Tension Drop in Cable-Band Bolts on Suspension Bridges
Abstract The tension (axial force) in cable-band bolts on suspension bridges decreases with time. Conventionally bolt tension was measured periodically and bolts were retightened when the measured tension was lower than that specified. The authors undertook a survey of the bolt tension on several suspension bridges and analysed the data. The results indicated that the bolt tension decrease has a certain tendency and, in particular, tension drop decreases markedly after retightening. This paper describes the method of investigation which the authors used to determine the tension in cable-band bolts together with the analysis of the data. In addition, proposals are given on how to determine the optimum bolt tightening time and an appropriate bolt tension value to use as criteria.
