[摘要]中国国学中心项目建筑内部功能空间采用了高大空间堆叠的设计策略,导致建筑平面、空间关系复杂。主体结构具有楼板不连续、局部穿层柱、较多夹层,以及部分竖向构件不连续等多重结构不规则性,通过采用设置支撑形成高效的抗侧脊骨结构,有效解决了抗震最不利的抗侧刚度突变的问题。中国国学中心项目创新性地运用基于失效模式和可修复概念的性能化设计方法处理此类复杂结构,并通过相关的分析、试验验证了结构具有良好的抗震性能,体现出了结构设计的先进性。

Abstract: The internal functional space of China National Culture Center project adopts a design strategy of stacking tall and large spaces, resulting in a complex relationship between the building plans and spatial space. The main structure has multiple structural irregularities such as discontinuous floor slabs, cross-layer columns, many interlayers, and discontinuous of some vertical components. By adopting the setting braces to form an efficient anti-side spine structure, it effectively solves the problem of the most unfavorable anti-seismic side stiffness mutation. Performance-based design methods based on failure modes and repairable concepts were innovatively applied to China National Culture Center project to deal with such complex structures, and verified that the structure had good seismic performance through relevant analysis and tests, reflecting the advanced nature of structural design.
Keywords:China National Culture Center project; eccentric braces; rehabilitated structures; performance-based design; seismic design
