PROFILE OF TURBULENCE INTENSITY AND TURBULENCE SCALE OF WIND BASED ON OBSERVATION DATA

Abstract

For the wind-resistant design of buildings, it is important to understand the fluctuation component of wind. In the AIJ Recommendation for Loads in Buildings (2004), the profile of turbulence intensity and turbulence scale are specified as constant up to a height Z_b, beyond which they are expressed by a power function of height Z. In the present study, the relationship between turbulence intensity or turbulence scale and observation height are discussed again, including new observation data. The scatter of observation data is also investigated.
