［摘要］超高層建筑常常采用平面尺寸沿高度方向漸縮的體型，能非常有效地減小側(cè)向力，同時(shí)有效地控制豎向力的增長(zhǎng)，可以充分發(fā)揮結(jié)構(gòu)材料的強(qiáng)度和剛度，提高結(jié)構(gòu)的效率和經(jīng)濟(jì)性。結(jié)構(gòu)上采用豎向構(gòu)件沿建筑高度方向傾斜的形式，能達(dá)到結(jié)構(gòu)與建筑的融合，并避免復(fù)雜的水平轉(zhuǎn)換結(jié)構(gòu)。然而傾斜框架柱在轉(zhuǎn)折處會(huì)產(chǎn)生較大水平荷載，引起樓層梁、樓板及外環(huán)梁很大的受力。詳細(xì)分析了傾斜框架柱的受力特點(diǎn)和設(shè)計(jì)要點(diǎn)，以某400m以上的模擬超高層建筑為案例研究了其解決方案，驗(yàn)證了斜柱水平力的傳力途徑，并對(duì)樓面水平斜撐的設(shè)計(jì)進(jìn)行了探討。

Abstract: The plan sizes of super tall buildings usually decrease with increasing building height. It can reduce lateral load and vertical force effectively. What is more, strength and stiffness of structural materials are used sufficiently, improving economical efficiency. Vertical structural members incline to meet architectural requirement, avoiding complicated transfer level. However, there is large horizontal load in the floor where the inclination angle of columns changes, thus frame beams, floor slabs and external ring beams bear large force. Loading features and design points of inclined columns were analyzed in detail. A super tall building project taller than 400 meters was employed to illustrate solution method, and force transferring path of horizontal load generated by inclined columns was validated. Design of floor horizontal braces was also discussed.

Keywords: super tall building; inclined column; loading feature; design point
