    CSP as a structural member

    If you check the link I supplied, it is manufactured in a spiral formation, hence it's not quite as "pre-buckled" as you think. The supplier gives a moment of inertia in mm^4/mm, which I'm told is called the pipe wall moment of inertia. I'm additionally unclear of how to use this type of...

    CSP as a structural member

    Sorry -- Corrugate Steel Pipe -- the steel code doesn't cover it, as it is not typically used as a structural member. It is very convenient to use it though! The CSP I'd like to use is found at: http://www.big-o.com/catalogue/Culverts%20Drainage%20and%20Stormwater/Hel%20Cor.pdf They give a...

    CSP as a structural member

    I'm a junior water guy -- does anyone have experience calculating failure modes of CSP as a structural member? I'm using CSP to protect/support a watermain across a bridge with piers spaced 4m apart. I wish to verify deflection in that span, and yield condition. Do I use wl^2/8 for max moment...

    Standard PVC bends

    Yep, 11.25 is the smallest. As you said, 22.5, 45, 90. That's it. Stan

    Does anyone have experience calculating failure modes of CSP as a structural member? I'm using CSP to protect a watermain across a bridge with piers spaced 4m apart. I wish to verify deflection in that span, and yield condition. Do I just use wl^2/8EI for max moment and l^3/48EI for deflection...
