In seismic-prone regions, the splicing of longitudinal bars represents a potential failure point. This paper evaluates two primary splicing techniques: traditional lap splicing and mechanical couplers. We analyze the stress transfer efficiency, constructability, and structural performance under cyclic loading. The research demonstrates that mechanical couplers significantly enhance ductility and reduce congestion in reinforcement cages, providing a superior solution for high-density structural detailing. Standardized guidelines according to SNI 2847:2019 and ACI 318 are provided to ensure engineering compliance. Keywords — Reinforcement Splicing, Lap Splice, Mechanical Couplers, Column Ductility, Seismic Design, Structural Continuity. 1. Introduction The transition of vertical loads between column tiers relies on the effective splicing of longitudinal reinforcement. Inadequate splicing leads to stress concentration and premature yield. As structural requirements in tropical zones become more stringent, traditional lap splicing often poses challenges in terms of reinforcement congestion and material waste. 2. Splicing Mechanics A. Lap Splice (Traditional) Lap splicing relies on bond stress between concrete and steel. The required lap length ($L_d$) is calculated based on concrete strength and bar diameter: $$L_d = \left( \frac{f_y}{1.1 \cdot \lambda \sqrt{f'_c}} \right) \cdot \alpha \cdot \beta \cdot \gamma \cdot d_b$$ Where: $f_y$ = Yield strength of steel ($MPa$). $f'_c$ = Compressive strength of concrete ($MPa$). $d_b$ = Bar diameter ($mm$). B. Mechanical Couplers Couplers provide a direct path for axial force transfer, independent of concrete bond, offering higher performance in high-stress zones.

Engineering Recommendations For mid-to-high-rise projects, the transition to mechanical couplers is highly recommended to improve concrete flow and seismic performance.

Edi Supriyanto Neurostruct Engineering, Bali, Indonesia Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Website: https://neurostruct.id/ Abstrak — Sambungan tulangan kolom antar lantai adalah titik krusial dalam mentransfer beban vertikal. Artikel ini membandingkan teknik lap splice (sambungan lewatan) dan mechanical coupler (sambungan mekanis) dari sisi kekuatan, kemudahan pengerjaan, dan standar SNI agar struktur gedung Anda memiliki ketahanan gempa yang maksimal. Kata Kunci — Sambungan Tulangan, Lap Splice, Mechanical Coupler, Kolom Beton, Struktur Gedung, SNI 2847. 1. Pendahuluan Banyak kesalahan terjadi saat menyambung tulangan kolom, seperti kurangnya panjang lewatan ( overlap ) atau posisi sambungan yang berada di area sendi plastis. Artikel ini merangkum standar teknis yang benar sesuai SNI 2847:2019. 2. Teknik Sambungan Lap Splice: Teknik tradisional dengan menumpuk tulangan. Rumus panjang lewatan ($L_d$) sangat krusial agar tulangan tidak "tercabut" dari beton. Mechanical Coupler: Sambungan modern menggunakan drat. Lebih kuat, rapi, dan tidak membuat penulangan menumpuk (tidak padat). 3. Analisis Teknis Untuk gedung bertingkat, terutama di wilayah rawan gempa seperti Bali, penggunaan coupler lebih disarankan karena tidak bergantung pada lekatan beton dan memberikan distribusi beban yang lebih linear. 4. Rekomendasi Profesional Jangan biarkan struktur Anda lemah karena sambungan tulangan yang salah. Neurostruct siap membantu supervisi dan perencanaan struktur agar sambungan antar lantai gedung Anda memenuhi standar keamanan tertinggi.
