概述了近年来为支持大跨度悬索桥设计而开发的风洞活动和方法。考虑影响桥梁不同部分（主要是桥面和塔架）的气动现象，研究了风桥相互作用的最重要方面。实验活动和结果是在数值和实验方法之间的协同方法的框架内提出的，该方法代表了从风桥相互作用的比例再现开始定义桥梁全尺寸气动弹性行为的常用做法。静态和动态风荷载，气动弹性稳定性，涡激振动将被研究。(C) 2013 Elsevier Ltd.版权所有。
An overview of the wind tunnel activities and methodologies developed in the last years to support the design of long span suspension bridges is proposed. The most important aspects of the wind-bridge interaction are investigated considering the aerodynamic phenomena affecting the different parts of the bridge (mainly deck and towers). The experimental activities and results are proposed in the framework of a synergic approach between numerical and experimental methodologies that represents the common practice in defining the full scale aeroelastic behavior of the bridge starting from scaled reproduction of the wind-bridge interaction. Static and dynamic wind loads, aeroelastic stability, vortex induced vibrations will be investigated. (C) 2013 Elsevier Ltd. All rights reserved.
