双跨连续钢箱梁人行天桥设计

Design of double-span continuous steel box girder pedestrian bridge

为进一步探究双跨连续钢箱梁人行天桥主要结构受力特征,通过Midas Civil 2021有限元软件对主桥的应力、挠度及自振频率进行计算分析。结果表明:该主桥结构设计满足规范要求,且具有一定的安全储备,安全可靠。可见此设计成果对同类型人行天桥的设计具有一定的参考价值。

In order to further explore the main structural characteristics of double-span continuous steel box girder pedestrian bridge,the stress,deflection and natural vibration frequency of the main bridge was calculated and analyzed by Midas Civil 2021 finite element software.The results show that the main bridge structure design can satisfy the standard request and have a certain safety reserve,which is safe and reliable.It is concluded that the design results of this paper can be a certain value of reference for engineering application while designing the same type of pedestrian bridge.
