Reinforced concrete structure in high--rise buildings because of the major, pillars of the building area ratio increasing, in high--rise buildings with reinforced concrete structure has been questioned, therefore, high strength steel will emerge as the times require, and in high--rise buildings using part of the steel structure and steel structure design of the theoretical research and construction has been fully the use of.%钢筋混凝土结构在超高层建筑中由于自重大,柱子所占的建筑面积比率越来越大,在超高层建筑中采用钢筋混凝土结构受到质疑,因此,高强度钢材使应运而生,并在超高层建筑中采用部分钢结构或全钢结构的理论研究与设计建造得到了充分的运用。
