Abstract:Wujiang Rural Commercial Bank is a building with height of 148-8 meters and adopts frame-corewall structural system. Large-span steel structure with three floors height of the podium is supported by tree-shaped columns. There are out-of-code conditions of torsion irregularity, slab discontinuity and size mutation in the structure. Time-history analysis, Pushover analysis under rare earthquake, buckling analysis of steel structure and uneven settlement analysis were conducted according to the characteristics of the project, and ABAQUS software was used to conduct finite element analysis on key joints of the structure.The results show that the structure is safe and reasonable. Some corresponding seismic strengthening measures were proposed as well.
Keywords:super-tall building; tree-shaped column; buckling analysis; uneven settlement; Pushover analysis
