A completely revised and updated in-depth guide to the requirements central to earthquake-resistant design of steel structures Ductile Design of Steel Structures, Third Edition has been thoroughly updated to address the extensive advancements made in the industry over the past decade. The book covers steel material, cross-section, component, and system response for applications in plastic and seismic design and provides practical guidance on how to incorporate these principles into structural design. You'll find essential coverage of new structural systems like composite steel plate and concrete-filled walls, as well as new ductile connections for special moment resisting frames, and modifications in the design requirements for other structural systems. This third edition is filled with new and updated content, including: * Essential information on concrete-filled composite steel plate walls (SpeedCore) * A significantly expanded chapter on buckling restrained braced frames * Updated knowledge recently implemented in the AISC seismic provisions that has simplified the design of steel plate shear walls * Design examples that comply with requirements in the 2022 AISC provisions * New information on load-path in floor/roof diaphragms, from the inertia force sources to the lateral force resisting systems, and general information on diaphragm design * Information on new structural systems being proposed, such as friction devices, scorpion-braces, and more Written by experts in earthquake-resistant design who are active in the development of seismic guidelines, this is an invaluable resource for practicing engineers and graduate students in structural engineering.
