Abstract
Very high strength steel (VHS) is a quenched and tempered steel that has a nominal yield stress of 1350MPa, a magnitude that is 3 times that of common steel grades. This research aims at extending the use of this product from the motor vehicle industry where it is presently used, to the construction industry. A new type of concrete-filled column is proposed for this research. This paper reports on the stub column tests carried out on fabricated columns made up of very high strength (VHS) steel tubes and mild steel plates. The fabricated VHSplate columns that were tested were both empty and concrete filled. Failure modes observed in both the empty and concrete-filled fabricated VHS-plate stub columns are described. The strength of the empty and concrete-filled VHS-plate stub columns from the tests are compared to the strength obtained using formulae in existing literature and design standards. The results of this comparison are used to highlight directions for further study into this new type of composite column.
