Liquefaction-induced settled isolated-footing-founded buildings in Taiwan

This database consists of 27 case histories of liquefaction-induced settlements of isolated-footing-founded buildings in Taiwan. The database covers the basic information of those buildings (e.g., building heights and widths), along with the liquefaction hazard indices (e.g., free-field ground settlements and the thickness of top non-liquefaction layer). The liquefaction hazards indices were evaluated by a liquefaction triggering analysis procedure (Hwang et al. 2021) and a post-liquefaction volumetric transformation model (Ishihara and Yoshimine 1992). The ground motion records (such as moment magnitude and peak ground acceleration) associated with the earthquake events which induced the building settlements are also covered by the database.
