［摘要］中國國學(xué)中心項目建筑內(nèi)部功能空間采用了高大空間堆疊的設(shè)計策略，導(dǎo)致建筑平面、空間關(guān)系復(fù)雜。主體結(jié)構(gòu)具有樓板不連續(xù)、局部穿層柱、較多夾層，以及部分豎向構(gòu)件不連續(xù)等多重結(jié)構(gòu)不規(guī)則性，通過采用設(shè)置支撐形成高效的抗側(cè)脊骨結(jié)構(gòu)，有效解決了抗震最不利的抗側(cè)剛度突變的問題。中國國學(xué)中心項目創(chuàng)新性地運用基于失效模式和可修復(fù)概念的性能化設(shè)計方法處理此類復(fù)雜結(jié)構(gòu)，并通過相關(guān)的分析、試驗驗證了結(jié)構(gòu)具有良好的抗震性能，體現(xiàn)出了結(jié)構(gòu)設(shè)計的先進(jìn)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
