“…The effectiveness of TRC in improving the bearing capacity of concrete structures has been confirmed in several research works [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. However, research on the fatigue performance of TRC-strengthened RC beams is insufficient.…”

For the investigation of fatigue damage behavior of textile reinforced concrete (TRC)-strengthened RC beams, in this study, eight RC beams were fabricated, and five of them were strengthened with TRC and tested under fatigue loading until failure, using a four-point bending setup. Research parameters included reinforcement ratio, textile ratio, and strengthening methods (single-side and U-wrapped). The failure mode, fatigue life, fatigue deformation, and other properties of TRC-strengthened beams were analyzed. Experimental results revealed that there were two fatigue failure modes for TRC-strengthened RC beams. In the first mode, the textile was snapped, but the steel bars did not rupture. In the second mode, both the textile and steel bars broke. Fatigue failure modes depended on the textile ratio. The TRC-strengthened beam’s fatigue life was significantly higher than the non-strengthened RC beam. At the same textile ratio, the TRC-strengthened beam’s fatigue life using the single-side method was longer than that using the U-wrapped method. With the increase in fatigue loading time, the midspan deflection of the TRC-strengthened beam was developed in three stages, namely rapid development stage, stable development stage, and destabilized development stage. The residual deflection and strain damage accumulation of tensile steel bars of TRC-strengthened beams were significantly reduced with the increase in textile or reinforcement ratios; thus, the beam’s fatigue life was prolonged.

“…The effectiveness of the flexural strengthening of RC beams and slabs with TRM has been experimentally investigated in the last decade in numerous publications (Bruckner et al 2006;Papanicolaou and Triantafillou 2006;Triantafillou 2007;Jesse et al 2008;Bösche et al 2008;Papanicolaou et al 2009;D'Ambrisi and Focacci 2011;Ombres 2011Ombres , 2012Elsanadedy et al 2013;Babaeidarabad et al 2014;Loreto et al 2013;Verbruggen et al 2016;Aljazaeri and Myers 2017a;Ebead et al 2017;Escrig et al 2017;Koutas and Bournas 2017;Pino et al 2017a, b;Raoof et al 2017;Raoof and Bournas 2017d). Targeting them to assess their flexural capacity, beam or slab elements have been subjected to monotonic three-or four-point bending.…”

Strengthening of Concrete Structures with Textile Reinforced Mortars: State-of-the-Art Review

et al. 2019

View full text Add to dashboard Cite

Textile reinforced mortars (TRM), also known in the international literature as textile reinforced concrete (TRC) or fabric reinforced cementitious matrix (FRCM) materials, have been widely studied during the last two decades as they constitute a promising alternative to the fiber reinforced polymer (FRP) retrofitting solution for strengthening of reinforced concrete members. This paper presents a state-of-the-art review on the strengthening of concrete structures with TRM. First, the tensile and bond behavior of TRM is described. Next, an overview of studies on the use of TRM for flexural, shear, confinement, and seismic retrofitting of concrete or RC members is included, and the key parameters are investigated.

Reforço à flexão de viga de concreto armado com TRM (Koutas et al, 2019) A efetividade do reforço aplicado à flexão segundo a técnica TRM em vigas de concreto armado tem sido objeto de estudo (Brückner et al, 2006;D'Ambrisi e Focacci, 2011;Babaeidarabad et al, 2014;Verbruggen et al, 2014;Gopinath et al, 2015;Verbruggen et al, 2016;Gopinath et al, 2017;Escrig et al, 2017;Ebead et al, 2017;Aljazaeri e Myers, 2017;Sheng et al, 2018;Masood, 2019;Park et al, 2019;Adnan et al, 2019;Muresan e Zwicky, 2020; Nguyen e Ngo, 2020;Cai et al, 2021;Giese et al, 2021). Tais estudos tiveram como objetivo a avaliação da resistência à flexão das vigas de concreto armado reforçadas com grelhas de carbono, fibra de vidro, basalto, aramida ou poliparafenileno benzobisoxazol (PBO) e submetidas a ensaios de três ou quatro-pontos.…”
