Seismic design of a complex tall frame-core tube structure beyond the code-specification:case studies of the main tower of an economic park in Hangzhou

为了研究复杂超限高层结构的抗震设计方法,本文以杭州某179.10m高层框架-核心筒主塔楼为例,通过对该结构进行抗震设计确定了体系的平面布置,并提出了核心筒和外围框架设计等关键问题处理和超限应对措施。通过分析结构超限情况确定了基于抗震性能化的设计目标,采用多个设计分析软件对结构进行了小震、中震和大震作用下的弹性分析和弹塑性动力时程分析,并对结构关键构件进行抗震性能验算。结果表明,该结构和各构件能够达到预定的抗震性能目标,可为复杂超限高层框筒结构设计应用提供参考。

In order to study the method of earthquake resistance design of complex super limits,this article takes a 179.10 meter high-rise frame-core tower main tower in Hangzhou as an example.The seismic design of the structure has been determined by the structure of the system.Design key issues such as handling and over-limit response measures.Through the analysis of the overtime situation of the structure,the design goals based on seismic resistance were determined,and the elastic analysis of the structure and the elastic dynamic dynamic timing of the structure under the action of multiple design analysis software was used to conduct the structure of the structure.Key components are calculated for seismic performance.The results show that the structure and components can achieve the predetermined seismic performance target,which can provide a reference for the complex super-limited high-level frame structure design application.
