[摘要]   目前我國(guó)在抗震設(shè)防烈度8度及以上地區(qū)已建的超過(guò)200m的超高層復(fù)雜結(jié)構(gòu)越來(lái)越多。寧夏萬(wàn)豪大廈位于銀川市，銀川市地處8度抗震設(shè)防區(qū)，地震分組為第二組。萬(wàn)豪大廈主體結(jié)構(gòu)是由五星級(jí)酒店和四星級(jí)酒店豎向疊加而成的一棟50層的復(fù)雜超高層建筑，主體高度216m，目前為寧夏自治區(qū)標(biāo)志性建筑。本工程結(jié)構(gòu)存在超高、大底盤(pán)、平面和豎向均不規(guī)則、高位“人”字柱轉(zhuǎn)換等多項(xiàng)抗震不利因素，屬于超限復(fù)雜高層建筑結(jié)構(gòu)。結(jié)構(gòu)設(shè)計(jì)采用多種計(jì)算模型和計(jì)算程序?qū)ζ溥M(jìn)行反復(fù)分析和研究，并采取有針對(duì)性的抗震性能化設(shè)計(jì)及抗震措施。

Abstract：At present, there are a few super high-rise complex buildings higher than 200m in the seismic fortification intensity 8 degrees and above areas in our country. Marriott building is located in Yinchuan, and Yinchuan is located in 8 degree seismic fortification areas for the second earthquake group. The main structure is a 50-story super high-rise complex building vertically congruences by five-star hotel and four-star hotel, the high of main body is 216 m. At present, Marriott building is the landmark buildings in Ningxia autonomous region. The seismic unfavorable factors of this structure is super high-rise building, big chassis, horizontal and vertical irregular, high conversion inclined columns switching, so this structure is a overrun complex high-rise building structure. Many kinds of calculation models and programs were carried out to calculate and analyze for structural design, and targeted measures for seismic performance-based design and seismic were adopted.
Keywords：high-rise buildings; hybrid structure; high intensity areas; oblique column switching; rectangular steel tube column; performance-based seismic analysis
