[摘要] 本文針對(duì)8度區(qū)高度超200m的某建筑結(jié)構(gòu)，通過大量計(jì)算分析及提出的四項(xiàng)評(píng)判準(zhǔn)則得出了采用筒中筒結(jié)構(gòu)體系是較合適結(jié)構(gòu)方案的結(jié)論；分析表明多筒結(jié)構(gòu)能有效緩解剪力滯效應(yīng)，從而極大增加結(jié)構(gòu)抗側(cè)剛度，大幅提高了該方案的最大可建高度；為在結(jié)構(gòu)底部獲得較大的柱網(wǎng)尺寸，采用了傳力直接、抗震性能優(yōu)越的斜撐桁架轉(zhuǎn)換結(jié)構(gòu)，并對(duì)其進(jìn)行了深入研究，提出轉(zhuǎn)換桁架上弦桿為偏心受拉構(gòu)件的觀點(diǎn)。

Abstract: A super high rise building structure with the height exceeding 200 meters in 8 degree areas is studied. By virtue of large amount of computation and presented four evaluation criteria, the conclusion is derived that the tube-in-tube system is the appropriate structural scheme. Analysis shows that the multi-tube structure can effectively relieve the shear lag effect. Then, the structural lateral stiffness is enhanced, and the maximum possible height of this building is raised greatly.  To obtain a larger column network dimension, the modified scissors truss transfemng structure is adopted since it can directly transfemng the force and its seismic performance is superior. Moreover, the modified scissors truss transfemng structure are investigated profoundly, and the viewpoint is presented that the top chord in the truss is a eccentrically tensile member.
