Structural Dynamics

In an event of an earthquake, source, path, and site characteristics as well as soil-foundation-structure interaction strongly a ects the seismic action to structures. Studies to understand these characteristics and their in uence, and risk evaluation considering the degree of in uence of each aspect, are conducted to reduce seismic disasters.
