Projeto de vigas pré-moldadas e protendidas tipo T invertido para utilização em edifícios

Abstract

This work deals with the design and dimensioning of inverted T beams for use in residential or comercial buildings. The objective of this work is to analyze the different loading situations to which the beam is subjected since its production in the pretension lane until its final use in the building, use the design criteria foreseen in the brazilian norm and develop the calculation and detailing process of these beams. The entire implementation is carried out in a Microsoft Excel’s spreadsheet, and finally, graphs are made that try to evaluate the relationship between spans and maximum loads and compare these results for commercial and residential buildings, based on criteria defined in this work. The results are consistent with what is expected and present an acceptable way to automate the process of detailing this type of beams.
