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, the 76m 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.
Keywords:high-rise building; large-span arch structure; overall stability; arch thrust; vibration serviceability; construction simulation analysis
