Análisis Comparativo Del Diseño Estructural De Vigas De Concreto Reforzado Según la NSR-10 Y el ACI 318 En Colombia

Abstract

This study aims to perform a comparative analysis of the structural design of reinforced concrete beams using the Colombian code NSR-10 and the international standard ACI 318, in order to identify similarities, differences, and their implications within the context of structural engineering practice in Colombia. The main design criteria are examined, including load combinations, strength reduction factors, minimum and maximum reinforcement ratios, flexural and shear design, as well as detailing requirements.

The adopted methodology consists of designing a representative beam under predefined geometric and loading conditions, applying each code independently. Subsequently, the results are compared in terms of required steel area, reinforcement distribution, stress control, and compliance with limit states.

The findings reveal differences in design procedures and requirements, particularly regarding structural safety criteria, shear design approach, and seismic design provisions. In this regard, NSR-10 incorporates specific considerations derived from the Colombian seismic context, which directly influence the final design and detailing of structural elements.

It is concluded that, although both codes share a common conceptual basis based on strength design principles, the particular adaptations included in NSR-10 lead to relevant variations in beam design, highlighting the importance of its proper application in the national context.
