【摘要】 提出高层建筑大跨度拱架结构的概念,介绍了拱架结构在多个高层建筑项目中应用的关键技术及研究重点,着重阐述了广州报业文化中心1号连廊的结构设计与分析。为满足建筑空间及结构安全要求,76m跨度连廊采用内置型钢的钢筋混凝土筒体支承的钢管混凝土拱架混合结构体系,对拱架结构的动力特性、整体稳定、抗震性能、楼盖舒适度、关键节点及施工模拟进行研究,并采取相应的加强措施,解决了拱架的整体稳定性、拱脚推力的承担及舒适度控制等关键问题。更多还原

【Abstract】 By presenting the concept of large-span arch structure in high-rise buildings,the key technology and research focus of several arch structure buildings were introduced. The structural design and analysis of the 1# corridor of Guangzhou Daily Group Culture Center were mainly described. To meet the architectural space and structural safety requirements,the76 m span corridor building adopts concrete filled steel tubular arch mixed structure system supporting by reinforced concrete tube with H-shaped steel column inside. Through research of structural dynamic characteristics,overall stability,seismic performance,vibration serviceability,important nodes and construction simulation,the problems of overall stability,thrust bearing of arch foot and vibration control were solved with the corresponding strengthening measures.更多还原
