摘要：超高层建筑的高度越来越高，建筑功能逐渐综合化，建筑体型趋向于复杂化，给结构设计带来很大挑战。从超高层建筑锥形体型的发展趋势，对建筑锥形体型与超高层结构设计的关系进行了阐述。首先，锥形体型建筑可以充分利用结构材料，减少建筑物风荷载作用，尤其是横风向动力响应。其次，锥形结构布置可有效提高结构抗侧力体系的效率。再次，锥形结构布置能够提高结构的整体性能，如结构稳定、外部框架结构刚度等。因此，锥形体型是超高层建筑功能与结构优化相结合的产物，也是今后超高层建筑结构设计发展的必然趋势。

Relationship between tapered shape and structural design of super high-rise buildings
Abstract: The height of super high-rise building is getting higher and higher, the building function is gradually integrated, and the building shape tends to be complicated, which bring great challenges to structural design. From the development trend of tapered shape of super high-rise building, the relationship between building tapered shape and structural design of super high-rise building was expounded. Firstly, the tapered shape building can make full use of structural material, and reduce the wind load of building, especially the crosswind dynamic response. Secondly, the tapered structure arrangement can effectively improve the efficiency of lateral force resisting system. Again, the tapered structure arrangement can improve the overall performance of the structure, such as structural stability, external frame structure stiffness. Therefore, the tapered shape is the product of the combination of function and structural optimization of super high-rise building, and it is also the inevitable trend of the structural design and development of super high-rise building in the future.
Keywords: super high-rise building; tapered shape; structural lateral force resisting system; overall stability
