NONDESTRUCTIVE DETECTION OF REINFORCING MEMBER DEGRADATION

摘要

A nondestructive method of and apparatus for detecting degradation of reinforcing members embedded within a structure is disclosed. Degradation can arise from many sources, such as corrosion, fracture, cracking, fatigue, chemical reaction, etc. The device includes an inducing instrument to induce a vibration of the reinforcing members and a measuring device to detect the vibration of the reinforcing members. The measurement is analyzed to detect the presence of reinforcing member degradation or reinforcing member-to-concrete bonding. The device may include a controller to enhance the detection. The device may also include an amplifier to further increase the energy in the waves imparted to the structure and the acoustic waves detected by the measuring instrument.
