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

Applies To Product(s): AutoPIPE, Version(s): ALL Environment: N/A 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. See Also Modeling "Wind" - Load Case Bentley AutoPIPE
