Abstract
This study was conducted to determine the effectiveness of the design of reinforced concrete slabs of several civil engineering projects in Tra Cu district – Tra Vinh province. Utilizing the design documents of 6 projects, these slabs were redesigned based on TCVN 5574 – 2018. The design results were compared with those provided in the design documents. The results show that most of the design in the provided documents was either greater than or equal to the end design studied: the slab thickness is from 0% - 20%, the steel percentage of the slabs are from 0% - 63,3%, and the concrete quantity is from 0% - 20%. In conclusion, it is recommended for engineers to select an optimal slab design technique in order to reduce dead loads, to provide a reasonablesteel percentage and still being capable of carrying loads, which will result in an effective design for the project.
