Site-specific Spectral Response of Seismic Movement due to Geometrical and Geotechnical Characteristics of Sites
Abstract It is well-known that the response of a site to a seismic solicitation depends on local topographical and geotechnical characteristics. Many aspects of seismic site effect still need to beExpand
