提出适用于超高层建筑新型结构体系:巨型柱-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。
A new type of structural system suitable for super high-rise buildings is proposed: a giant column-core tube structure. The skeleton structure is developed on the basis of a rectangular frame. It is suitable for complex and irregular high-rise buildings with complicated shapes and varying degrees along the elevation. Through the static elasto-plastic analysis of the structural system, tracking the whole process of structural damage, and understanding the weak floors and components of the structure, the seismic performance of the structure is evaluated. The results show that the structural system is a kind of ultra-high-rise Building structural system.
