宽幅系杆拱桥中横梁的设计研究

The Design and Study of Middle Beam in Wide Tied Arch Bridge

本文以工程实例为背景,详细分析研究宽幅系杆拱桥各中横梁在施工安装顺序、安装位置和横桥向风荷载等因素影响下的内力状态,并提出相应建议,以供参考。

This paper is on the background of engineering example and detailed analyses every middle beam＇s internal force state in the wide tied arch bridge,every of which is differently influenced by many factors such as construction and installation sequence,installation location,transverse wind load and so on,and also have been proposed some recommendations for reference.
