Aseismic Capability Prediction from Failure Data

by David M. Hopper, Hopper & Associates, Redondo, Beach, CA, USA,



Abstract: Forensic engineering evaluations of failures have produced a wealth of technical data. In this paper, evaluation of representative failure data from one practitioner provided relevant data from which item aseismic capability predictions could be made. This limited investigation documents the adequacy of existing aseismic design provisions. It suggests that a structure, mechanical item, or instrumentation device designed with adequate ductility is inherently capable of withstanding seismic excitation in the absence of adverse resonant amplification phenomena.
