分离式双箱钢加劲梁自锚式悬索桥横向刚度的分析研究

Analysis and Study of Transverse Rigidity of Separated Double-box Steel Stiffened Beam Self-anchored Suspension Bridge

杭州江东大桥为跨度260m的空间自锚式悬索桥。该桥主梁采用分离式双箱钢加劲梁形式。该文通过对杭州江东大桥的分析研究,得出了用于空间杆系模型进行静、动力计算的横向刚度取值,为同类型钢加劲梁桥的设计计算提供了借鉴。

Hangzhou Jiangdong Bridge is a spatial self-anchored suspension bridge with 260-m span.The main beam of the bridge uses the type of separated double-box steel stiffened beam.The article analyzes and studies Hangzhou Jiangdong Bridge,gives the transverse rigidity value for the spatial member model to carry out the static and dynamic calculations able to provide the reference for the design calculation of the same steel stiffened beam bridges.
