Avaliação da fluência utilizando o método do ajuste do diagrama tensão-deformação do concreto e o método geral de dimensionamento de pilares de concreto armado submetidos à flexão composta oblíqua.

Abstract

This study aims to analyze the effects of creep on the design of reinforced concrete columns subjected to normal and oblique combined bending using the General Method. To this end, the programs FCNGEFLU and FCOGEFLU, developed by Professor Francisco José Pereira de Almeida, were employed for the design and verification of cross-sections of columns under these conditions. The results obtained from both software programs were compared with the master's thesis titled “Consideration of Creep in the Calculation of Second-Order Effects in Reinforced Concrete Columns” (CASAGRANDE, 2016), as well as with the PCalc software. Three column models extracted from the aforementioned thesis were analyzed, serving as a reference for comparing the results. The results showed that both programs provided slightly higher moments than those obtained by Casagrande and PCalc.
