Technical Guidance Note (Level 2, No. 25): Designing for torsion in reinforced concrete elements

This Technical Guidance Note explains how rolled steel I and H-sections are designed to resist torsion.

Designing a post-fixed anchor (either resin-based or mechanical) can be a convoluted process - principally due to the number of variables involved when considering its use in any given situation.

A specialist contractor design item that is usually outside the responsibility of the structural engineer. However, in order to assess a truss design, the engineer needs to understand the theory underpinning it.
