Abstract To overcome the limitations of the existing experimental methods (i.e., wind tunnel test and in-situ measurement) for wind engineering research of bridges, a new experimental method is proposed, i.e., studying the wind-resistant performance of bridges based on large-scale deck sectional models and full bridge aeroelastic models in natural wind. The representative wind field data are offered to briefly verify the feasibility of this experimental method. The Outdoor Experimental Bases for Bridge Wind Engineering of Dalian University of Technology as well as three full bridge aeroelastic models and a large-size steel tower (for deck sectional model and cable aeroelastic model tests) are introduced, and the extensive possible research items are listed. The available sensors and instruments are outlined, which enable many kinds of measurements. The advantages and disadvantages of the newly proposed experimental method relative to the existing ones are commented for deepen the understanding.

桥梁风工程研究新方法：自然风下大型气动弹性模型试验

摘要 为克服现有桥梁风工程研究试验方法（即风洞试验和原位测量）的局限性，提出一种新的试验方法，即基于大风量研究桥梁抗风性能。自然风中的比例甲板截面模型和全桥气动弹性模型。提供了具有代表性的风场数据，以简要验证该实验方法的可行性。介绍了大连理工大学桥梁风工程室外试验基地以及三个全桥气动弹性模型和一个大型钢塔（用于桥面截面模型和缆索气动弹性模型试验），并列出了广泛的可能研究项目. 概述了可用的传感器和仪器，它们支持多种测量。
