Model Tests for Concrete Highway Bridges in Manitoba Full Y Reinforced by Cfrp Reinforcements

چکیده
Accepting the challenge of the future in the field of civil engineering smart structure applications, the province of Manitoba is undertaking the responsibility of constructing the first bridge in Canada totally prestressed and reinforced for shear by cru:bon fibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. This paper describes the experimental program conducted at the University of Manitoba, Canada, to examine the behaviour of 1:3.6 scaled model of the bridge girders. The paper also discusses the analytical model used to predict the behaviour. A comparison between the predicted and the measured behaviour in terms of load-deformation and strain distribution are presented.

Recent Innovation for Concrete Highway Bridges
A new generation of concrete highway bridges has recently been built in Canada using new design concepts and advanced materials for reinforcing and prestressing concrete . This paper describes briefly the design and construction of three bridges. The first smart concrete highway bridge (Centre Street, Beddington Bridge, Calgary, Alberta) is prestressed by carbon fiber reinforced plastic (CFRP) ...
متن کاملShear Strengthening Using Cfrp Sheets for a Prestressed Concrete Highway Bridge in Manitoba, Canada
The use of heavier trucks demanded upgrading of a twenty-seven year old bridge in Winnipeg, Manitoba, Canada. Analysis of the precast prestressed concrete girders using the current AASHTO Code indicates a deficiency in the shear capacity. Shear strengthening using Carbon Fibre Reinforced Polymer (CFRP) sheets provides a low-cost solution by increasing the speed of construction and reducing traf...
متن کاملBehavior of Coupling Beams Strengthened with Carbon Fiber Reinforced Polymer Sheets
In this research, using the results of 6 tests, the effect of Carbon Fiber Reinforced Polymer (CFRP) sheets on the behavior of reinforced concrete coupling beams of shear walls is studied. First, in the experimental part of the study, four coupling beams with different reinforcements were manufactured and tested. Then, after the failure of the specimens, two of them were rehabilitated and stren...
متن کاملRepair and Strengthening of Highway Bridges with FRP
Two different design problems are commonly encountered by highway bridge maintenance engineers: the upgrade of existing members to handle increased load demand, or the repair of bridge members which have experienced impact events due to overheight vehicles. This paper shows that through the use of carbon fiber reinforced (CFRP) materials highway bridge girders can be effectively strengthened or...
