摘要: 超高層建筑的高度越來(lái)越高,建筑功能逐漸綜合化,建筑體型趨向于復(fù)雜化,給結(jié)構(gòu)設(shè)計(jì)帶來(lái)很大挑戰(zhàn).從超高層建筑錐形體型的發(fā)展趨勢(shì),對(duì)建筑錐形體型與超高層結(jié)構(gòu)設(shè)計(jì)的關(guān)系進(jìn)行了闡述. 首先,錐形體型建筑可以充分利用結(jié)構(gòu)材料,減少建筑物風(fēng)荷載作用,尤其是橫風(fēng)向動(dòng)力響應(yīng). 其次,錐形結(jié)構(gòu)布置可有效提高結(jié)構(gòu)抗側(cè)力體系的效率. 再次,錐形結(jié)構(gòu)布置能夠提高結(jié)構(gòu)的整體性能,如結(jié)構(gòu)穩(wěn)定、外部框架結(jié)構(gòu)剛度等. 因此,錐形體型是超高層建筑功能與結(jié)構(gòu)優(yōu)化相結(jié)合的產(chǎn)物,也是今后超高層建筑結(jié)構(gòu)設(shè)計(jì)發(fā)展的必然趨勢(shì).

Abstract: The height of super high?rise building is getting higher and higher, the building function is gradually integrated,and the building shape tends to be complicated, which bring great challenges to structural design. From the developmenttrend of tapered shape of super high?rise building, the relationship between building tapered shape and structural design ofsuper high?rise building was expounded. Firstly, the tapered shape building can make full use of structural material,andreduce the wind load of building, especially the crosswind dynamic response. Secondly, the tapered structure arrangementcan effectively improve the efficiency of lateral force resisting system. Again, the tapered structure arrangement can improvethe overall performance of the structure, such as structural stability, external frame structure stiffness. Therefore, thetapered shape is the product of the combination of function and structural optimization of super high?rise building, and it isalso the inevitable trend of the structural design and development of super high?rise building in the future.

Keywords:super high?rise building; tapered shape; structural lateral force resisting system; overall stability
