摘要: 對(duì)于框架-核心筒超高層結(jié)構(gòu)而言,和傳統(tǒng)的有梁樓蓋相比,外框與核心筒之間采用不設(shè)明梁的平板樓蓋體系在降低建筑層高、改善建筑布置及提高施工效率等方面具有較為明顯的優(yōu)勢,但由于平板樓蓋體系節(jié)點(diǎn)抗震性能相對(duì)較弱,目前在高烈度區(qū)超高層結(jié)構(gòu)中的應(yīng)用還很少. 以北京通州某公寓主樓為例,針對(duì)框架-核心筒平板樓蓋體系結(jié)構(gòu)特點(diǎn),重點(diǎn)探討了從結(jié)構(gòu)體系認(rèn)定、結(jié)構(gòu)選型、結(jié)構(gòu)布置、設(shè)計(jì)難點(diǎn)、構(gòu)造措施及整體計(jì)算等方面對(duì)塔樓所采取的加強(qiáng)措施. 在小震反應(yīng)譜分析基礎(chǔ)上,補(bǔ)充進(jìn)行了中震下構(gòu)件承載力分析及大震下靜力彈塑性分析.結(jié)果表明,結(jié)構(gòu)各項(xiàng)指標(biāo)均比較理想,整體設(shè)計(jì)滿足結(jié)構(gòu)安全要求.

Abstract: For frame-core tube super high-rise structure, compared with beam-plate floor system, flat-plate floor systemwithout exposed beams between the outer frame and the core tube has obvious advantages in reducing the floor height ofstorey, improving architectural layout and construction efficiency. However, its application is less in high earthquakeintensity regions super high-rise building for its poor seismic performance. Taking a main apartment building in Tongzhou,Beijing as an example, according to the structure characteristic of flat-plate floor system, strengthening measures werecarried out, including the structural system identification, structural system selection, structural layout, design difficulty,structural measure and overall calculations. On the basis of response spectrum analysis under the frequent earthquake, thebearing capacity of components analysis under fortification intensity earthquake and the static elastic-plastic analysis underrare earthquake were conducted. Results show that structural indicators are ideal and the overall structural design satisfiessafety requirement.
Keywords:flat-plate floor system; super high-rise structure; frame-core tube; beam-plate floor system; high earthquakeintensity region
