斜横梁索梁锚固的斜拉桥主梁剪力滞分析

Analysis of Shear Lag Effect on Box Girder of Cable-Stayed Bridge with Anchored Cable by Inclined Diaphragm Plate

采用通用有限元ANSYS软件,研究某单塔单索面、斜横梁索梁锚固的斜拉桥主梁剪力滞效应,分别计算了箱梁顶板和底板的剪力滞系数,分析了斜拉索索力对主梁剪力滞的影响,计算结果可为同类型桥梁设计提供参考.

The shear lag effect on box girder in P.C. cable-stayed bridge with single cable plane and single tower is studied by using Ansys software. The shear lag coefficients of the box girder＇s upper plate and bottom plate are computed, and the effect of cable force on shear lag is studied. Results in this paper can be of reference to the bridge design of the same type.
