Canadian Bridge Design Code Provisions for Fiber-Reinforced Structures

Mechanical properties of epoxy nanocomposites using titanium dioxide as reinforcement – A review

“…FRPCs were being considered as a substitute for the conventional steel materials in reinforced concrete structures and guidelines for the selection of polymer adhesives for concrete have been highlighted by ACI Committee-503 [2] and Uomoto et al [3]. Issues related to selection and applications for FRPC have been discussed by Karbhari [4], Einde [5] Bank [6], Bakht [7], ACI Committee 440 [8] and Nanni et al [9]. In FRPC, the adhesion quality between fibers and the matrix plays a major role in the overall performance.…”

Análise teórica e experimental de vigas de concreto armadas com barras não metálicas de GFRP

“…No caso de ruína por ruptura da barra de FRP, esta se apresenta de modo repentino e brusco, pois não existe escoamento das barras de FRP, sendo que elas possuem comportamento elástico linear e ruptura frágil. A ruína por esmagamento do concreto é mais recomendável, pois existe uma certa ductilidade neste tipo de ruína em conseqüência do desenvolvimento do comportamento plástico do concreto antes da ruína (ACI 440.1R-03, FIB 9.3 TG-2003, Bakht et al 2000, Nanni 2005).…”

Serviceability Analysis of Rc Beams Reinforced With GFRP Bars- A Review

“…An overall performance factor (J factor), calculated as the ratio of the product of moment and curvature at ultimate to moment and curvature at a concrete strain of 0.001 (corresponding to the concrete proportional limit) is used in the Canadian Highway Bridge Design Code. The Canadian code suggests minimum acceptable values for the performance index, which is four for rectangular sections and six for T sections (Bakht et al 2000) 20 . Another method considers the magnitude of the net tensile strain in the outer layer of FRP bars because the concrete compressive strain reaches the ultimate limit state.…”
