Sliding is recognized as a dominant response mode for unanchored stocky components in
nuclear facilities. Although unanchored components are themselves not safety-critical,
their interaction with safety-critical systems and components during earthquake shaking
can have significant consequences. It is therefore important to be able to accurately
estimate the peak sliding displacement demands on unanchored components so that
sufficient clearance is provided around them. In lieu of nonlinear time history analysis,
the ASCE/SEI 43-05 standard provides an approximate method to estimate the maximum
sliding displacement of sliding objects in nuclear facilities. The present paper assesses the
procedure of the approximate method and compares its results to those of nonlinear time
history analysis. The study finds that the ASCE 43-05 approximate method provides
conservative sliding estimates overall and that is based on the three components of 7
modified and 159 real earthquake motions used in this study. It is concluded that the
ASCE 43-05 approximate method offers reasonable sliding estimates of components in
nuclear facilities. / Thesis / Master of Applied Science (MASc)
