Flexural performance of concrete beams reinforced with epoxy resin/glass and carbon fibers composites
(2021-01-01)
Factors such as project and execution errors, lack of maintenance and inspection, and increases in loading can cause deficiencies to reinforced concrete structures. In this regard, there is the necessity of the application ...
Dimensionamento automático de vigas e lajes de concreto armado
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2016-11-16)
This work deals with the development of a computational code that realizes the dimensioning of structures of automatically reinforced concrete, be it of beams, rectangular section and section T, submitted to the efforts ...
Estudo da deflexão em vigas de concreto armado com barras não metalicas
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia CivilUTFPR, 2021-11-26)
This work is based on the replacement of conventional steel bars by FRP (Fiber Reinforced Polymer) bars in reinforced concrete beams. A steel reinforced concrete beam was fabricated following the recommendations of ABNT ...
Estudo da contribuição do concreto à tração no aumento da rigidez de vigas em concreto armado: efeito de tension-stiffening
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia CivilUTFPR, 2019-12-05)
In the case of reinforced concrete elements, in the post-cracking section, the intact concrete between the cracks continues to carrie tensile stresses due to the transfer of bond forces between reinforcing bars and the ...
Experimental study of reinforced masonry beams
(IBRACON - Instituto Brasileiro do Concreto, 2019-11-11)
An experimental program on reinforced concrete masonry beams was conducted aiming to better understand the behavior of reinforced masonry beams. The beams were designed to fail in flexure, assessing cracking patterns, ...
Programa para automatização do dimensionamento de vigas em concreto armado à flexão
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2018)
In the present work, a computational code has been developed for the dimensioning of reinforced concrete beams. The beams in consideration on this work are the beams with rectangular straight section or beams with straight ...
Influence of reinforcement's corrosion into hyperstatic reinforced concrete beams: a probabilistic failure scenarios analysis
(IBRACON - Instituto Brasileiro do Concreto, 2015-08-01)
AbstractThis work aims to study the mechanical effects of reinforcement's corrosion in hyperstatic reinforced concrete beams. The focus is the probabilistic determination of individual failure scenarios change as well as ...
Failure behavior modeling of slender reinforced concrete columns subjected to eccentric load
(2015)
