Non Destructive Detection of Fractures in Prestressed and Post-Tensioned Cables

The PT Cable Break Detection (CBD) System is an effective non-destructive method for locating fractures in prestressed cables and both ungrouted and grouted post-tensioned cables and bars. There are two systems available for detecting fractures on different types of structures, the Line Scan Method and the Rotating Scan Method. The Line Scan Method is used to evaluate one cable at a time while the Rotating Scan Method is used to evaluate several cables at one time. These systems proved effective in location fractures on a project on the Champlain Bridge in Montreal, Canada.
