Liquefaction-Induced Settlements of Residential Buildings subjected to Induced Earthquakes
Yannis Chaloulos, Amalia Giannakou, Vasileios Drosos, Panagiota Tasiopoulou, Jacob Chacko and Sjoerd de Wit have co-authored a paper titled: “Liquefaction-Induced Settlements of Residential Buildings subjected to Induced Earthquakes” which will be soon be published in Soil Dynamics and Earthquake Engineering. The paper evaluates the dynamic performance of existing residential houses affected by gas-extraction-induced earthquakes in an area of low tectonic seismicity where structures have not been designed against earthquake loading. Nonlinear, effective stress, fully coupled, dynamic soil-structure interaction analyses were performed to develop estimates of liquefaction-induced settlements for buildings on narrow spread footings covering a range of soil conditions, ground motions and structural characteristics that are typically encountered in the study area. A simplified equation was developed from regression of the numerical analyses results to derive estimates of liquefaction-induced settlements for residential buildings that was adopted in the latest update of the relevant seismic building code. The paper has been accepted and is under production. Stay tuned!
