摘　　要：超高层已成为城市发展中的重要建筑型式,而超高层结构体系的抗震性能是当前重要的关注之一。以某实际工程为例,通过“基于性能”地震分析计算平台OpenSees,建立相应的复杂超高层建筑结构有限元模型,并通过基于现场微振动检测技术的动力特性参数识别验证所建立模型的合理可靠性。进而,开展地震作用下结构动力响应分析,主要从基底剪力、层间位移角、结构顶点位移以及损伤破坏等方面进行探讨。研究成果可为复杂超高层建筑结构的抗震设计提供技术支持。Super high-rise building has become an important structure type in urban development, and the seismic performance of the complex out-of-code high-rise structure system is currently a critical concern. The actual project of an international trade center in a city was taken as an example in this paper, and a finite element model of the complex super high-rise structure was established through the performance-based seismic analysis and calculation platform OpenSees. The reliability of the model was verified by the identification of dynamic parameters based on the in-situ micro-vibration detection technique. Dynamic response analysis of the structure under earthquake was then carried out, taking into consideration the base shear force, story drift ratio, displacement of structure top, and structural damage. The research results can provide technical support for the seismic design of complex super high-rise building structures.
