APPLICATION ON MEASUREMENT OF PRE-STRESS LOSS IN CONCRETE STRUCTURE WITH FIBER-OPTIC SENSORS

Tang Hongwei, Li Wansheng, Li Yuhong
  • Abstract:
    As one of the important works in the pre-stressed concrete structure design, magnitude of the pre-stress loss has not been measured conveniently until now. A suitable measuring technique for pre-stress loss is the studying goal of researcher in a long time. In the present work, the fiber-optic measuring technique has been introduced to measure the pre-stress loss, and all of the measuring works were conducted on the model of a wastewater tank. Result of the measurement shows that optical fiber sensor can be used to measure the pre-stress loss in engineering, and the short-term pre-stress loss of steel strand is strongly effected by the arranging manner of steel strand, the magnitude of pre-stress loss measured in the present work is less than 20%.
