斜支撑下宽横隔梁连续箱梁桥受力分析

Force Analysis on Continuous Box Girder Bridge with Wide Diaphragm Beam under Oblique Brace

提出宽横隔梁的设计思路,这种方法与斜横隔梁相比设计和施工都较为方便,受力较为明确。通过不同的模型建立方式分析了宽横隔梁桥的受力特点,给出了宽横隔梁桥设计应注意的几个问题,供桥梁设计参考。

The design thought for wide diaphragm beam is put forward.Compared with oblique diaphragm beam,the design and construction are more convenient and the force is clearer.Through the different establishing model ways,the force characteristics of wide diaphragm beam are analyzed.Then some problems attended in the wide diaphragm beam design are proposed to provide bridge design references.
