Wind tunnel pressure coefficients obtained from the experiment, the pressure multiplied by the value of its reference points are the points of pressure upon the size. If the true demand simulated wind load building, then multiplied by the point of impact area and then multiplied by the scale of the square. this method? I calculated in accordance with the results of this method than by load code to calculate the wind load twice as big!!!
Since the ratio is calculated by loading the wind load specifications twice as big, and norms that shape coefficients compared to
can compare.
will be translated into the shape coefficient pressure coefficient. If the difference is also double the size factor, that calculation is no problem.
will pressure coefficients are translated into shape factor: if the wind field is B, the reference point height of 1.2m, the proportion of 1:200,
the height measuring point Zm (actual), and the wind pressure coefficient is normalized by the reference point of:
shape factor = wind pressure coefficient t (1.2 t 200 / Z) ^ (0.16 * 2)
other wind farms, such as C, then:
shape coefficient = pressure coefficient t (1.2 t 200 / 350) ^ (0.16 * 2) t (Z/400) ^ (0.22 * 2)
this method does not take into account your air pressure in space-related issues. To get the real equivalent static wind load, wind pressure at various points must be considered on the temporal correlation.
Therefore, consideration should be given at least one of sync because of air pressure reduction caused by the problem area.
