      Hi,

      I'm currently designing the support for a long and heavy channel as follows:

      I wanted to know which Standard is used for calculating this kind of support, specially wind loads, taking into account that they're going to be about 18-20m high and of course as thick as possible. I'm free for the design and the profile choice.

      Hope somebody can help,

      Best regards,

      You can figure wind loads using basic coef of drag and drag force equations. Apply a moment arm for the pipe and assume the center of load for the uprights is at center of bar. If you have access to a CFD simulator such as ANSYS CFX or Fluent you can get more accurate results. Don't for get to do a simple buckling calculations of the thin slender beams.

      If it's for a real project with real ppl hanging around you'd better consult an engineering firm. 18 to 20m looks like a challenging design especially looking at the section of the beams. This can not be done hastily and without careful study.

      Otherwise check for the Eurocode 9
