| Abstract: | The theory of string vibration is employed to analyse the simple harmonic vibration and the forced vibration of the cables in the cable-stayed bridege. The tensions at a normal atmospheric temperature are calculated by using the measurd results of the vibration frequences of the cables at normal temperatures. On the basis of the above calculations, the tensions of the cables at other temperatures are deduced by using the method of linear interpolation. A comparision is made between the calculated results and measured ones. |
