FIXED SECTION STRUCTURE OF TENDON AND STRESS MEASURING METHOD FOR TENDON

摘要

PROBLEM TO BE SOLVED: To provide a fixed section structure of a tendon and a stress measuring method for the tendon capable of making a measurement with a sufficiently high accuracy only by stress measurement of a magnetostriction method and easily measuring the change of stress with time in the stress measurement of the tendon. SOLUTION: In a tendon 1 anchoring part structure having the tendon 1, an anchoring member 4 anchored to the front end section of the tendon 1 and giving tension to the tendon 1 by fastening and an anchor plate 3 holding placed on a position opposite closer to the front end section of the tendon 1 than the anchoring member 4, a ring-like measurement object member 5 is interposed between the anchor plate 3 and the anchoring member 4, the outer side surface of the object member 5 is measured as a measuring surface 5A by the magnetostriction method and is measured as a measuring surface 5B by a strain gage method, and the strain gage is stuck on the measuring surface 5B by the strain gage method.
