Motion Analysis on Overturning Behavior of Furniture Using ASI-Gauss Technique



Improperly secured furniture, especially on the upper floors of high-rise buildings under long-period ground motion, can become dangerous objects for human life. In this study, we developed an effective numerical code to analyze the overturning behaviors of furniture subjected to seismic excitation with the adaptively shifted integration (ASI) – Gauss technique. The frictional contact between objects was fully considered by employing a sophisticated penalty method. A basic evaluation was carried out by comparing the results of certain experiments with analyses of motion behaviors of steel cabinets excited by sine waves.
