Sistematização do cálculo e verificação de sistemas estruturais de galpões pré-fabricados de concreto

Abstract

This research is the systematization of the calculation and verification of a type of a very typical structural system of precast concrete in Brazil: the sheds. Through this research it is showed the main structural systems for this type of construction currently in use in Brazil. It also describes the component elements of these systems detailing the design techniques. Following it is a detailed the considerations of the actions over them and how to calculate the strain and displacement. With all previous data collected it is shown how the design is made with reinforcement of the roof s beam and how to guarantee that it meets with the relevant Brazilian standards. In the sequence, examples are made so that the reader can consolidate all the concepts involved in the previous sections. It shows the calculation and verification and finally points out the possibilities of improvement in some systems, detailing it. Finally, it highlights the points can still be studied to improve the design and the knowledge of sheds precast concrete.
