The estimating method of tension imposed on bridge cables by measuring their natural frequency, so-called vibration method, is very convenient on the construction site of structures with cables. However, there still exist several problems concerning the flexural rigidity of cables that have to be overcomed so as to get reliable and accurate estimation as follows:
(1) The flexural rigidity of the cable is needed to be obtained beforehand, but few data have been reported in regard to the property.
(2) The accuracy of estimated cable tension, affected by the flexural rigidity in particular, is necessary has to be analysed theoretically.
(3) A simple method of estimating the flexural rigidity of cables on the construction site is desired.
In this paper, the above mentioned problems are theoretically and experimentally studied.
