Fire behaviour of slender, highly utilised, eccentrically loaded concrete-filled tubular columns

Our General Manager Structural Systems Dr Stephen Hicks and Finite Element Analyst Nandor Mago have published a peer-reviewed paper in the Journal of Constructional Steel Research. The paper investigates the fire performance of highly utilized and eccentrically loaded concrete filled composite columns with a slenderness greater than currently permitted for the simple calculation model in…

Fire performance of light steel framed floors in multi-storey residential buildings

HERA is currently working on assessing the fire performance of a typical New Zealand light steel frame floor of a multi-storey building with the aim to provide input into the fire section of the resulting design guide. As the first part of the research, an overseas experimentally-tested floor slab has been investigated numerically by advanced…

DIY vibration testing

The two most advanced design guides on floor vibrations are SCI Publication 354 and CCIP-016 for steel-framed buildings and reinforced concrete buildings, respectively. Both design guides permit engineers to predict the response of structures due to human-induced vibrations to enable comparisons to be made with acceptance criteria contained within standards such as ISO 10137. Standards…

Additive manufacturing & 3D printing in design and engineering

3D printing and additive manufacturing are two of the newest and most discussed topics in design and manufacturing in recent years. A component can be created in almost any shape using successive layers of material, making rapid prototyping and manufacturing a reality and bringing with it low one-off manufacturing costs. What impact can engineering analysis…
