［摘要］由于建筑功能的要求，在沈陽中匯廣場SOHO塔樓的5層樓面處需對較多外框架柱進(jìn)行結(jié)構(gòu)轉(zhuǎn)換，根據(jù)其特殊的平面布置情況，最終采用Y形斜撐轉(zhuǎn)換形式。詳細(xì)分析了Y形斜撐的受力特點(diǎn)，給出了其適用條件及設(shè)計(jì)要點(diǎn)。結(jié)構(gòu)整體計(jì)算分析結(jié)果表明，該塔樓采用Y形斜撐轉(zhuǎn)換能滿足規(guī)范要求和預(yù)先設(shè)定的抗震性能目標(biāo)；同時(shí)對轉(zhuǎn)換構(gòu)件進(jìn)行了中震和大震作用下的有限元應(yīng)力分析，并根據(jù)分析結(jié)果提出了可行的設(shè)計(jì)加強(qiáng)措施。

Abstract: Considering the requirements of architectural functions, many outer frame columns should be transformed on the fifth floor of SOHO tower of Shenyang Zhonghui Plaza. According to its special structure layout, Y-shaped transfer diagonal brace was adopted. The mechanical behavior of Y-shaped diagonal brace was analyzed in detail. The application condition and key design points for Y-shaped transfer diagonal brace design were introduced. The integral structural calculation and analysis results show that the structure with the Y-shaped diagonal brace can meet the code requirements and the performance-based seismic design goals. The stresses of transfer components under the medium earthquake and the rare earthquake were analyzed using the finite element method and the feasible strengthening measures were proposed based on the analysis results.
Keywords: super high-rise building; Y-shaped diagonal brace; transfer story; strengthening measure
