异型钢人行天桥空间静动力分析

Space Static and Dynamic Analysis on Deformed Steel Pedestrian Overpass

以某商业区人行天桥为依托工程,针对城市异型景观人行桥的受力特点,阐述了此类桥梁的设计及构造要求;借助于有限元软件,对此桥施工及运营阶段的受力特性进行了分析,指出了此桥设计中的关键部位,并给出了细部构造加强的措施,以确保桥梁结构安全可靠。初步给出了异型桥梁的空间分析方法及设计原则,为以后类似工程设计提供参考。

Based on certain commercial zone pedestrian overpass,focused on the loading features of urban deformed steel landscape bridge pedestrian overpass,the design and structure requirements of this type of bridge has been set forth. With the help of finite element software,bridge loading features during construction and operation period have been analyzed and the key section of the bridge design has been pointed out and detail structure and reinforcement measures have been proposed to ensure the safety and reliability of the bridge structure.The preliminary space analysis methods and design principles of the deformed steel bridge have been given providing reference for similar engineering.
