Research review of lateral-torsional coupling considering soil- structure interaction

摘要

Structure would be in different extent of translational-torsional coupling due to the inconsistent of mass center and stiffness center which caused by the irregularity of floor mass and stiffness distribution. At present, the research on seismic response of the eccentric structure was not perfect, especially the translational-torsional coupling response considering soil-structure interaction. This paper briefly reviewed the research status on the lateral-torsional coupling considering soil –structure interaction effect and point out several problems existing currently in the field in order to make necessary preparations for analyzing seismic response of eccentric structure more in-depth.
