[摘要] 洲頭咀A5 \A6 \A7棟樓為一大底盤(pán)多塔帶高位轉(zhuǎn)換的超限高層。本文主要對(duì)其結(jié)構(gòu)布置、抗震計(jì)算分析及結(jié)構(gòu)概念設(shè)計(jì)等方面進(jìn)行了介紹。針對(duì)其多塔高位轉(zhuǎn)換這一主要超限特點(diǎn)，采用了基于性能的抗震設(shè)計(jì)。經(jīng)多模型、多軟件的比較分析及彈性、彈塑性補(bǔ)充計(jì)算，保證設(shè)計(jì)能夠覆蓋結(jié)構(gòu)的各種實(shí)際受力狀態(tài)。對(duì)結(jié)構(gòu)的薄弱部位采取增強(qiáng)配筋，以及設(shè)置鋼骨梁、柱等特殊構(gòu)造措施，使結(jié)構(gòu)的抗震性能滿(mǎn)足規(guī)范及性能目標(biāo)的要求。

Abstract: The structural design of a high-rise three-tower building with large podiun beyond code linuts is introduced. The structural design, which includes structural plan, seismic analysis, seismic fortification measures and related conceptual design is introduced. For the design of transfer story beyond code limits, performance based seismic design was adopted. The seismic analysis results of multi-models using different analysis programs and the results oflinear and nonlinear time-history dynamic analysis are given to ensure all potential states of loading are enveloped. Some specific
constructional measures, such as adding steel bars and applying steel-concreate columns and steel-concrete beams, are taken to reinforce the weak positions to assure the design meets the performance objectives.
Keywords: super high-rise buliding; multi-tower building with large podiun; high transfer structure; performance based seismic design; elastic-plastic analysi
