桥梁用液体粘滞阻尼器检测方法探讨

近年来随着减隔震技术在桥梁中的应用日益增多,液体粘滞阻尼器作为一种减隔震措施的重要装置在桥梁工程尤其是大跨特殊桥梁中应用越来越多。国内外阻尼器的生产厂家数量众多,层次不齐,我国目前对于阻尼器质量的检测尚无成熟系统的规范可循。本文以目前世界上较为先进的美国AASHTO中对于锁定装置的规定和欧洲规范EN15129中对速度型阻尼器的规定为基础,结合工程实际应用,探讨了桥梁用液体粘滞阻尼器的相关规定和检测方法,可为设计时桥梁上使用的阻尼器质量控制提供参考。

Study on the detection method of liquid viscous dampers for Bridges

In recent years, with the increasing application of vibration reduction and isolation technology in Bridges, liquid viscous dampers, as an important device of vibration reduction and isolation measures, have been applied more and more in bridge engineering, especially in special long-span Bridges. There are a large number of domestic and foreign manufacturers of dampers, and the levels are not uniform. There is no mature system to follow for the quality detection of dampers in our country. Based on the advanced American AASHTO for locking devices and the European code EN15129 for velocity dampers, this paper discusses the relevant regulations and testing methods of liquid viscous dampers used in Bridges, which can provide reference for the quality control of dampers used in bridge design.
