| Abstract: |
Received a BEng (Hons) degree from Kingston University, and has been involved in numerous conventional and acoustic instrumentation projects. Received his BSc from Durham University, is a CEng, and Member of the Institute of Civil Engineers (MICE-UK). Acoustic monitoring of cable supported structured has developed into a useful and reliable tool for engineers. The information provided by proper monitoring gives owners and structural advisors confidence in tracking any deterioration that is occurring in the post-tensioning system on presetressed concrete bridges. When visual inspections reveal problems in some of the strands supporting the structure, a structure-wide deployment of an acoustic monitoring system can buy the owner time to secure funds, design, plan, procure, and build a replacement structure. In the meantime, the tracking of active deterioration allows the owner to make decisions regarding safe loads, or load restrictions and to gain maximum utility from the bridge. |
