Anyone who has observed a significant number of piles has seen that, inevitably, the pile is not perfectly straight after driving. In spite of the best efforts of contractors, there are a whole host of reasons for piles to end up out-of-plumb or to have a curve, sometimes referred to as pile sweep. For two, recent projects with numerous swept pile, the available research was determined to be limited in application given the investigated pile sizes, lengths and measured sweep. As a result, the project team chose to perform static load testing to evaluate the ultimate resistance of the swept...

Concrete is widely regarded as the most used man-made material in the world. Even with superb advances in modern concrete technologies to make more durable, longer-lasting structures today, the need for assessment and evaluation of existing concrete structures has never been higher. Non-destructive testing (NDT) of concrete is a commonly used (and often misused) approach to evaluate existing concrete structures. Learn more about non-destructive testing and how it can be an asset in the evaluation of concrete structures. This presentation will help you to understand: The difference between concrete NDT and other common NDE methods NDT for concrete strength versus...

In the nondestructive testing (NDT) field, industrial radiography is, arguably, one of the most expensive methods to perform. With regard to safety, however, it stands alone due to the risk of exposure to ionizing radiation. Many NDT methods share an inherent safety risk due to environmental hazards, but radiography is the only major method with high-dose radiation concerns. Due to the introduction of digital radiography techniques, those concerns are growing smaller with every innovation. Modern equipment reduces the required overall radiation exposure to fractions of the original dose. This reduction in total dose allows the operation to take place in...
