The Effect of Local Site Conditions on Recorded Strong Earthquake Motions

Abstract

The subject of the effects o£ local soil conditions on strong ground motion is of particular interest now because of efforts underway to modify the building codes, new legislation concerning the aseismic design of hospitals, problems of earthquake-resistant design of nuclear power plants and a generally increasing sophistication of earthquake-resistant design procedures in structural engineering practice. As a result of these factors, many major projects now require geological and seismological studies, including some assessment of the expected earthquake motion at the site and an estimate of any probable effects of local site conditions on the expected motions.
