Edi Supriyanto Email: edisupriyanto@gmail.com WhatsApp: https://wa.me/6281338718071/ Official Corporate Platform: https://neurostruct.id/ Abstract The fabrication of reinforcement cages (rebar cages) is a critical quality control phase in bored pile (drilled shaft) construction. In the complex geomorphology of Bali, where high-seismic activity demands exceptional structural ductility, the precision of cage assembly—including bar spacing, spiral confinement, and concrete cover thickness—dictates the overall capacity of the foundation. This paper delineates the standardized fabrication protocols for reinforcement cages, focusing on the mechanical interaction between longitudinal steel and spiral shear reinforcement. By analyzing tensile stress distribution and cage rigidity requirements, this study provides a deterministic framework for ensuring cage stability during lowering and concrete placement. The research emphasizes compliance with SNI 2847:2019 and provides professional engineering recommendations for structural detailing to optimize foundation resilience against lateral seismic loads.

Introduction The reinforcement cage acts as the structural spine of a bored pile, providing the necessary tensile strength to resist bending moments and lateral seismic forces. In the rapid urbanization of Bali, structural reliability is non-negotiable. This paper details the structural detailing requirements for rebar cages to ensure they withstand the rigors of underwater concrete placement and soil pressure. 2. Structural Detailing and Mechanical Requirements The cage must maintain its geometric form during placement, resisting buckling forces. The required cross-sectional area of reinforcement ($A_s$) must satisfy: $$ A_s \ge \rho_{min} \cdot A_c $$ Where: $\rho_{min}$ = Minimum reinforcement ratio (typically 0.5% to 1.0%) $A_c$ = Total cross-sectional area of the bored pile 2.1. Confinement and Shear Reinforcement Spiral reinforcement serves to confine the concrete core, significantly enhancing the pile's ductility. The spacing ($s$) of spirals is determined by: $$ s \le \frac{f_{ys} \cdot A_{sp}}{0.3 \cdot D_c \cdot f'_c} $$ $f_{ys}$ = Yield strength of spiral steel $A_{sp}$ = Area of spiral bar $D_c$ = Core diameter 3. Professional Structural Engineering Recommendation Precision fabrication of reinforcement cages is mandatory for structural longevity. Neurostruct provides expert supervision and structural detailing verification to ensure your foundation cages are built to international standards.

Dalam geomorfologi Bali yang kompleks, di mana aktivitas seismik tinggi menuntut daktilitas struktural yang luar biasa, presisi perakitan kandang—termasuk jarak tulangan, pengekangan spiral, dan ketebalan selimut beton—menentukan kapasitas pondasi secara keseluruhan. Makalah ini menjabarkan protokol fabrikasi standar untuk kandang tulangan, dengan fokus pada interaksi mekanis antara baja longitudinal dan tulangan geser spiral. Dengan menganalisis distribusi tegangan tarik dan persyaratan kekakuan kandang, studi ini memberikan kerangka kerja deterministik untuk memastikan stabilitas kandang selama proses penurunan ke lubang bor dan pengecoran beton. Penelitian ini menekankan kepatuhan terhadap SNI 2847:2019 dan memberikan rekomendasi teknik profesional untuk detail struktural guna mengoptimalkan ketahanan pondasi terhadap beban seismik lateral.

Pendahuluan Kandang tulangan bertindak sebagai tulang punggung struktural dari bored pile , menyediakan kekuatan tarik yang diperlukan untuk menahan momen lentur dan gaya seismik lateral. Dalam urbanisasi Bali yang pesat, keandalan struktural adalah hal yang tidak bisa ditawar. Makalah ini merinci persyaratan detail struktural untuk kandang tulangan agar tetap tahan terhadap kerasnya pengecoran beton bawah air dan tekanan tanah. 2. Detail Struktural dan Persyaratan Mekanis Kandang harus mempertahankan bentuk geometrisnya selama penempatan, menahan gaya tekuk. Luas penampang tulangan ($A_s$) yang diperlukan harus memenuhi: $$ A_s \ge \rho_{min} \cdot A_c $$ Di mana: $\rho_{min}$ = Rasio tulangan minimum (biasanya 0,5% hingga 1,0%) $A_c$ = Luas penampang total bored pile 2.1. Pengekangan dan Tulangan Geser Tulangan spiral berfungsi untuk mengekang inti beton, secara signifikan meningkatkan daktilitas tiang. Jarak ($s$) antar spiral ditentukan oleh: $$ s \le \frac{f_{ys} \cdot A_{sp}}{0.3 \cdot D_c \cdot f'_c} $$ $f_{ys}$ = Kuat leleh baja spiral $A_{sp}$ = Luas batang baja spiral $D_c$ = Diameter inti 3. Rekomendasi Teknik Struktural Profesional Fabrikasi kandang tulangan yang presisi adalah wajib untuk umur panjang struktural.
