S960 Ultra-High Strength Steel Welded I-Section Structural Members provides detailed, theoretical, and experimental data on 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 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, hence this book addresses that omission.

• Explores current design provisions for high strength steel welded I-section components for material grades up to S690 (or S700)
• Includes updates on testing, numerical modeling, and design analysis of S960 ultra-high strength steel welded I-sections under pure compression, pure bending, and combined loading
• Provides 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 also covers other cross-section profiles and extreme conditions, e.g., fire conditions
