The introduction of new technologies in civil construction is interconnected to advances in the area of information technology. The use of computer programs contributes to the way of planning, designing, dimensioning, executing and managing works. In the area of structural projects, one example is the software CAD / TQS, which has great applicability in national companies, assisting in the dimensioning, detailing and presentation of reinforced concrete projects. However, as complete as they are, there is no program that is at the stage of adequately equating all the variables present in a project, therefore, they are still dependent on the human factor. One of the reasons for this dependency is the critical interpretation of the results and validation with the regulatory standards. Therefore, it is of interest to identify the limitations of the program so that the professional, when using the program, can do it properly. It is believed that among the stages of the processing of a building, the detailing of the structural elements can present interesting results because it presents variations in the reinforcement configurations. Therefore, the objective of this article is to explore the structural design stage, which covers the details of reinforced concrete beams automatically generated by the CAD / TQS program, bringing comparisons with that specified in the Brazilian standard ABNT NBR 6118 (2014), which governs the dimensioning and detailing of reinforced and prestressed concrete structures. The methodology consists of launching the structural design in the CAD / TQS software, configuring the design and detailing criteria so that they are as close as possible to NBR 6118:2014, analyzing five different situations of the same beam, changing its characteristics to create new detailing cases. And, evaluating what the program provides with what is presented in the standard. In general, the program presented results that are consistent with that presented in the standard, there were situations that the standard was not so clear and the program adopted criteria similar to those of other authors, however it demonstrated its weakness in the choice of the most practical configuration for execution. Examples of this are the anchoring with hook on the end supports, the spacing of the transverse reinforcements and the decaling of the longitudinal reinforcement. |
