摘要
钢结构人行天桥由于其自重轻,因此对外部激励的振动效应更加明显。在一定的条件下,桥上的行人会由于结构振动而产生不舒适感或不安全感。然而,目前我国有关设计规范中,没有给出人行天桥的振动舒适度评价指标。参考国外相关规范中关于人行天桥舒适度的评价标准,并结合工程实例,论述相关评价标准在人行天桥减振加固设计中的应用。
The vibration effect of external excitation is more obvious to the steel structural pedestrian overpass because of its light deadweight. The pedestrian on overpass will feel discomfort and insecurity under a certain condition. However, there are no vibration comfort evaluation indexes of pedestrian overpass in the relative design standards in China now. Referring the evaluation standards of overpass comfort in the foreign standards and combining with the engineering practices, the article discusses the application of relative evaluation standards in the vibration reduction and reinforcement design.
