Skewed bridges are susceptible to seismic damage due to their complicated dynamic
responses. A range of potential retrofit strategies have been implemented to mitigate …

Girder unseating in skewed bridges with seat-type abutments has been frequently observed
in past earthquakes. This has been attributed to excessive in-plane rotation of the …

The unseating of decks is one of the most prevalent failure modes of bridges after
earthquake events, as observed in the 2010 Chile Earthquake. Damaged bridges in Chile …

This paper presents an experimental program performed to investigate the behavioral
characteristics of unbonded steel‐reinforced laminated elastomeric bearings (U‐SLEBs) …

This paper presents a probabilistic seismic assessment of older and newly-designed
skewed multi-frame reinforced concrete box-girder bridges in California. The overall system …

Laminated elastomeric bearings have been widely used for small-to-medium-span highway
bridges in China, in which concrete shear keys are set transversely to prohibit large girder …

Seismological aspects of rotational ground motions can be found in published research,
however, studies on implications for the seismic response of structural systems are rare. This …

It is well known that skewed bridges with seat-type abutments are more vulnerable to
unseating during strong earthquakes than straight bridges of the same length, due to …

The unique dynamic response of skewed bridges causes them to experience more
noticeable damage compared to straight bridges during seismic events. The effectiveness of …

When a structure is isolated by rubber bearings and viscous dampers, some of those
bearings are often destroyed by an earthquake, causing a rough friction interface with large …
