Fatigue safety level provided by Brazilian design standards for a prestressed girder highway bridge

Optimization of Precast Prestressed Concrete Bridge Girder Systems

60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...

Strengthening of Impacted Prestressed Concrete Bridge I-Girder Using Prestressed Near Surface Mounted C-FRP Bars

First Smart Prestressed Concrete Highway Bridge in Canada

Deterioration of concrete members due to corrosion of steel reinforcements is one of the major problems which reduces the service life time of bridges, especially in Canada due to the use of de·icier applications. The cost of correcting corrosion-induced distress in bridges is high compared to the capital cost of the structure. To overcome this problem, the City of Calgary has decided to constr...

Shear 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...
