摘要
本文根据有限元法与有限位移理论,对一座密索型斜拉桥进行了线性与非线性的固有振动空间计算,并将计算结果作对比,以揭示几何非线性因素对自振特性的影响。
This paper deals with the linear and non-linear dynamic analysis of Tienjin-Yonghe cable-stayed bridge with multi-stay cable system. The computational results are worked out to reveal the geometrically-nonlinear effects on the characteristics of free vibration of such bridges.
