000019408 520__ $$2eng$$aThe New Zealand Canterbury Earthquake Sequence had several large earthquakes that produced different levels of liquefaction-induced ground failure and building damage. As a result, this earthquake sequence and the observations of seismic performance during it provide a unique data set for evaluating state-of-the-art design procedures. This paper focuses on the dynamic soil-structure interaction (SSI) analysis of a shallow founded building that suffered liquefaction-induced differential settlement in the Central Business District of Christchurch. The CTUC building was a 6-story reinforced concrete frame structure, with individual footings tied together by grade beams in both directions, which was demolished due to earthquake damage. Part of the building was founded over a buried stream channel filled with liquefiable silty sand. Nonlinear effective stress fully coupled SSI analyses were performed using FLAC-2D with the PM4Sand constitutive model calibrated with field and lab data. The results show good agreement between observed and calculated responses of the ground and the structure during the key events.
