Dimensionamento de lajes planas protendidas: estudo de caso biblioteca campus Alegrete – UNIPAMPA

Abstract

With the evolution of civil construction, methods that accelerate construction processes and structural models that allow more complex and larger span architectures are increasingly needed. In this context, prestressing is becoming prominent and prestressed flat slabs are useful for large planes with reduced amounts of columns, beams and structures with smaller thicknesses. This work aims to dimension the slab of the libraries of the Federal University of Pampa (UNIPAMPA), with the TQS software. The typology used was a flat slab protected with non-adherent prestressing of greased strands. After sizing, the passive and active reinforcement were detailed, comparing the results obtained with the work performed by Brazeiro (2013) using the Equivalent Gantry method of NBR 6118 (2013) in the same structural element. The use of software in structural sizing facilitates the process of structural optimization, generating more economical designs by the ease of changing parameters and almost immediate results when compared to manual processes.
