Design on a Hybrid Structure of International Financial Center Beijing Project/Zhang Xiangyong (China Electronics Engineering Design Institute,Beijing 100840,China)
Abstract:International Financial Center Beijing project is a complex highrise building structure with mixed structure system.Eccentricity located reinforced concrete in core leads to design difficulty.Many technical measures have been adopted to assure the seismic performance of this building.Now this project has gone through on seismic fortification sensor.
Keywords:complex highrise building structure; hybrid structure; story with outriggers and belt members; seismic fortification sensor; irregular; steel reinforced concrete
