S960 Ultra-High Strength Steel Welded I-Section Structural Members focuses on the structural behaviour and design of S960 ultra-high strength welded I-section components under different loading cases, with detailed introduction on experimental and numerical programme presented. The actual use of S960 ultra-high strength welded I-section components is restricted, to some extent, by the lack of appropriate design rules, since the current international design standards can only be applicable to steel components with material grades lower than S700 (or S690). Therefore, the applicability of the current design rules for high strength steel structures to ultra-high strength steel counterparts is evaluated and the relating efficient design approaches are proposed in this book, putting the basis for the development of current design codes.
