摘要
基于某大型钢结构人行天桥的设计,分析天桥结构设计的特点,围绕天桥结构的动力特性——自振频率的计算,展开详细、深入的分析,并得出一些结论和建议,可供类似工程参考借鉴。
Based on design of a large steel structure pedestrian overcrossing,the design characteristics of pedestrian overcrossings are analyzed in this paper.A detailed analysis is made on the calculation of pedestrian overcrossing dynamic properties：natural vibration frequency, and corresponding conclusions and recommendations which can be used as a reference for similar projects are drawn.
