［摘要］全面介紹了某轉(zhuǎn)換高層建筑的抗震設(shè)計與施工控制措施。根據(jù)該結(jié)構(gòu)的超限情況，在設(shè)計中有針對性地采取了比現(xiàn)行規(guī)范更嚴(yán)格的抗震措施，關(guān)鍵構(gòu)件采用抗震性能化方法設(shè)計；對轉(zhuǎn)換層進(jìn)行精細(xì)的有限元分析，以考察構(gòu)件的空間整體效應(yīng)；并對框支節(jié)點進(jìn)行了三維空間精細(xì)設(shè)計，同時制定嚴(yán)格的施工控制措施。實踐表明，本工程采取的超限設(shè)計對策和施工控制措施，可有效解決框支轉(zhuǎn)換結(jié)構(gòu)中的鋼筋密集、施工質(zhì)量難以保證等技術(shù)難題，確保該結(jié)構(gòu)達(dá)到預(yù)期的抗震性能目標(biāo)。

Abstract: The seismic design and construction control of a high-rise building beyond code-specification with transfer story were introduced. According to the conditions beyond code-specification, more strict anti-seismic measures than the current criterions were adopted, and a performance-based seismic design method was used to design the key components. Through the fine finite element analysis of transfer story, the overall effect of component space was investigated. Meanwhile, three-dimensional space fine design for frame-supported joints and strict construction control measures were used in design. Practice shows that the adopted measures in design and construction control can effectively solve the technical problems, such as the intensive construction of reinforcement for frame-supported transferring structure and the quality of construction, which can ensure the structure to achieve the earthquake performance objectives.

Keywords: high-rise building beyond code-specification; transfer; performance-based seismic design; frame-supported joint; three-dimensional space fine design; construction control
