[摘要] 提出适用于超高层建筑新型结构体系：巨型柱一芯筒骨架结构。骨架结构是在矩形框架的基础上发展起来的，适合一些建筑外形复杂，沿高度立面变化较多的复杂、不规则的超高层建筑。通过对该结构体系静力弹塑性分析，追踪结构破坏的全过程，了解结构的薄弱楼层和构件，从而对结构的抗震性能进行了评估，结果表明该结构体系是一种抗震性能优越的超高层建筑结构体系。

Abstract: A new super lugh-rise structural system known as the mega column-core tube skeleton structure is proposed. The skeleton structure is further developed in foundation of rectangular frame, suits irregular super-high building of some architectural complex appearances and surface change highly complex along sets up.  In this paper, by means of Push-over analysis of the structure system, track the whole processes of structure breakage, meanwhile understand structure weak floor and frame, and so can evaluate structure aseismic performance; moreover results illustrate that the structure r is one
kind of superior extra-high building structure system.
