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 developed countries are nearing the end of their initial service life design. According to the… Read More »Common Defects in Bridge Structures

Nondestructive testing of concrete tanks (1)

Non-Destructive Testing of Concrete Tanks

Inspection and Non-destructive Testing of Concrete Tanks at regular intervals will ensure the safety and reliability of these assets. Application of NDT methods for inspection and monitoring will help detect and quantify potential defects and deterioration mechanisms at early stage. Test results will help the owners in prioritizing repair and maintenance needs, and prevent excessive damages which can have great financial and environmental impacts. In this article, we will briefly review… Read More »Non-Destructive Testing of Concrete Tanks

NDT Methods for Evaluation of Parking Garages

  • by

Non-destrcutive Testing- NDT Methods for Evaluation of Parking Garages can help improve the quality of routine inspection and maintenance. Parking garages require routine inspection and maintenance to ensure they remain safe and operational. Weather it is a public parking in extremely busy downtown areas, or a private condominium structure, proper maintenance is needed to keep them safe. The importance of parking garages is often ignored, simply because nobody lives in… Read More »NDT Methods for Evaluation of Parking Garages

Condition Survey for Bridge Decks

4 Methods of Condition Survey for Bridge Decks

Exposed Concrete Decks suffer from various deterioration mechanisms; i.e. freezing and thawing, corrosion. The most significant consequence is the delamination of concrete, which could eventually trigger other damage mechanism, such as corrosion. The maintenance of deck slabs is quite challenging mainly because it normally involves large areas; In many cases, closing the deck to traffic is extremely difficult, if not impossible. Existing (traditional) methods of condition survey for bridge decks… Read More »4 Methods of Condition Survey for Bridge Decks

NDE of Concrete Dams

4 Methods for Nondestructive Evaluation of Concrete Dams

Appropriate operation and maintenance of concrete dam structures are essential to ensure the safety of the structure, and reducing risk. Concrete surfaces should be examined in a regular basis to identify spalling and deterioration due to weathering, or extreme stresses, or other physical, or chemical damage mechanism. Nondestructive Evaluation of Concrete Dams can provide useful information about the condition and quality of concrete materials, extent of damages, and mechanical properties of concrete. What… Read More »4 Methods for Nondestructive Evaluation of Concrete Dams

ASR-Corrosion

Corrosion in Concrete

It is common to see map crack networks over the concrete elements of aged infrastructure along with leaching signs. It might be interesting to know that no structural collapse has been reported so far because of the ASR cracking in North America. However, the question arises as to whether it is required to manage ASR cracking within concrete structures. In this article, we will study the combined effect of corrosion… Read More »Corrosion in Concrete
