Written by adminDecember 9, 2019 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.
Written by adminNovember 4, 2019 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?
Written by adminSeptember 20, 2019 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
Written by adminSeptember 4, 2019 Introduction 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
Written by adminJuly 9, 2019 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
Written by adminMay 30, 2019 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
Written by adminJanuary 17, 2019 Concrete Imaging and Scanning are used to assess the location and extent of sub-surface defects. Different non-destructive test methods have been developed and used over the past few decades. The following article briefly describes some of these methods, and their application in the structure inspection and structural
Written by adminJanuary 11, 2019 In a bridge structure, abutment refers to the substructure unit which supports the end of the structure (bridge span) and retains the approach fill (see Ontario Structure Inspection Manual). Abutments are commonly made of mass concrete, reinforced concrete, or wood. Usually, abutments consist of a number of components: +
Written by adminSeptember 4, 2018 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
Written by adminMay 24, 2018 In this article, we will briefly review how to Estimate Strength of Concrete Using NDT Methods. Compressive strength of concrete is by far the most important property of concrete. It represents the mechanical properties of concrete; for example, the 28 days compressive strength of concrete cylinders is
