First Smart Bridge in Canada
On November 5, 1993, the City of Calgary completed the construction of the first smart prestressed concrete highway bridge built in Canada. A total of six pretensioned girders of a continuous two span skew highway bridge were prestressed using carbon fibre composite cables (CrCC) developed by Tokyo Rope, and Leadline rods produced by Mitsubishi Kasei, Japan. This paper describes the constructio...
متن کاملFirst Smart Highway Bridge in Canada
The Beddington Trail/Centre Street, Calgary, Alberta, Canada, is the first prestressed concrete highway bridge built in Canada pretensioned by Carbon Fiber Reinforced Plastic, FRP, tendons. It is also the first bridge which has utilized a structurally integrated optical sensors system to monitor the behaviour. The bridge is completed and was opened to traffic on November 5, 1993. The project in...
متن کاملLong Span Bridges
Population growth followed by the dramatic increase and demand for new services created an urgent and overwhelming need for infrastructures of civil engineering structures. However, the current infrastructure work using various techniques and conventional materials for construction will not solve the traditional and continuous deterioration of concrete structures due to corrosion of steel. One ...
متن کاملSmart Control of a Geothermally Heated Bridge Deck
This manuscript describes the “smart” control system designed for a geothermal bridge deck heating system. The control system integrates concepts of model predictive control with a first-principles bridge deck model and hourly computerized National Weather Service (NWS) forecasts to prevent bridge icing without the use of salt or other chemical de-icing materials. The proactive nature of the co...
متن کاملA methodology for Determining the Seismic Vulnerability of Old Concrete Highway Bridges by Using Fragility Curves
Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...
