| 摘 要： | 当人行天桥的竖向自振频率不能满足规范要求的时候,需要对其进行减振设计,采用协调质量阻尼器(TMD)进行竖向减振设计是实用且有效的方法。该文介绍了竖向人群激振荷载的选取和TMD参数的计算过程。最后以某人行天桥为例,计算了安装TMD之后桥梁结构的动力响应特性。

| Abstract: | It is required to implement the shock absorption design when the vertical self-vibration frequency of pedestrian overpass can not satisfy the standards.It is practical and efficient to implement the vertical shock absorption design by using the tuned mass damper(TMD).The article introduces the selection of vertical crowd vibrating loads and the computation process of TMD parameters,and finally computes the dynamic response characteristic of bridge structure after installation of TMD by a case of pedestrian overpass. |
