［摘要］以一棟8度區(qū)150m高框架-核心筒結(jié)構(gòu)的超高層為例，分析了無伸臂、2層高錯(cuò)層交叉布置伸臂和1層高伸臂三種框架-核心筒結(jié)構(gòu)方案在小震和中震下的性能，并對(duì)比分析了不同方案的安全性、經(jīng)濟(jì)性和適用性。結(jié)果表明帶伸臂方案優(yōu)勢明顯：可有效降低核心筒墻體拉應(yīng)力，顯著提高結(jié)構(gòu)的安全性；大幅降低結(jié)構(gòu)造價(jià)，經(jīng)濟(jì)性更好；增加使用面積，適用性更好；2層高錯(cuò)層交叉布置伸臂較1層高伸臂在經(jīng)濟(jì)性和安全性上更優(yōu)。

Abstract:Based on a 150m  high super high-rise building with frame-corewall structure in the 8 degree seismic region, the behavior of frame-corewall structures without outrigger, with 1-story height outrigger and with 2-stories height staggered outrigger under frequent and middle earthquakes were investigated，the securities，economies and applicabilities were compared between different schemes. The results show that the outrigger can improve the performance of the frame-corewall structure. Specifically, the scheme with outrigger has obvious advantage including decreasing the tensile stress of the corewall effectively, improving the structure security obviously, reducing the cost dramatically, owning better economy, increasing the structure usable area and having better applicability. Additionally, compared with the frame-corewall structure with 1-story height outrigger, the frame-corewall structure with 2-stories height staggered outrigger exhibits better security and economy.

Keywords:8 degree seismic region; super high-rise building; outrigger systems; seismic performance; frame-corewall
