Tubular construction is synonymous with modern architecture. The familiar range of tubular sections, namely square, rectangular and circular hollow sections, has been recently extended to also include elliptical hollow sections. These new sections combine the elegance of circular hollow sections with the improved structural efficiency in bending of rectangular hollow sections, due to the differing flexural rigidities about the two principal axes. Following the introduction of structural steel elliptical hollow sections, a number of investigations into their structural response have been carried out. This seminar presents a state of the art review of recent research on elliptical hollow sections, together with a sample of practical applications. Details of full scale testing and numerical modelling studies are presented, and the generation of structural design rules, suitable for incorporation into international design codes, is outlined.


Tak-Ming is an Assistant Professor in Structural Engineering at the Hong Kong Polytechnic University and an Honorary Associate Professor in Structural Engineering at the University of Warwick, UK. He graduated from the University of Hong Kong in 2001 with a First Class Honours degree in Civil Engineering. He started his structural engineering career by joining Arup as a Graduate Structural Engineer. He received his Master's degree with Distinction in Structural Steel Design in 2004 and was awarded a PhD in the area of Tubular Structures in 2008 both from Imperial College London. In 2007, Tak-Ming was awarded the First Prize in the Young Researchers' Conference from the Institution of Structural Engineers (IStructE). His first PhD student sponsored by TATA steel also won the same prize in the 2012 competition. His second PhD student has won the joint-1st prize in the poster category in the 2013 competition. Tak-Ming is a Chartered Member of the IStructE, committee member of the UK mirror group for Eurocode 3 and the Education and Training committee of the HK Constructional Metal Structures Association. He is also an Associate Editor for the Advances in Structural Engineering Journal and a member of the Editorial Board for the Structures and Buildings Journal. Tak-Ming's research interests focus on the structural stability and resistance of metallic, concrete-metallic, pultruded FRP and smart structures under extreme events with particular emphasis on using an appropriate combination of experimentation, theoretical analysis and computational techniques to obtain knowledge for the development of design guidance.
