example 116.4 seismic load.
Why using n=43.5/h^(1/9) to obtain the first period (1/n), not using T=Ch^x? The results from the two equations are quite a bit, one is 0.85 and the other is 0.5x.
The former equation is mentioned in wind load, which has some more limitations, such as the height of building and wind direction.
