框架-核心筒结构柱网布置方案比较

摘要

The paper adopts the frequent earthquake mode-shape decomposition response spectrum and elastic time-history dynamic analysis,cal-culates and researches the two layout schemes for the frame-core tube structure’s column casing,analyzes its various stressed features and their influence on the architectural functions,and indicates the addition of internal columns can improve the design for the floor structure and lower the buildings’story height,while the scheme without the column can lower the seismic response and exert the anti-lateral motions rigidity of the core tube,and illustrates some measures including the one-way multi-ribbed beam and wide-flat beam in the design for the floor system can lower the beam height.%采用多遇地震振型分解反应谱法和弹性动力时程分析法，计算研究了框架—核心筒结构柱网的两种布置方案，分析了其不同的受力特点和对建筑使用功能的影响，指出采用增设内柱方案有利于楼盖结构的设计和降低建筑层高，而采用不设内柱方案可降低结构的地震反应，且能有效发挥核心筒的抗侧刚度优势，楼盖结构设计时可采取单向密肋梁、宽扁梁等措施来降低梁高。
