Análise da variação de custo de materiais de um edifício de múltiplos pavimentos, considerando-se a variação do sistema estrutural

Abstract

The structural conception starts from the premise of establishing an arrangement of the various structural elements as adequately as possible, taking into account the desired aspects of aesthetics, safety and economy for the enterprise. In multi-storey buildings, different types of structural systems can be chosen, taking into consideration the building superstructure and infrastructure. Choosing the appropriate model, makes possible to do the global analysis of the building and its behavior in relation to the adopted elements and the requested efforts, generating the analysis of the structural system. Therefore, we considered four structural systems developed from a single architectural plan, these systems differed from each other by the type of slab adopted, namely: solid slabs, ribbed slabs, precast ribbed slabs trussed in one direction and into both directions. Structural systems were launched in AutoQi Eberick 2020 software, where it was analyzed by the overall behavior of the buildings under study, generating reports on fundamental parameters such as global stability and horizontal displacements. From a critical analysis, it is possible to make a comparative study between the studied systems, aiming at the ideal solution for the situation to which the structure is submitted. It is known that each project has its particularities, however, this work aims to direct the engineer to choose the most efficient and economical option on the structural systems studied, influenced by the current market conditions.
