［摘要］武汉长江航运中心项目6#楼建筑高度163-50m，采用剪力墙结构体系，为B级高度高层建筑。结构同时具有扭转不规则、楼板不连续和刚度突变等超限不规则项。针对不规则，结构设计采用了相应的措施，并对该结构进行了静力弹塑性和大震动力弹塑性时程分析。计算结果表明，大震作用下结构层间位移角满足规范限值，构件状况符合预设的性能要求，整体结构满足并优于预期的性能目标。

Abstract:The 6# building of Wuhan Yangtze River Shipping Center project is 163-50m high and adopts shear wall structural system. It is a high-rise building with B grade height required by code. There are several out-of-code irregularities in the structure including torsional irregularity, discontinuous slab and stiffness mutation. The corresponding measures in the design were adopted for the irregular structure, and the static elasto-plastic and dynamic elasto-plastic time-history analysis of the structure were carried out. The calculation results show that under the action of rare earthquake, the interlayer displacement angle of the structure satisfies the specification requirement, and the component condition accords with the preset performance requirement. The overall structure meets and performs better than the expected performance goal.

Keywords:out-of-code high-rise building; shear wall structure; seismic performance; static elasto-plastic time\|history analysis; elastic-plastic time-history analysis
