Seismic Design Principles

This lecture covers the importance of special standards for existing structures, emphasizing the need for seismic safety. It discusses seismic zones, ground types, analysis methods, and the structural system for horizontal actions. The presentation also delves into the seismic design of new structures, the seismic assessment of existing structures, and compliance factors. The instructor explains the individual and collective risk criteria, acceptable safety costs, and the concept of non-deterioration in seismic retrofitting.
