Abstract:An extensive model test program had been carried out to investigate the issues of ice loading on bridge pier model. This paper investigated design principle of three kinds of FBG sensor modules, including FBG-based displacement sensor module, FBG-based strain sensor module and FBG-based force sensor module. A series of calibration tests of all FBG sensors had been made to detect the sensitivity of FBG sensor modules previously. There were 12 FBG-based sensors applied to monitor the failure progress and to predict the cracking inside the bridge pier model. The results of the ice loading tests proved that the FBG-based sensor had many advantages, characterized by its small size, high precision, easier installation, water resistance and cold resistance, demonstrating promising potentials in cracking and failure monitoring of bridge pier model. ? 2009 SPIE.
