Seismic Design Principles in Structural Codes
This chapter describes and discusses the concept of capacity design in the light of existing seismic codes, illustrating the evolution of seismic design principles throughout time, and explains the criteria that form the basis of EN 1998‐1:2004 (CEN, 2004a). Modern codes like EC8‐1 give the possibility to choose different ductility levels for a structure, providing different ductility classes. The use of performance‐based seismic design (PBSD) allows to design both new buildings or to upgrade existing buildings with an accurate and realistic understanding of the risks and economic loss that may occur in case of future earthquakes. EC8‐1 allows the design of buildings with base isolation, but this part of Eurocode 8 is still more informative than applicative, and requires additional guidelines. In Europe, there is also a code specifically devoted to the design, characterization and the acceptance criteria of anti‐seismic devices, namely EN 15129.
