【摘要】 为保证框架-核心筒结构双重抗震防线的安全,中国规范对外框架按照刚度分担的剪力比例进行了限制,实际设计过程中,很多工程很难满足规范限值要求。对该体系双重抗震防线的相关研究进行了梳理总结,分别从震害、振动台试验和数值分析角度进行了阐述,指明不同研究方法在该问题上存在的不足和局限性。讨论了当前研究中存在的问题和对执行规范过程中的不同理解;从基于性能抗震设计的角度,提出双重抗震防线应达到的合理目标,并对今后应开展的研究和主要焦点进行了展望。

【Abstract】 To ensure the double earthquake fortification lines’ safety of frame-core tube structure,the distribution ratio limits of shear force in external frame calculated according to the stiffness was proposed in Chinese code.In the actual design process,it is difficult to meet the specification limits for many engineering projects.In this article,from the earthquake damage,shaking table test and numerical analysis point of view,related studies about the double seismic defence line of frame-core tube structure were summarized,and the deficiencies and limitations of different studies on the problem are specified.The issues that exist in the current study anddifferent understandings of the specification were discussed.Based on the performance-based seismic concept,the reasonable target of double seismic defence was proposed,and the research that should be carried out and the main focus have been prospected.
