For nearly three decades, the Vietnamese standard 2737:1995 has been fundamental in predicting the impact of loads on construction projects. Many projects and drafts have been developed to address the existing limitations of this set of standards. Issued by the Ministry of Construction, TCVN 2737:2023 has undergone significant revisions and additions, particularly concerning load impacts on construction structures. This study was conducted to deepen the understanding of the impact of wind load according to this standard. Four actual grade 2 reinforced concrete structures designed according to the old standard TCVN 2737:1995 were simulated to withstand the impact loads according to TCVN 2737:2023. The results showed that the standard static wind load has a higher average value of 0.935 times than TCVN 2737:2023, indicating that the wind load check problem under the new standard is more accessible to meet the related deformation requirements than the old standard. However, for the design according to the first limit state, the wind load according to TCVN 2737:2023 is more robust than 1.5 to 2..3 times due to different confidence factors. The research results will provide a scientific basis for proposing appropriate reinforcement and renovation solutions for each old structure. Trích dẫn: L. Hoang, L.T. Tu, L.T.A. Hong, D.H.
