摘要：
An analytical method for determining natural frequencies and mode shapes of torsional vibration of suspension bridges is developed by using the linearized deflection theory. This method takes into account the effect of gravitational stiffness due to dead loads of the stiffening girders, and its effect on natural frequencies of torsional vibration is investigated. A numerical example using data of an actual long-span suspension bridge is presented, and the computed results are given in tabular form. (C) 1997 Academic Press Limited.
