Abstract:

In this project, Florida International University researchers used segments from a demolished concrete segmental bridge with internal tendons to study damage to post-stressed tendons and to test the effectiveness of various methods of non-destructive testing (NDT) for detecting damaged tendons. ; Tendon damage was investigated by examination of segments removed from an interstate highway off-ramp, in laboratory tests of mockups, and in computer simulations. Six detection technologies were studied, some onsite and some in the laboratory: impulse response, infrared thermography, magnetic flux leakage, acoustic emission, interferometric phase radar, and inductance measurement. ; Improved methods of inspecting concrete structures for damage to tensioning cables can help to detect damage earlier, prevent more serious damage, and lead to a better understanding of the processes that damage tendons and better construction methods.
