Abstract: The trial business building of Suzhou Intermediate Court has 7 floors above ground. The podium at the bottom isa square plane with a large hole in the atrium. The upper tower is an offset L?shaped plane. There are 12 through?layercolumns spanning 3 floors on the bottom of the south side and the east side. Structural plane and vertical are irregular,making the structure overrun. The structural design adopts a frame?shear wall structure system with three?area shear walltube arrangement according to the plane and vertical characteristics to ensure a certain torsional rigidity. Using SATWE andMIDAS Building software, two different models were established to conduct elastic response spectrum analysis and elastictime history analysis under frequent earthquake, and the results of the two methods were compared. The static pushovermethod was used to carry out the static elastic?plastic analysis of the structure under large earthquake, and the seismic shearforce and buckling stability analysis of the through?layer column were also carried out. The results show that the indicatorsmeet the requirements of the specification, the measures taken are feasible and effective, and the structural scheme has agood seismic bearing capacity.
Keywords:frame?shear wall; over?limit high?rise structure; shear wall cylinder; L?shaped plane; through column
