大跨异形人行拱桥舒适度分析及TMD减振控制

摘要:

综合分析了现有规范对舒适度分析的规定要求,结合国内外规范确定了大跨异形人行拱桥舒适度分析流程。同时对桥梁结构进行了TMD减振控制分析,对比分析了阻尼器的质量、刚度以及布置形式等因素对舒适度的影响,提出了阻尼器布置的合理方案,对相似工程可以提供一定参考。

Abstract:

This paper comprehensively analyzes the requirements of existing specifications for comfort analysis, and determines the comfort analysis process of long-span special-shaped pedestrian arch bridge in combination with domestic and foreign specifications. At the same time, the TMD vibration reduction control analysis of the bridge structure is carried out, the influence of the mass, stiffness and layout form of the damper on the comfort is compared and analyzed, and the reasonable scheme of the damper layout is put forward, which can provide a certain reference for similar projects.
