Abstract

This paper presents the finite element analysis of bending moments in reinforced concrete beams of a multi-story building using ETABS software. The methodology includes global structural modeling, load assignment and internal force extraction based on finite element analysis. The bending moment envelopes were obtained for critical beams in the structural frame, serving as the basis for reinforcement design. Results demonstrate that the computed bending moments are within the acceptable range for structural safety and serviceability according to TCVN 5574:2018..

Keywords:Finite element method; Bending moment; Reinforced concrete beam; Structural analysis; TCVN 5574:2018
