PhD Shuang Niu
University of Sydney
Shuang received his Bachelor degree with first-class honour, from Central South University (China), in 2006. He proceeded with study in structural engineering in Harbin Institute of Technology (China), and was awarded Master degree with title of Outstanding Graduate. Since October 2009, Shuang has been working in Uni Sydney as a PhD student, and his research topic is on coupled instability of thin-walled stainless steel structural members.
Stainless steel was historically restricted from vast use in structural application due to its high material price and absence of efficient design guides. During the past decades, however, with the raising awareness of its additional benefits and introduction of design codes, stainless steel is gaining increasing popularity in structural engineering.
Deriving from its highly nonlinear stress-strain behaviour, stainless steel members behaves quite differently from normal carbon steel. One of the key issues is the coupled instability behaviour, which is not well understood yet. Triggered by the need of design code revision, one on-going research project is aiming to remedy above mentioned issue. As part of this research, some experimental and FE simulation work are to be reported and results to date demonstrated. Some primary conclusion will be drawn from them.
