【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,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]:Super-high-rise buildings often adopt the shape of plane size shrinking along the direction of height, which can reduce the lateral force very effectively, and control the vertical force growth effectively, which can give full play to the strength and stiffness of the structural materials. Improve the efficiency and economy of the structure. The vertical structure is inclined along the direction of the height of the building, which can achieve the integration of the structure and the building, and avoid the complex horizontal conversion structure. However, the inclined frame column will produce large horizontal load at the turning point, which will cause a large force on the floor beam, floor slab and outer ring beam. The stress characteristics and design essentials of inclined frame columns are analyzed in detail. A case study of a 400m high building is carried out to study its solution. The method of force transfer of inclined columns is verified, and the design of horizontal brace on floor is discussed.
