Abstract:The People’s Court of Nanjing Yuhuatai District has a structure height of 31. 65m and a plane size of 44. 4m ×49. 4m, it’s a reinforced concrete frame structure. Each floor of the third to seventh floors is cantilevered by 9. 1m alongthe west side. The structure of the cantilevered part is that the cantilevered steel beams extend from the frame columns. Atthe same time, a cable tie rod is set on the column to tie the distal end of the cantilevered steel beam, and a steel columnis set on the cantilevered end to form a spatial force-bearing system. The slabs on the second floor are largely missing,resulting in irregularities such as slab discontinuities and through-floor columns. Through PKPM and MIDAS softwares,elastic time history analysis, dynamic elastoplastic time-history analysis, anti-progressive collapse analysis, slab stressanalysis, slab comfort analysis were carried out. The results show that the structure meets the requirements of normalservice limit state and bearing capacity limit state, and the key components of frame column supporting diagonal tie rod,diagonal tie rod and cantilever steel beam meet the based-performance seismic goals, the structure is reliable and safe.

Keywords:People’ s Court of Nanjing Yuhuatai District;long cantilever structure; floor discontinuity; comfort analysis;buckling analysis
