176 Structural Reliability And Formwork Optimization For Residential C 🏠 Kembali ke Index 176 Structural Reliability And Formwork Optimization For Residential C 176-Structural Reliability and Formwork Optimization for Residential Concrete Columns: A Practical Approach to Seismic Resilience Rahasia Kolom Rumah Kokoh Anti Retak: Panduan Profesional Teknik Bekisting untuk Hunian Aman, Rapi, dan Berstandar Internasional Author: Edi Supriyanto Email: edisupriyanto@gmail.com Website: https://neurostruct.id/ Abstract (English) The structural integrity of residential buildings is critically dependent on the precision of reinforced concrete column construction. This paper examines optimal formwork (bekisting) practices for residential projects, emphasizing structural reliability, geometric precision, and seismic resilience. As Bali is prone to seismic activity, column confinement and reinforcement detailing must strictly adhere to SNI 2847:2019 and international standards. We analyze the impact of formwork rigidity and material quality on the final structural cross-section. The study provides a technical framework for residential builders to enhance column performance, mitigate cracking, and ensure long-term serviceability through systematic quality control and proper formwork selection. Abstrak (Bahasa Indonesia) Integritas struktural bangunan rumah tinggal sangat bergantung pada presisi konstruksi kolom beton bertulang. Makalah ini mengkaji praktik bekisting yang optimal untuk proyek residensial, dengan penekanan pada reliabilitas struktural, presisi geometris, dan ketahanan seismik. Karena Bali rentan terhadap aktivitas seismik, pengekangan kolom dan detail penulangan harus mematuhi standar SNI 2847:2019 dan standar internasional secara ketat. Kami menganalisis dampak kekakuan bekisting dan kualitas material terhadap penampang struktural akhir. Studi ini menyediakan kerangka kerja teknis bagi pengembang residensial untuk meningkatkan kinerja kolom, memitigasi retak, dan memastikan kenyamanan jangka panjang melalui kontrol kualitas sistematis dan pemilihan bekisting yang tepat. 1. Introduction In residential construction, the column serves as the primary vertical load-bearing element. Inadequate formwork leads to bulging, concrete segregation, and reinforcement displacement—defects that directly compromise the seismic resilience of the building. This research bridges the gap between complex engineering standards and practical, small-scale residential execution. 2. Analytical Methodology and Structural Design The load-bearing capacity $P_n$ of a reinforced concrete column under axial loading is governed by the equilibrium of forces in the concrete and steel, considering the strength reduction factor $\phi$: $$\phi P_n = \phi \cdot \alpha \cdot [0.85 \cdot f'_c(A_g - A_{st}) + f_y \cdot A_{st}]$$ Where: $P_n$ = Nominal axial strength ($kN$) $A_g$ = Gross area of the column section ($mm^2$) $A_{st}$ = Area of longitudinal reinforcement ($mm^2$) $f'_c$ = Compressive strength of concrete ($MPa$) $f_y$ = Yield strength of steel reinforcement ($MPa$) $\alpha$ = Factor for eccentricity and confinement (typically 0.80 for tied columns) To ensure this capacity is realized, formwork must maintain the specified $A_g$ and ensure reinforcement cover is maintained throughout the pour. 3.
