钢管混凝土中承拱桥吊杆横梁受力性能分析

Load bearing capacity test of suspension member transversal girder of CFST half-through arch bridge

通过足尺寸吊杆横梁试件试验,验证了拱肋为钢管混凝土三角形桁架结构吊杆横梁的设计承载力,并对吊杆横梁的受力及变形进行了分析,提出了吊杆横梁施工的改进技术方案,保证了工程设计和施工质量。

By testing full size pieces of suspension member transversal girder, the design bearing capacity of the suspension member transversal girder in triangular concrete filled steel tubular truss arch rib is verified,its mechanical behaviour and deformation are analyzed,the construction technology plan is improved,and the design and construction quality are guaranteed.
