The study first reviews some simple methods of calculating maximum
displacement, base shear and interstory drift from acceleration response records. A
record from a 17-story building in Los Angeles obtained during the Northridge
earthquake is used for illustration. More detailed analyses of similar records are
suggested as attractive subjects for Master's theses and senior projects. Simple analyses
of records from Northridge and other earthquakes convincingly indicate base shears and
drifts that are substantially in excess of those used in design. The author urges that
earthquake resistant design be based increasingly on measurements of earthquake response
and measured properties of materials, and less on empiricism and qualitative assessments
of earthquake performance.
