Common Defects in Bridge Structures

The collapse of Ponte Morandi in Genoa, Italy (read more) and Florida International University pedestrian bridge (read more) have raised concerns about the safety and reliability of existing and new bridge structures. common Defects in bridge structures can affect the overall safety of the bridge structures. Different deterioration mechanisms can lead to major defects. Exiting infrastructure in Read more about Common Defects in Bridge Structures[…]

Acostic Emission Monitoring

Acoustic Emission Monitoring for Civil Infrastructure

Acoustic Emission is referred to the radiation of acoustic waves in solids as a result of damage or any irreversible change in its internal structure. Acoustic emission monitoring is well-known for its application in structural health monitoring of civil infrastructure. Structural Health Monitoring Health monitoring is a process of implementing inspection, evaluation, reaction, re-inspection and re-evaluation in Read more about Acoustic Emission Monitoring for Civil Infrastructure[…]

How to Evaluate Concrete Piles?

Structure inspection manuals such as the Ontario Structure Inspection Manual (OSIM) mostly emphasizes on the visual inspection and physical condition of bridge structures. The visual inspection methodology in this guideline consists of close up visual assessment of defects in the superstructure and substructure. This methodology is limited to inspection of elements that are at the arms Read more about How to Evaluate Concrete Piles?[…]

Damaged Bridges

How to Test Damaged Bridges?

Damaged Bridges are a major concern in the maintenance and operation of transportation infrastructure. Bridge structures in North America were mainly developed in the 1960’s and 1970’s and are rapidly approaching the end of their initial service life. Major mega cities in North America spend millions of dollars each year to keep these structures safe and Read more about How to Test Damaged Bridges?[…]

IOT - Intelligent Bridge Monitoring

Intelligent Bridge Monitoring

Have you ever imagined what would happen if highway bridges could speak?: “That I broke an arm? That I have a steel tendon ruptured? …” Well, they are not too far anymore. Last week, I had the chance to participate in a presentation by Jacques Cartier and Champlain Bridges Incorporated (JCCBI) in the GTA, and Read more about Intelligent Bridge Monitoring[…]

The Bridges of The Future

The Canadian Highway Bridge Design Code (S6-14, 2014) considers a service life of 75 years for newly constructed bridge. What does this mean in engineering terms? It means that the bridges of the future should have satisfactory performance, both durability and structural, during the proposed life-cycle. This can be quite challenging when we look closely; Read more about The Bridges of The Future[…]
