“京广中心”高层钢结构工程设计介绍

INTRODUCE THE DESIGN OF JINGGUANG CENTRE-A STEEL TALL BUILDING

京广中心是北京最高的一幢多功能综合性钢结构建筑，它由塔楼、附楼和地下建筑三部分组成．塔楼为地下3层、地面以上52＋2层．这是一幢超高层的钢结构楼房，地面以上高度是208m．这幢建筑的基础是桩式筏形基础；地下结构采用了SRC结构；主要结构体系是由钢框架与预制RC剪力墙核心结构体系组成．结构分析是采用了三雏框架模型．

The JINGGUANG Centre is the tallest multiple-use building in Beijing. It consists of three blockes-tower block, annex building and substructure. Tower block is 3 stories under the ground and 52+2 stories above the ground. It is an extra-tall steel building with 208.0m height from the pround level. The fundation of this building is a piled raft; The steel reinforced concrete was used in substructure; Main structural system is the steel frame combined with a core structure system composed of precast reinforced concrete shear walls. The structural analysis is conducted the frame as 3-D structure.
