Abstract

The utilisation of ultra-high strength steel can significantly improve the resisting strength and efficiency of steel and composite structures, it thus is a potential solution for modern high-rise construction. However, an in-depth understanding of the local buckling behaviour of ultra-high strength steels is still needed due to the lack of specific design standards. In this paper, a series of finite element analysis for local and post-local buckling behaviours of hollow and composite stub columns incorporating high and ultra-high strength steel was presented. The steels used in the analysis have nominal yield stresses of 690 and 960 MPa. A finite element model was developed by using the com..
