摘　　要：长春室内滑雪场建筑总长度约443.4m,通过防震缝分为两个结构单元,高区单元长度231m,低区单元长度211m,宽度从直段64.8m渐变为弧段最宽131m再递减。该建筑采用框架-剪力墙结构体系,滑道以上采用高大框排架柱支承大跨度管桁架屋盖。该工程两个独立结构单元均为超限高层建筑,存在扭转不规则、层刚度比偏小、塔楼偏置、斜柱、错层、竖向尺寸突变等不规则结构。介绍了该类结构的宏观体系优选方法,以及上部结构设计的重难点分析,如结构抗侧力体系的合理布置,边排大柱、跨中大柱、斜柱、屋盖体系等特殊构件的类型优选,超长结构温度应力的分析要点,抗震性能目标的确定及分析方法,确保了上部结构体系、构件及连接节点形式的合理性及可靠性。The total length of the Changchun indoor ski resort is about 443.4 m,which is divided into two structural units through the seismic joint.The length of the high-zone unit is 231 m,and the low-zone unit is 211 m.The width gradually changes from the straight section of 64.8 m to the widest section of 131 m and then decreases.The building adopts frame-shear wall system,and the roof of long-span pipe truss is supported by tall frame column above the ski run.The two independent structural units of the project are both out-of-code high-rise buildings,which have irregular torsion,low inter-story stiffness ratio,tower offset,inclined column,staggered floors,vertical dimension sudden change and so on.This paper introduces the macroscopic system optimization method of this kind of structure,as well as the analysis of the important and difficult points in the design of superstructure,such as the specific and reasonable arrangement of the lateral force resistance system of the structure,the type selection of special components such as large side columns,straddle columns,inclined columns,roof system,etc.,and the key points of the analysis of temperature stress of ultra-long structures.The determination and analysis methods of seismic performance targets ensure the rationality and reliability of the superstructure system,components and joint forms.
