What torque is needed for a stack?

  1. Nov 4, 2014 #1
    Hi can you please tell me hoe to determine the torque needed on a stack to prevent it from coming lose. the stack is 31m high and is divided into 3 sections.the bottom 2 pices are 10m high each and is 12mm thick with an outer diameter of 950mm. the upper section is 11m high with a thickness of 12mm. we will be using 24 M20 high tensile galvanized nuts and bolts to bolt the sections together. there are no supporting cables to hold up the stack it is free standing.

    thanks for your help

    This sounds super dangerous if you don't know what you're doing...
