［摘要］通過(guò)對(duì)重慶來(lái)福士廣場(chǎng)項(xiàng)目的風(fēng)氣候分析、復(fù)雜地形風(fēng)洞試驗(yàn)、多天平風(fēng)洞試驗(yàn)、高頻壓力積分試驗(yàn)與第三方風(fēng)洞試驗(yàn)，得到了等效靜力風(fēng)荷載與加速度響應(yīng)，分別采用頻域與時(shí)域方法分析了復(fù)雜連體多塔結(jié)構(gòu)的風(fēng)致響應(yīng)，并對(duì)結(jié)果進(jìn)行包絡(luò)設(shè)計(jì)。單塔結(jié)構(gòu)的測(cè)力天平與測(cè)壓試驗(yàn)結(jié)果吻合性較好，多塔連體結(jié)構(gòu)的第三方風(fēng)洞試驗(yàn)與原有試驗(yàn)的平均值與背景值吻合較好，說(shuō)明了試驗(yàn)方法的合理性。還在時(shí)域中采用LSDYNA對(duì)塔樓與連橋之間的隔震支座在風(fēng)荷載作用下的性能進(jìn)行了研究。分析結(jié)果為重慶來(lái)福士廣場(chǎng)項(xiàng)目設(shè)計(jì)提供了安全經(jīng)濟(jì)合理的設(shè)計(jì)風(fēng)荷載。［關(guān)鍵詞］重慶來(lái)福士廣場(chǎng); 地形風(fēng)洞試驗(yàn); 風(fēng)氣候分析; 復(fù)雜多塔連體結(jié)構(gòu); 多天平風(fēng)洞試驗(yàn); 時(shí)域分析中圖分類號(hào)：TU973.14，TU973.32 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)24-0029-08
Wind-resistant design of Raffles City in ChongqingZhang Zhengwei1, Alex To2, Andrew Allsop3, Francois Lancelot1, Feng Duoduo1(1 Arup, Shanghai 200031, China; 2 Arup, Hong Kong, China; 3 Ove Arup & Partners International Limited, London, U.K.)Abstract: The equivalent static wind loads and acceleration responses of Raffles City in Chongqing project were derived by doing researches involving wind climate analysis, complicated topography wind tunnel test, multi-high frequency force balance (MHFFB) wind tunnel test, high frequency pressure integration (HFPI) test and independent third party wind tunnel test. The frequency-domain analysis method and time-domain analysis method were used to analyze the wind-induced responses of complicated multi-tower connected structures, and then enveloped design was carried out on results. The test results of the HFFB and HFPI of the single tower are consistent with each other and the mean and background results from two different independent wind tunnel labs are also close to each other, which all justify the validity of test methodology. To check the performance of the seismic isolators between tower and linked bridge under wind loading, software LS-DYNA was used in time-domain analysis. The analysis results provide safe, economical and rational wind loads for the design of Chongqing Raffles City project.Keywords: Raffles City in Chongqing; topography wind tunnel test; wind climate analysis; complicated multi-tower connected structures; multi-high frequency force balance wind tunnel test; time-domain analysis.作者簡(jiǎn)介：張正維，博士，工程師，Email：zheng-wei.zhang@arup.com。
