    06. How to input a Wind profile using Wind Velocity instead of Wind Pressure in AutoPIPE?

    Applies To
    Product(s): AutoPIPE,
    Version(s): ALL
    Area: Load
    Original Author: Bentley Technical Support Group

    Problem:

    How can the pipe movement be greater than the support gap setting for wind load combinations in AutoPIPE?

    Solution: 

    AutoPIPE does not accept velocity profile input at this time. AutoPIPE does show the pressure profile and how it is calculated in load summary of the input listing. ASCE 7 defines wind speed as the nominal design 3-second gust wind speed at 33 ft (10 m) above ground for Exposure C category.=

    Note that Kz value is 1.0 at 33 ft. So Kz gives the velocity profile per ASCE-7.

    You may use a similar procedure, entering your own velocity profile, to compute the pressure profile in Excel and then input in AutoPIPE. Refer to ASCE-7 for actual tables or equations.

    Also one may search the internet for converters:
