［摘要］針對聯(lián)想泰倫廣場塔樓的復雜建筑需求，分別從施工工藝、造價、材料用量等方面綜合考慮，從3種結(jié)構(gòu)方案中比選出了一種相對最優(yōu)的結(jié)構(gòu)方案，即轉(zhuǎn)換層以下采用鋼筋混凝土框架-核心筒結(jié)構(gòu)，轉(zhuǎn)換層以上采用帶鋼結(jié)構(gòu)桁架轉(zhuǎn)換的方鋼管混凝土框架-核心筒結(jié)構(gòu)。分別從小震、中震、大震等方面進一步分析了結(jié)構(gòu)計算模型的合理性及結(jié)構(gòu)方案的可行性；由于結(jié)構(gòu)的復雜性及特殊性，針對結(jié)構(gòu)分析與設(shè)計時轉(zhuǎn)換桁架設(shè)置的必要性、塔樓結(jié)構(gòu)整體穩(wěn)定性、躍層柱的穩(wěn)定性等重難點問題進行了專項分析論證。結(jié)果表明，工程中采用的結(jié)構(gòu)方案達到了預定的性能目標的要求。

Abstract:Aiming at the complex construction needs of the towers of Lenovo Taylor Square, comprehensive considerations were made in terms of construction technology, cost, material consumption, etc., and a relatively optimal structural scheme was selected from the three structural schemes. Reinforced concrete frame-core tube structure was adopted below the conversion layer, and square steel tube concrete frame-core tube structure with steel structure truss conversion was adopted above the conversion layer. The rationality of the structural calculation model and the feasibility of the structural scheme were further analyzed from the aspects of frequent earthquake, moderate earthquake and rare earthquake. Due to the complexity and particularity of the structure, a special analysis and demonstration were conducted on the key issues such as the necessity of the conversion truss setting during structural analysis and design, the overall stability of the tower structure, and the stability of the cross-layer columns. The results show that the structural scheme adopted in the project meets the requirements of the predetermined performance objectives.
Keywords:Lenovo Taylor Square； comparison and selection of structural scheme; high truss conversion; elastoplastic time history analysis; construction simulation analysis
