Graphical 3D Visualization of Highway Bridge Ratings

Aging highway infrastructure requires effective rating methodologies to prioritize bridges for rehabilitation and repair. To aid engineers in decision making regarding bridge maintenance, a three-dimensional 3D visualization system is developed for rating reinforced concrete deck-girder bridge. Color codings show the most probable mode of failure for girder cross sections under combined moment-...

Evaluation of Highway Bridge Strength Considering Parapets

This paper describes a study evaluating increase in design strength, performance and capacity when including bridge parapets in a bridge analytical model. Traditionally, concrete parapets are treated solely as superimposed dead load in an overall bridge structural design. Parapets are detailed from a safety standpoint to resist impact forces from vehicle loading. However, in the global design m...

First 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...

Analysis of Structural Vibrations due to Passage of Underground Trains

During the last decades, the railway traffic in densely populated areas has increased. At the same time, passenger trains have become faster and freight trains have become heavier. Consequently, trains are an increasing source of ground vibration, which may be a nuisance to people, buildings and sensitive equipment. In this research, a two-dimensional dynamic system, including underground train...
