A state-of-the-art summary of recent developments in the behaviour, analysis and design of seismic resistant steel frames. It provides advanced students, researchers and professionals in civil and structural engineering with the basic principles which the modern seismic codes are based upon. The book is much more than a simple background volume, because it also gives the most recent results which can be used in the near future to improve the codified recommendations for steel structures in seismic zones. All recent developments in seismic design of steel frames are dealt with. The book...
