超高层建筑结构选型及经济性分析

Analysis on Structural Selection and Economy of Super High-Rise Building

我国虽幅员辽阔,但人口众多,且随着城市化进程的不断发展,上亿农村人口涌入城市,使得人口更多地聚集于经济较为发达的城市中心,城市常住人口数量的不断攀升加剧了城市的用地紧张。在技术与经济高速发展的基础上,为解决人口与土地的矛盾,高层建筑、超高层建筑近年来如雨后春笋般不断涌现,同时也对超高层建筑设计提出了更高的要求,合理选择超高层建筑的结构形式并达到较优的经济性已成为超高层建筑设计的设计重点。本文总结了国内外当前最为常见的超高层建筑结构类别与结构体系,列举了其适用范围、特点,并进行简要的经济性分析,以期为今后超高层建筑设计提供一定的借鉴和参考。

China has a vast territory and a large population.However,with the continuous development of urbanization,hundreds of millions of rural population have poured into the cities,which make the population more concentrated in the economically developed urban centers,and the increasing number of permanent residents aggravates the tension of urban land use.On the basis of the rapid development of technology and economy,in order to solve the contradiction between population and land,high-rise buildings and super high-rise buildings have sprung up in recent years.At the same time,higher requirements are put forward for the design of super high-rise buildings.Reasonable selection of structural forms of super high-rise buildings and achieving better economy has become the design focus of super high-rise buildings.This paper summarizes the most common structural types and structural systems of super high-rise buildings at home and abroad,lists their application scope and characteristics,and makes a brief economic analysis,which provides certain reference for the design of super high-rise building in the future.
