 2. Design Methodology and Material Standards According to SNI, the minimum compressive strength ($f'_c$) for structural concrete should be no less than 17 MPa for residential buildings, though 25 MPa is recommended for better durability. 2.1. Flexural Strength Calculation The nominal moment capacity ($M_n$) of the tie beam section is calculated as follows: $$M_n = A_s \cdot f_y \cdot \left( d - \frac{a}{2} \right)$$ Where: $A_s$ = Area of longitudinal tensile reinforcement $f_y$ = Yield strength of steel reinforcement $d$ = Effective depth of the beam $a = \frac{A_s \cdot f_y}{0.85 \cdot f'_c \cdot b}$ (Depth of equivalent stress block) 2.2. Shear Reinforcement (Stirrups) To prevent diagonal tension failure, the shear capacity ($V_n$) must satisfy: $$V_u \leq \phi (V_c + V_s)$$ Where $V_c$ is the shear strength provided by concrete: $$V_c = 0.17 \cdot \lambda \cdot \sqrt{f'_c} \cdot b_w \cdot d$$ 3. Seismic Detailing for Bali Region Bali’s proximity to the subduction zone necessitates "Special Moment Resisting Frames" (SMRF) detailing. This includes specific stirrup hooking at $135^\circ$ angles and controlled spacing ($s$) near the supports, typically not exceeding $d/4$ or 100 mm to ensure core confinement. 4.

Makalah ini membahas kepatuhan konstruksi sloof terhadap SNI 2847:2019 . Studi ini mengevaluasi pengaruh rasio tulangan longitudinal dan jarak sengkang terhadap kinerja seismik bangunan di Bali. Hasil menunjukkan bahwa kepatuhan terhadap standar SNI secara signifikan mengurangi risiko kegagalan geser saat terjadi gempa bumi. 1. Pendahuluan: Mengapa Sloof SNI Sangat Penting? Sloof bukan sekadar balok di atas tanah. Di wilayah seperti Bali yang rawan gempa, sloof berfungsi sebagai pengikat ( tie beam ) yang menjaga seluruh kolom bangunan tetap menyatu saat tanah bergoyang. Tanpa sloof yang sesuai standar SNI, bangunan sangat rentan mengalami retak rambut hingga keruntuhan total akibat penurunan pondasi yang tidak merata ( differential settlement ). 2. Standar Penulangan Menurut SNI 2847:2019 SNI mengatur secara ketat mengenai jarak tulangan dan diameter besi. Untuk bangunan rumah tinggal, diameter tulangan pokok minimal biasanya adalah 10 mm atau 12 mm dengan sengkang (begel) minimal diameter 8 mm. 2.1. Perhitungan Luas Tulangan Minimum Luas tulangan minimum ($A_{s,min}$) untuk mencegah retak lentur dihitung dengan: $$A_{s,min} = \frac{0.25 \cdot \sqrt{f'_c}}{f_y} \cdot b_w \cdot d$$ Serta tidak boleh kurang dari: $$A_{s,min} = \frac{1.4}{f_y} \cdot b_w \cdot d$$ 2.2. Pentingnya Selimut Beton Untuk sloof yang bersentuhan langsung dengan tanah, SNI mewajibkan ketebalan selimut beton ( concrete cover ) minimal 75 mm jika dicor langsung di atas tanah, atau 50 mm jika menggunakan lantai kerja. Hal ini krusial di Bali untuk mencegah korosi tulangan akibat uap air laut atau kelembapan tanah tropis. 3. Kesalahan Umum di Lapangan Banyak tukang di lapangan hanya menggunakan sengkang dengan sudut $90^\circ$. Padahal, untuk wilayah gempa, sengkang harus ditekuk $135^\circ$ masuk ke dalam inti beton. Tanpa tekukan ini, sengkang akan "terbuka" saat gempa, menyebabkan beton hancur seketika. 4.
