Abstract
This paper presents the design and verification of reinforced concrete floor slabs using the finite element method (FEM). The study focuses on a multi–story residential building located in Ho Chi Minh City, Vietnam. Structural analysis was performed to determine internal forces, reinforcement requirements, and serviceability checks including cracking and deflection. The floor system was modeled as two–way slabs supported by beams and columns, subjected to dead load, live load, and wall loads according to TCVN 2737:2023. The results show that the slabs satisfy strength, crack, and deflection requirements. FEM analysis confirms that the adopted slab thickness and reinforcement layout ensure both safety and serviceability under design loads.
