Observation and research into the performance of steel structures during recent large earthquakes, such as those in Mexico City, Loma Prieta, Northridge and Kobe, has produced some very interesting results; not least in emphasising differences in the seismic effects of near-source and far-source earthquakes. Seismic Design of Steel Structures presents a critical review of the huge amount of technical information generated from these observations. The authors consider all types of steel structures, and present a new philosophy for their effective and safe design. In this new design philosophy, the direct checking of structural ductility plays a leading role. Real world applications and are described for different structural types and seismic characteristics, underlining the main features of each. Seismic Design of Steel Structures is a practical reference for all structural engineers involved in seismic design. It will be invaluable to researchers and postgraduate students of seismic structural analysis and design--
