【摘要】 混合梁斜拉桥结合段为不同材料的结合,其传力机理和构造形式都相当复杂,是混合梁最关键的受力位置之一,其合理设计对确保大桥施工和运营阶段安全、耐久都有十分重要意义.以吴江市学院路跨京杭运河钢混斜拉桥为例进行结合段应力分析,通过运用大型通用有限元ANSYS等软件建立全桥混合模型,对吴江学院路大桥钢混结合段进行数值仿真计算,掌握其三维应力状态,验证钢混结合段设计的安全性与科学性,为设计和施工提供合理、可靠依据.更多还原

【Abstract】 Hybrid girder cable-stayed bridge segment is a combination of different materials,and its force transmission mechanism and structural forms are quite complicated.Its reasonable design is of great importance to ensure the safety and durability of the bridge construction and operation.In this paper,the stress of the Grand Canal steel-concrete cable-stayed sections across Wujiang College Road is analyzed as an example.Through the use of large-scale general-purpose finite element softwares such as ANSYS to establish the whole-bridge model for the simulation calculation of the steel-concrete joint sections of the Wujiang College Road Bridge,so to understand its three-dimensional stress status,verify the safety and scientificalness of the design for the steel-concrete joint sections and shed light upon the design and construction.更多还原
