钢－混结合梁有限元分析技术研究及应用
Study and Application of Finite Element Analysis Technology on Steel-Concrete Composite Girder
摘要
Abstract
The suspended cable-stayed composite girder with three towers on the West 2nd Ring Road in Hanzhong City features compli-cated structure and difficult design.In this paper, the ANSYS boundary coupling mode is applied to build one finite element analysis model of the composite girder which satisfies the actual conditions to study the action characteristics of the steel box girder of the compos-ite girder section under the flexible cable composite system in the large-span girder bridge projects.The parameterization design language of ANSYS is applied to compile the analysis documents and optimize the control documents as well.The key issues such as the potential local extreme stress and the local stability are analyzed.The optimum section shape of the composite girder is obtained through calcula-tion.Accordingly, the beneficial reference is provided to the design of the complicated structures.关键词
