Modeling of insulated CFRP-strengthened reinforced concrete T-beam exposed to fire

Thermal analysis of GFRP-reinforced continuous concrete decks subjected to top fire

“…In addition, the authors (Hawileh and Naser 2012) predicted with a high level of accuracy the mid-span deflection response results for the entire fire exposure. It should be also noted that the authors developed in a previous study (Hawileh et al 2009) a FE model that simulated the thermal and mechanical response of reinforced concrete beams externally strengthened with CFRP laminates subjected to fire loading. The predicted and recorded temperatures at different depths of the beam's cross-section were in close agreement (Hawileh et al 2009).…”

“…It should be also noted that the authors developed in a previous study (Hawileh et al 2009) a FE model that simulated the thermal and mechanical response of reinforced concrete beams externally strengthened with CFRP laminates subjected to fire loading. The predicted and recorded temperatures at different depths of the beam's cross-section were in close agreement (Hawileh et al 2009). Thus, the developed FE model in this study can predict with a good level of accuracy the temperature distribution in the RC slab during the entire fire exposure.…”

“…The problem of studying fire resiliency in reinforced concrete (RC) beams strengthened with CFRP composites and subjected to bottom and top fire has been addressed numerically by the authors and co-workers (Hawileh et al 2009(Hawileh et al , 2011Naser et al 2014Naser et al , 2015. These numerical studies were benchmarked against several experimental investigations related to the same subject (Blontrock et al 1999;Williams et al 2006;Tan and Zhou 2011).…”

Advances of Finite Element Analysis for FRP Concrete Beams

“…Although significant research has been conducted to investigate various aspects of the behavior of FRP RC beams, few studies on the performance of FRP concrete beams subjected to fire exposure have been reported. Among the few are the study of response of a reinforced RC beam in the entire range of loading up to collapse under fire (Kodur & Dwaikat 2008a,b), the nonlinear 3-D finite element model presented by Rafi et al (2008) for the prediction of response and crack formation and propagation of steel and FPR reinforced concrete beams under a combined thermal and mechanical loading up to failure, the prediction of the fire behavior of FRPstrengthened RC beams by Gao et al (2009), and the modeling of insulated CFRP-strengthened reinforced concrete T-beam exposed to fire (Hawileh et al 2009). …”

Heat Transfer Analysis of Reinforced Concrete Beams Reinforced with GFRP Bars

“…In addition, the RC beams showed that they can pass the building regulations for fire safety by withstanding the fire test more than 90 min. Hawileh et al (Hawileh et al, 2009 developed FE models that predicted the performance of RC beams strengthened with insulated carbon CFRP plates subjected to bottom and top fire loading. The models predicted with reasonable accuracy the experimental results of Williams et al (Williams et al, 2008).…”
