In this work, a 3D model of an ancient statue -- the South Memnon Colossus, was built, and its dynamic response to sinusoidal earthquake motion was investigated. In the transient analysis, parametric studies were conducted to better understand the impact of ground motion characteristics (frequency, amplitude, and direction) on the structure’s seismic response. The comparison was made of the dynamic responses with and without soil-structure interaction effects. The analyses were conducted in MSUP (linear) mode of a commercial finite element code ANSYS. The solution was obtained in the frequency domain and showed increasing deformation as the load frequency approaches the natural frequency of the structure (resonance).
