Technical Guidance Notes (Level 3)

This note discusses axial shortening within vertical concrete loadbearing elements in structures with more than 15 storeys.

This note introduces the analysis and design methods for post-fixed anchors and explains how they can be applied. 

The purpose of this Technical Guidance Note is to assist structural engineers familiar with the theoretical behaviour of steel structural elements subject to torsion to avoid or design for it when necessary.

This note will explain how to determine the movement, or restraint to movement under thermal effects, and how it varies depending on a variety of conditions. It will also highlight areas where potential issues can be overlooked.
