Paper Abstract

Many organizations presently are evaluating the potential loss to plant, equipment and production capability in event of a major earthquake in their area. Often it is found that equipment can be protected at a fraction of the replacement cost. The paper discusses ground accelerations, seismic probability and certain characteristics of earthquake ground motion. Methods for determining loads from the Uniform Building Code and acceleration response spectrums are explained. Protection techniques for optical equipment are presented including rigid anchors, snubbers and sensing systems. The paper is for optical engineers and managers, with no particular background in seismology or structural engineering required.
