The flexural strengthening techniques of reinforced concrete beams using Externally Bonded (EB) FRP sheets or Near Surface Mounted (NSM) FRP bars have been very well established. The technology transfer has taken place into engineering design practice for two decades now through the introduction of design guidelines. However, the lack of design software in the market as well as the limited academic education of present engineers has been an obstacle against the wide spread of this technology as a preferred alternative for repair and strengthening. Recently, a US-based group has responded to this need by developing professional interactive software to analyze and design structural elements strengthened with FRP. One of the very first products that came out of this effort was the development of a detailed analysis and design tool on strengthening of RC beams. This software complies with the provisions of ACI 440.2R-17 and is available interchangeably in SI and US customary unit systems. It is capable of analyzing rectangular, T and inverted L sections strengthened with externally bonded FRP or NSM bars. It allows for one compression layer and three tension layers of steel and provides strength and serviceability calculations. It has a graphics tool for to-scale drawing of sections, and it offers a detailed professional design report. The premium version is equipped with a graphics based optimized design feature that eliminates the need to perform design iterations. Its user-friendly interface is an asset to any design office.
