In its 11th year, and reporting on the latest research on preparation for and mitigation of future earthquakes, this volume examines an area of increasing importance to many countries around the world. ERES 2017 assembled experts from around the world to present their basic and applied research in the fields of earthquake engineering relevant to the design of structures.As the world¿s population has concentrated in urban areas resulting in buildings in regions of high seismic vulnerability, we have seen the consequences of natural disasters take an ever-higher toll on human existence. Protecting the built environment in earthquake-prone regions involves not only the optimal design and construction of new facilities, but also the upgrading and rehabilitation of existing structures including heritage buildings, which is an important area of research.Major earthquakes and associated effects, such as tsunamis, continue to stress the need to carry out more research and a better understanding of these phenomena is required to design earthquake resistant buildings and to carry out risk assessment and vulnerability studies.Some of the subject areas covered are: Seismic isolation and energy dissipation; Building performance during earthquakes; Numerical analysis; Performance based design; Experimental studies; Seismic hazards and tsunamis; Safety engineering; Liquefaction; Innovative technologies; Paraseismic devices and Lifelines and resilience.
