Coefficient called "structural factor" appears in building codes when calculation of wind loads in discussed. The wind load is proportional to this factor.
I have a lot of trouble understanding its meaning. One definition from here says:
The structural factor takes into account the absence of pressures simultaneity to the surface of the construction and of vibration of the structure caused by the turbulence.
Eurocodes, for example gave no clearer explanation. Could somebody explain the meaning in more detail? What is meant by "absence of pressure simultaneity", and how does a multiplicative factor account for this?
