Estudo e aplicação dos critérios de projeto do TQS pórticos na elaboração do projeto estrutural de um edifício residencial em concreto armado

Abstract

With the advancement of information technology, structural projects have been increasingly carried out with the aid of computational tools. Such tools are of Paramount importance in the current market, since they have a significant role in optimizing time for the execution of a structural project, as well as in helping the behavior of the structural model to approach as real as possible. However, it is important to note that for the correct use of computer software, the professional must always be aware of the theoretical bases by which the program is governed, since it is the responsibility of the engineer to use the appropriate design criteria so that the structure is consistent with safety standards. Based on this, this work consists of the study of a multi-storey reinforced concrete building, using the TQS® program, where the knowledge about the design criteria provided by the program regarding the analysis of the spatial portal will be deepened. For this purpose, the entries of existing values in the program for the spatial frame criteria were studied, so that it was possible to understand the functioning of each criterion and apply the knowledge obtained in the analysis of the project under study. Therefore, the choice of analysis and application of two design criteria was made. Since the first criterion chosen refers to the flexibility of the connections, where it was possible to analyze the variations of moments and displacement in the building in a situation where there was the consideration of the flexibility and in the situation where there was no consideration of the flexibility of the connections. The second criterion chosen for application and analysis is the transfer of 2nd order efforts, where a variation of the limit values of the Gamma-Z coeficiente was carried out, in order to analyze whether there would be a difference in efforts for the two situations chosen.
