S960 Ultra-High Strength Steel Welded I-Section Structural Members provides detailed theoretical and experimental data on the key design provisions for ultra-high strength steel structures. Most of the current design provisions for high strength steel welded I-section components with material grades up to S690 (or S700) have been developed by those for normal strength steel counterparts. The design parameters of S960 ultra-high strength steel structures – which are increasingly being used in structures - is out of their scope and this book addresses that omission.

• Most of the current design provisions for high strength steel welded I-section components are for material grades up to S690 (or S700). Information on the design of S960 ultra-high strength steel structures is not available
• Testing, numerical modelling and design analysis of S960 ultra-high strength steel welded I-sections under pure compression, pure bending and combined loading are covered in detail in the book. The relevant assessment results provide the basis for the further development of effective design rules in different countries
• Investigates the structural performance of S960 ultra-high strength steel welded I-sections, but and also covers other cross-section profiles and extreme conditions, e.g., fire conditions
