The main goal of analyzing the wind load is to convert it into a concentrated force which will be applied to the frames in order for us to start computation of moments and shears using any of the methods discussed earlier:
- Portal method
- Cantilever method
- Q-factor method
However, if you check the NSCP, the procedure with lead us only until which in units . This pressure (distributed load) is still to be converted into a force in order to be applied in the frame, thus will then be multiplied with an area,
. The area of which is the length of the wall being analyzed by the tributary height.
