摘要
无背索斜拉桥结构主塔作为悬臂梁来抵挡斜拉索传递的梁面荷载,因此将塔身倾斜组成了梁塔结构的平衡体系。对其平衡受力特点进行直观的简化分析,考察影响平衡度选取的相关因素,并提出了由平衡特征所决定的一些结构基本特性。
The pylon of a cable-stayed bridge without backstays acts as a cantilever beam to resist loads from the girder transferred by stay cables, therefore, the pylon shaft is made incline to form a kind of equilibrium system of girder-pylon structure. In this paper, the equilibrium force characteristics of the structure are analyzed in a direct and simplified way to check the related factors that may influence the choice of the balance degrees, and some basic features of the structure determined by the equilibrium force characteristics are illustrated as well.
