Diagnostic load testing is one type of load test methods that can be used either as a means for estimating the load carrying capacity of an in-service bridge or as an acceptance test before the… Read More »Bridge Diagnostic Load Testing
On-site Evaluation of Concrete Strength is a main challenge in the condition assessment of existing infrastructure, or the quality control of new construction. Owners, maintenance managers of such existing concrete structures normally prefer non-destructive and non-intrusive methods to avoid further damage to an already struggling structure. In construction projects, switching to non-destructive means less intervention, shorter down-times, and saving money. However, all parties agree that the strength of concrete is… Read More »5 Methods for On-Site Evaluation of Concrete Strength
With recent advancements in Sensor technology, Structural Health Monitoring (SHM) systems have been developed and implemented in various civil structures such as bridges, buildings, tunnels, power plants, and dams. Many advanced types of sensors, from wired to wireless sensors, have been developed to continuously monitor structural condition through real-time data collection. However, there are still a remarkable number of questions associated with the use of SHM sensors. For designing a… Read More »Sensors for Structural Health Monitoring
Structural Health Monitoring for Bridge Structures have the potential to collect significant amount of information about the damage state of various structural components at the global and element level.
This article presents a brief review on Non-Destructive Testing of Concrete Foundations.

This technical note briefly discusses non-destructive evaluation of cold joints in concrete structures. We will review how structural engineers and quality control laboratories can utilize NDT methods to assess the quality and integrity of concrete on or around the cold joint. What is Cold Joint in Concrete? Cold joints in concrete primarily happen when there is a significant delay between different concrete pours. For examples, if there is an interruption… Read More »Non-Destructive Evaluation of Cold Joints in Concrete
Harvesting wind energy has been of special interest over the past decade. There are approximately 300 wind farms across Canada. Wind turbine structures are very complex. While the inspection of the turbine and tower has been very well developed, the literature on evaluating the quality, integrity and reliability of their foundation is relatively limited. In this article, we will review how Non-Destructive Testing of Wind Turbine Foundation can help engineers in… Read More »Non-Destructive Testing of Wind Turbine Foundation
Bridges are among the most important infrastructure facilities. So far, the inspection and testing of bridge structures have largely been limited to visual inspection, chain dragging, extracting cores, and in some cases, half-cell corrosion potential mapping. Lots of interesting research have been done by researchers around the globe to bring more innovative NDT solutions to this sector. The following article focuses on the applications of most widely used non-destructive testing for… Read More »Non-Destructive Testing for Detailed Bridge Condition Survey
Rebound Hammer test provides a practical and cost-effective solution for estimating in-place concrete strength. Recent developments in rebound hammers, and improved guidelines for estimating concrete strength can help structural engineers and condition assessment professionals in accurately classify concrete strength, and make data-informed decisions on the location of cores in a cost-effective framework. This article takes a quick look at the history of the method and recent developments. Share on linkedin… Read More »Estimate Concrete Strength Using Rebound Hammer
Pile Integrity Test (PIT) is normally performed by striking the pile head with a light hand-held hammer and recording the response of the pile using a motion transducer (i.e. accelerometer) coupled
