Given the need for flexural strengthening in reinforced concrete beams, a study has developed that supports appropriate methods. This paper presents a systematic review of the numerical modeling and structural performance of reinforced concrete beams flexurally strengthened with carbon fiber-reinforced polymers (CFRP) using the Near Surface Mounted (NSM) technique. The objective is to identify advances, limitations, and trends related to strengthening. A survey of the most relevant studies for this research was conducted using the Parsifal platform. Searches were conducted in CAPES, Google Scholar, ScienceDirect, and Scopus databases. After screening, 117 articles were qualified and analyzed using tools such as VOSviewer. The results showed a predominance of numerical studies using the Finite Element Method (FEM), with good agreement between computational analyses and experimental tests. It is concluded that the gains in flexural strength in beams strengthened by NSM compared to traditional methods, thus, showed that the NSM technique is efficient, fast and durable.
