    Problem:

    Is the pressure used in a wind profile the basic pressure (i.e. acting on a plate), or do I have to adjust the pressure for a pipe when inputting the figure in AutoPIPE?

    Solution: 

    Yes for the wind profile you should calculate the pressure acting on a pipe or cylindrical shape including the shape factor. This pressure will be calculated and entered at different heights. Also enter the wind shape factor multiplier = 1.0. 

    Note: Using UBC and ASCE-7 wind methods, the wind profile is automatically calculated. 

    It is common practice to analyze at a minimum, wind loading for two non-concurrent directions typically X and Z (assuming Y vertical). However the wind could be acting in positive or negative directions like seismic so you may wish to analyze a minimum of four cases +/- X and +/- Z. If you have no gaps or non-linear features like friction then only two cases +X and +Z may only be necessary then create load combinations to include +/-X and +/-Z e.g. Gr+T1+W1 and Gr+T1-W1.
