大跨人行天桥的自振频率初探

Elementary Discussion on Natural Vibration Frequency of Long-span Pedestrian Overpass

该文对各种常见人行天桥的自振频率进行了统计,并对其进行了力学分析,提出了提高其自振频率以满足强制性条文的措施,以供以后的设计参考。

The article counts the natural vibration frequencies of various common pedestrian overpasses, introduces its mechanics analysis, and puts forward the measures of increasing its natural vibration frequency to satisfy the compulsory provisions, which can be referred for the later designs.
