SUMMARY

The discussion centers on determining the torque required to secure a 31-meter high stack composed of three sections, with the bottom two sections measuring 10 meters each and the upper section 11 meters. Each section has a thickness of 12mm and an outer diameter of 950mm. The assembly utilizes 24 M20 high tensile galvanized nuts and bolts, and it is crucial to calculate the appropriate torque to prevent structural failure, especially since the stack is free-standing without additional support.

PREREQUISITES
  • Understanding of torque calculations for structural applications
  • Familiarity with M20 high tensile bolts and their specifications
  • Knowledge of material properties relevant to stack stability
  • Experience with free-standing structures and their engineering requirements
NEXT STEPS
  • Research torque specifications for M20 high tensile bolts
  • Study structural engineering principles related to free-standing stacks
  • Learn about load distribution in multi-section structures
  • Explore safety standards and regulations for tall structures
USEFUL FOR

Structural engineers, construction professionals, and safety inspectors involved in the design and assembly of tall, free-standing structures.

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...

Indeed it does. Thread closed.
