摘要

Through the wind-included response analysis, the distribution law of root-mean-square of joints wind-included vibration response is acquired. Wind-included response of hangar under mean wind load and fluctuating wind load separately is compared and the influence of the wind direction angle to the results is discussed. In addition, the power density spectrum of joints wind-included response is analyzed is this paper. It shows that background component is the main part of joint displacement while the main part of joint acceleration is resonant component.
