Análise estrutural e dimensionamento de galpão em concreto pré-moldado visando obtenção de memorial de cálculo

Abstract

The sheds precast concrete constructions are widely used in Brazil. However the bibliography for the design and sizing of this type of structure is very limited. Considering that many of the criteria adopted for designing the components of this enterprise are adapted by concepts related to the structures of multiple concrete pavements molded on the local. The objective of this research paper is to analyze the guidelines taken on the elaboration of skeleton structures of a concrete pavement, developing a memorial calculation that will facilitate future sizing of light sheds. The research was conducted by means of structural analysis and dimensioning of the elements, from a deployed project in the city of Caxias do Sul, Rio Grande do Sul, Brazil. In the survey of active efforts on the structure, the constituent elements had their behavior observed both alone and together. The loads calculation were obtained by analyzing the results of the most critical moments and forces acting on each element. Being one of the main factors for developing this work the analysis of the efforts, because lack of knowledge about the real behavior of the structure due to the behavior of links is the main influence in the dimensioning. This way the present research paper contributes to the technical literature about analysis and sizing of light sheds.
