The occurrence of “initial cracking” in bridges during proof load testing (PLT) is a relatively brief procedure, taking only a few hours. Its long-term effects may play a role in future understanding of the future behavior of the bridge. In this paper, we document a brief period of PLT via interrogation an FBG sensor (central wavelength of 1554.2nm...
