Composite steel-concrete beams and columns fabricated with high strength steel (HSS) plate

High strength quenched and tempered structural steel has seen widespread implementation in heavily loaded columns in multistorey building construction. However, many current international codes do not cater for the use o f 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. Herein, experiments and analytical studies on composite steel-concrete composite beams and recommendations for modified . design procedures will be summarised. This paper will also provide a comprehensive summary of experimental results on the uses of high strength structural steel in composite columns specifically for multistorey building construction. Calibration o f these experiments with theoretical models and the Eurocode 4 approach have highlighted some o f the differences that need to be implemented in order to design building structures safely with this material. Suggested design recommendations as well as further research will therefore be addressed in this paper.
