典型高耸细长结构全仿弹性模型的风振研究

The Response of the Replica Elastic Models of Some Typical Outstanding Tall Slender Structures to Wind

以三种典型细高结构为研究对象，采用全仿弹性模型，进行了外形、质量分布、雷诺数和风结构等不同参数条件下的风洞实验。用应变仪测量了每种模型根部弯矩，通过计算，分析了模型风振响应的基本特性以及风振过程的混沌特性。

Several typical outstanding structure models were tested in a boundary layer wind tunnel,using replica modelling technique under conditions of several different experimental parameters---shape, mass distribution,Reynolds number,and wind structure. The bending moments were tested by the strain gauges.The response of these models to wind loads,including the chaotical characteristic in structure vibration procedure,was analysed.
