Analysis of Concrete Structure Calculation Methods Based on SNI 2847-2002 and SNI 2847-2023 Using ETABS 21.2.0

Abstract

Purpose: This study aims to analyze the impact of the regulatory change from SNI 2847-2002 to SNI 2847-2013 on structural concrete, particularly in terms of calculation methods and structural modeling. The update in standards was introduced to enhance concrete quality and align with scientific advancements in structural engineering.

Methods/Design: The research compares manual calculations based on SNI 2847-2002 with analysis conducted using Microsoft Excel in accordance with SNI 2847-2013. The focus is on the dimensions of reinforced concrete beams and the required Ace value (area of tensile reinforcement), which significantly influences structural performance.

Findings: A significant difference in the Ace values was observed between the two standards. This discrepancy arises due to variations in the effective depth (d) and the sliding moment formula applied in each version of the standard. These differences directly affect various structural aspects, including flexural strength, stiffness, crack control, and beam deflection.

Practical implication: The transition from SNI 2847-2002 to SNI 2847-2013 has implications not only for technical calculations but also for structural design and safety. Structural engineers must understand and adapt to these changes to ensure their designs comply with updated standards and meet enhanced safety requirements.
