Although there have been many advancements in building construction technology in general. Spectacular archievements have been made in the design and construction of ultrahigh-rise buildings.5 q5 C# W- m8 D9 p4 b- E
The early development of high-rise buildings began with structural steel framing.Reinforced concrete and stressed-skin tube systems have since been economically and competitively used in a number of structures for both residential and commercial purposes.The high-rise buildings ranging from 50 to 110 stories that are being built all over the United States are the result of innovations and development of new structual systems.. m: i4 }; u! c) ]/ O% Z5 U7 P

近年来,尽管一般的建筑结构设计取得了很大的进步,但是取得显著成绩的还要属超高层建筑结构设计。! m- o j# V# R! \+ a
最初的高层建筑设计是从钢结构的设计开始的。钢筋混凝土和受力外包钢筒系统运用起来是比较经济的系统,被有效地运用于大批的民用建筑和商业建筑中。50层到100层的建筑被定义为超高层建筑。而这种建筑在美国得广泛的应用是由于新的结构系统的发展和创新。5 x% j6 M! i" j; J; S. N1 p
