Structural Steel Hollow Section Connections
- Tim Wilkinson
- Undergraduate thesis groups & postgraduate projects
The shape of hollow sections with the ability to only access one side of the section easily make the design of connections more complex than that of traditional I-shaped sections. In addition, design recommendations for some hollow section connections have been based on models for I-shaped sections when it is difficult to determine if the same design methodology can be extrapolated to hollow sections.
This project has been performed in conjunction with Smorgon Steel Tube Mills over a number of years and carried out predominately by undergraduate thesis students. The aim has been to compare hollow section connection behaviour with current Australian design practice, and where possible devise new formulations.
