摘要
本文简述了斜拉桥失稳的几种情形和需要研究的问题,提出了按霍威茨判别式判断斜拉桥体系的稳定性及塔柱、主梁自由长度的计算原理与方法。本文例举了一座钢斜拉桥塔柱、主梁自由长度及其稳定性的计算。
In the paper,various buckling forms and some relevant problems that need to be researched for the cable-stayed bridge are described. The Waveci's Criteria to distinguish the total buckling of cable- stayed bridge and the theory and method of calculating the effec- tive length of tower and main girder are also proposed.Finally, the calculation of the effective length of the tower and main girder for a certain steel cable-stayed bridge is illustrated.
