摘要
对一座大跨度人行钢拱桥进行有限元分析,并按照国外规范对该桥人致振动舒适度进行评价,分析结果表明该桥人行舒适度良好,在运行中不会发生过大的人致振动。结合分析结果对人行桥舒适度设计进行探讨,认为大跨人行桥竖向基频通常难以满足我国人行天桥规范要求,可参照国外规范进行舒适度评价。
A finite element model analysis for a large span steel arch footbridge was done, and the human -induced vibration comfort was evaluated in accordance with foreign specifications. The analysis results show that the Human - induced Vibration Comfort for the steel arch footbridge is well, excessive human - induced vi- bration will not occur during the operation. Combining with the results of the analysis discusses the design of pedestrian bridge comfort, it is believed that big span footbridge vertical base frequency is generally difficult to meet the requirement of pedestrian bridge in our country standard, and the human - induced vibration comfort can be evaluated with reference to foreign norms.
