Seismic response of a continuous foundation structure supported on partially improved foundation soil
Abstract The response of a continuous foundation structure supported on partially improved foundation soil was recorded during an earthquake. The measured results show that partially improved foundation soil can induce torsional response of the foundation due to the irregular soil-foundation system. A numerical model considering soil-structure interaction was then established, and the numerical results were compared with the observation data. Using the validated numerical model a parametric study was carried out to investigate the torsional response of a continuous foundation structure with irregular soil foundation system. It can be concluded from the study that eccentricities in the soil foundation system would result in a torsional response. Particularly with different lengths of soil-cement piles in the partially improved foundation soil, the generated torsional response can not be ignored during the seismic excitation.
Highlights The response of a structure supported on improved foundation soil was investigated. Study was carried out to analyze the torsional response of a continuous foundation. For the foundation partially improved, torsional foundation motion will be generated.
