Key Point Research on Design of Support Constraint System for Steel Truss Girder Bridge
钢桁架梁桥支座的约束体系不同于传统梁桥结构,其设计方案的选择影响桥梁下部结构尺寸和支座选型.结合工程实例分析了简支结构、连续结构、两榀桁架、三榀桁架等因素对钢桁架梁桥支座约束体系设计的影响,提出了提高支座设计水平承载力、释放三榀桁架中桁纵向滑移约束等设计应对措施,可为同类桥梁提供参考.
The constraint system of steel truss girder bridge support is different from that of traditional girder bridge structure,and the selection of its design scheme affects the size of the bridge substructure and the selection of supports.Combined with engineering examples,the influence of simply supported structure,continuous structure,two trusses,three trusses and other factors on the design of the support restraint system of steel truss girder bridges is analyzed,and the design countermeasures such as improving the horizontal bearing capacity of the support design and releasing the longitudinal slip restraint of the truss in the three trusses are proposed,which can provide reference for similar bridges.
