Abstract:In order to monitor the bridge cable tension,a new imelligent GFRP-OFBG
   sensor is introduced.The temperature and strain sensing properties of
   GFRP-OFBG sensor are studied through the calibration experiment.The
   limit strain of GFRP-OFBG sensrs with different diameters is compared.It
   is verified that the GFRP-OFBG sensors with diameter of 7 mm are
   suitable for the application of the bridge cables tension monitoring,and
   its limit strain is about 8000.Finally,the installation of GFRP-OF-BG
   sensors have been explored in the arch bridge tie cables.The tie cable
   tensile process is successfully monitored utilizing GFRP-OFBG
   intelligent sensors in Sichuan E Bian Dadu river. Based on the
   monitoring data for a year,the tie cable tensile result and the
   operating conditions have been verified.
