A freestanding rigid block subjected to base excitation can exhibit complicated motion
described by five response modes: rest, pure rocking, pure sliding, combined sliding …

Seismic base isolation performs well in protecting the drift‐and acceleration‐sensitive
elements in buildings, while its effectiveness in reducing the velocity response and thus …

With consideration of seismic resilience, damage of nonstructural components (NSCs)
attracts significant attentions. Most previous studies focused on dynamic behaviors of NSCs …

Near‐fault ground motions can impose particularly high seismic demands on the structures
due to the pulses that are typically observed in the velocity time‐histories. The velocity …

Vertical ground motions may increase irregularity of sliding response, while the subsequent
impact on the sliding fragility of building contents is not clear. Moreover, seismic risk of …

A novel intensity measure (IM), dimensionless floor displacement, is presented for
evaluating the seismic fragility of freestanding rigid blocks subjected to one-sine …

Motivated by the demand of seismic protection of museum collections and development of
performance-based seismic design guidelines, this paper investigates the seismic fragility of …

A freestanding rigid block subjected to earthquake excitation is a problem of significant
interest to the earthquake engineering community because it has many direct applications in …

Base isolation is accepted as the method of choice for mitigating the seismic risk of critical
facilities, including hospitals. However, while many studies have confirmed the effectiveness …

This study aims to quantify the effect of the vertical component of ground motion on the
seismic response of sliding rigid blocks, in terms of maximum and residual displacements. A …
