某结构主楼高152.4m,采用框架核心筒结构形式,文中重点介绍了结构布置、抗震设防性能目标、计算分析和性能设计等内容,通过小震弹性和时程分析、中震性能设计和稳定性分析、大震弹塑性分析等计算手段找出结构的薄弱部位,并采取相应的抗震加强措施,可为同类超限结构的抗震设计提供参考。
The main building of a structure with a height of 152.4m adopts the frame core tube structure. The article mainly introduces the structural arrangement, seismic fortification objectives, calculation and performance design, etc. Through the analysis of the minor vibration and time history, the performance and stability Analysis, plastic analysis of large earthquakes and other computational means to find the weak parts of the structure and take corresponding measures of seismic strengthening can provide references for the aseismic design of similar overrun structures.
