Behaviour and design of composite columns utilising high strength steel plate for tall buildings

High strength quenched and tempered structural steel has had an important niche usage in the application to heavily loaded columns in multistorey building construction. Many current international codes do not cater for the use of high strength steel and thus much needed research is required to give structural engineers the confidence to use this new and innovative material in a safe and efficient manner in construction. Previous research on the use of high strength structural steel for columns is outlined herein. The paper provides a comprehensive summary of experimental results on the use of high strength structural steel in composite columns. Calibration of these experiments with theoretical models and the Eurocode 4 approach have highlighted some of the differences that need to be implemented in order to design structures safely with this material
