One of the main raw materials in the Civil construction sector in Brazil is reinforced concrete, and since the advent of this material in constructions, several techniques have been developed, making the construction and maintenance process of reinforced concrete buildings more advanced. Despite this, the emergence of pathologies in the constructions is becoming more and more frequent and, therefore, the necessity of interventions as well. Among the possible interventions to be carried out are the recovery, repair and structural reinforcement of the construction. In view of this issue, there are many techniques and materials in the market that enable the recovery or reinforcement of construction performance, from the most traditional to the most innovative. Among the innovators, the use of polymeric materials in the structure is emphasized, mainly, the application of the carbon fiber composite that presents itself as an effective technique with several advantages of use. However, the dimensioning of structural reinforcement with carbon fiber composites, especially for flexural reinforced concrete beams, is a complex, time-consuming and inaccurate process. Taking this into consideration, this study is based on the development of an electronic spreadsheet with a user-friendly interface, through researches in articles and books specialized in the application of this material and in the normative considerations about the dimensioning of reinforced concrete beams, that makes the process faster, safer and more accurate sizing. Through the presentation of case studies and the discussion of results comparing the results achieved by manual sizing and through the spreadsheet, it becomes evident the effectiveness and accuracy of the worksheet, as well as if it achieves the desired objectives. In such a way that, with the help of ... (Complete abstract click electronic access below)
