Investigation of Glass Fibre Reinforced Polymer Reinforcing Bars as Internal Reinforcement for Concrete Structures

Johnson, David Tse Chuen 12 February 2010 (has links)
A study of the existing data shows that two areas of GFRP bar research among others are in need of investigation, the first being behaviour of GFRP bars at cold temperatures and the second being the behaviour of large diameter GFRP rods. Based on the results of experimental work performed, cold temperatures were found to have minimal effect on the mechanical properties of the GFRP bars tested. In addition, through beam testing, large 32mm diameter GFRP bars were found to not fail prematurely due to interlaminar shear failure. By evaluating the mechanical and durability properties of GFRP bars and behaviour of GFRP RC, it can be concluded that GFRP appears to be an adequate alternative reinforcement for concrete structures. Because of high strength, low stiffness and elastic behaviour of GFRP bars, issues of significant importance for reinforced concrete are bond development, influence of shear on member behaviour and member deformability.

THE EFFECTS OF FIRE ON INSULATED REINFORCED CONCRETE MEMBERS STRENGTHENED WITH FIBRE REINFORCED POLYMERS

Hollingshead, Kevin 02 June 2012 (has links)
Given the current global crisis of deteriorating infrastructure, structural rehabilitation has been the focus of much recent research in the field of civil engineering. Consequently, Fibre Reinforced Polymers (FRP’s) are becoming an increasingly common method for retrofitting deficient structures. However, skepticism regarding the structural performance of FRP’s during fire is preventing their widespread implementation in building applications. Because of the degradation of FRP material properties during heating, most current design codes completely neglect their structural contributions in fire design. The intention of this research thesis is to investigate the thermal and mechanical behaviour of insulated FRP retrofitted reinforced concrete structures at elevated temperatures. Two intermediate-scale reinforced concrete slabs were first strengthened with FRP and protected with spray-on insulation. Thermal results from fire testing of the slabs provided a basis on which to develop insulation schemes for larger specimens. These larger specimens consisted of two full-scale T-Beams and two full-scale columns, which were also strengthened with FRP and insulated. All of these specimens succeeded in obtaining four hour fire ratings upon fire testing. Though the FRP strengthening systems were compromised quickly during heating, the insulation provided sufficient protection to the T-beams and columns for them to resist the applied service loads throughout the duration of fire exposure. Detailed calculations were also conducted using thermal data from the full-scale specimen fire tests in order to predict the change in capacity of these structures with time. This thesis shows that, with careful considerations towards insulation and anchorage design, FRP-strengthened reinforced concrete structures are able to obtain fire ratings in excess of four hours. / Thesis (Master, Civil Engineering) -- Queen's University, 2012-05-29 15:46:00.801
