    摘要:

    桥梁风工程是以大跨度桥梁抗风稳定性、风致振动及其控制为主要研究目的,为桥梁抗风设计提供理论基础、方法及手段的技术学科。近年来,大跨度和超大跨度桥梁的迅猛发展促进了桥梁风工程分析理论、试验方法和风振控制技术不断进步,取得了一系列新成果。围绕大跨度桥梁抗风设计中的主要问题,介绍和评述了2019年以来桥梁风工程在桥位风特性现场实测、大跨桥梁非线性颤振特性及计算理论、桥梁抖振计算理论、桥梁涡激振动计算理论及控制技术等方面的主要研究进展。

    Abstract:

    Bridge wind-engineering is an interdisciplinary that aims to study the aeroelastic stability of long-span bridges, as well as wind-induced vibrations and corresponding countermeasures, and provides theoretical basis, methods and techniques for wind-resistant design of bridges. In recent years, the boom of long-span and super long-span bridges advances the development of bridge wind-engineering, giving rise to a series of achievement in both theoretical,test method and wind vibration control technolagy. Focusing on the main problems in the wind-resistant design of long-span bridges, this paper introduces and reviews the main research progress of bridge wind engineering in field measurement of bridge potential wind characteristics, nonlinear flutter characteristics and calculation theory of long-span bridges, chattering calculation theory of bridges, calculation theory of bridge vortex induced vibration and control technology since 2019.
