摘要: 西双版纳某项目 2 栋塔楼为超 B 级高度的高层建筑，采用钢筋混凝土框架￣核心筒结构体系。 针对塔楼特性对方案进行合理调整优化后，采用 YJK 和 MIDAS 软件对其进行多遇地震计算对比分析和弹性时程分析作为补充计算，采用 PERFORM￣3D 和 SAUSAGE 软件对结构进行罕遇地震动力弹塑性时程分析，通过量化的计算方法，找出薄弱构件并对其进行加强，对结构关键构件采用抗震性能化设计。 计算结果表明，对于高烈度地区200m 内超 B 级的高层建筑，建议柱、剪力墙、框架梁结构受力体系的框架￣核心筒结构优先考虑采用型钢构件作为加强层，一方面可以有效提高结构整体刚度，另一方面也可避免结构刚度突变；对核心筒长宽比、高宽比较大并在弱向设置剪力墙的钢筋混凝土结构，增设的剪力墙宜根据其对整体结构的影响程度设定性能目标并进行抗震性能化设计。

Abstract: The No. 2 tower building of a project in Xishuangbanna is a high￣rise building beyond B￣level height with RCframe￣corewall structural system employed. After reasonable adjustment and optimization of the plan according to thecharacteristics of the tower building， YJK and MIDAS software were used for calculation and comparative analysis underfrequent earthquake， and elastic time￣history analysis was used as a supplementary calculation. Dynamic elasto￣plastic time￣history analysis of the structure under rare earthquake were carried out by using two types of software including PERFORM￣3D and SAUAGE， and weak components were found and strengthened through quantitative calculation. Performance￣basedseismic design was adopted for key structural members. The calculation results show that， for the high￣rise building within200m beyong B￣level height in high seismic fortification intensity area， it is recommended that the frame￣corewall structurewith column， shear wall and frame beam structure is reinforced with steel members as the strengthening layer. On the onehand， the overall stiffness of the structure can be effectively improved， and on the other hand， the structural stiffnessmutation can be avoided. For reinforced concrete structures with large length￣width ratio and large depth￣width ratio ofcorewall and shear walls in the weak direction， performance targets should be set for additional shear walls according totheir influence on the overall structure and performance￣based seismic design should be carried out.

Keywords:super high￣rise building； steel reinforced concrete beam column； performance￣based seismic design； stiffnessmutation； strengthening layer
