Structural Factor Calculation

Structural factor calculation

cscd=1+2·kp·Iv(ze)·B2+R21+7·Iv(ze)

ze

Reference height in Figure 6.1. For structures where Figure 6.1 does not apply, ze may be equal to the height of the structure

kp

Peak factor defined as the ratio of the maximum value of the fluctuating part of the response to its standard deviation

Iv

Turbulence intensity defined in 4.4

B2

Background factor, allowing for the lack of full correlation of the pressure on the structure surface

R2

Resonance response factor, allowing for turbulence in resonance with the vibration mode
