I have a pipe that is fixed to a base plate and the base plate is anchored to a concrete floor. There are a set of rollers at the top of the pipe (the end furthest from the anchored end) and a second roller set on the opposite side of the pipe anywhere from 48" to 70" below the top roller set. Bending and deflection on the pipe is a no brainer but I am having trouble determining if the roller forces could exceed the bearing strength of the pipe or could cause the pipe to cripple at the roller location. This is especially a concern on pipes as big as 30" OD and wall thickness as small as 5/16". Another issue I need to solve is how much the pipe will indent and how much the rollers compress so I can calculate the force required to move these rollers about the pipe. I know I can get the deformation of the rollers from Hertz contact stress equations but the pipe is what I am having trouble with. I'm not asking for a solution, I'd just like to be pointed to some references that may address the issues I am having so I can fully understand what I need to do. A drawing is attached to illustrate what I am babbling about. Any responses/ constructive criticism would be greatly appreciated. I'm not sure if the image uploaded or not so let me know if it didn't and I will try again.
