Devices for protecting bridge superstructure from pounding and unseating damages: an overview
Previous earthquakes have highlighted the seismic vulnerability of bridges due to excessive
movements at expansion joints. This movement could lead to the catastrophic unseating …

Influence of ground motion spatial variation, site condition and SSI on the required separation distances of bridge structures to avoid seismic pounding
It is commonly understood that earthquake ground excitations at multiple supports of large
dimensional structures are not the same. These ground motion spatial variations may …
