Abstract

Abstract

To master stress variations in the prestressed tendons of retard-bonded prestressed concrete beams in the Desheng Sports Center of Foshan, Guangdong, retard-bonded prestressed intelligent tendons made of intelligent steel strands with Fiber Bragg Gratings wrapped with steel strands were applied into the engineering monitoring. The results indicated the retard-bonded prestressed intelligent tendons could ensure convenience of construction and measure stress of tendons at any time, accurately grasp actual prestress loss degrees in prestress tensioning construction. It was of high monitoring accuracy and could accurately reflect the changes in stress of the tendons in the structure with the construction processes, the external environment, and the solidification of adhesives. It provided reliable data support for the design and construction quality of retard-bonded prestressed concrete projects.
