如果忽略一些与建筑材料密切相关的概念不谈，高层建筑里最为常用的结构体系便可分为如下几类：1 U" b* m3 {7 {

Indeed, the better high-rise buildings carry the universal traits of simplicity of thought and clarity of expression.$ y9 X d5 [* o' h3 ]8 }$ B
It does not follow that there is no room for grand thoughts. Indeed, it is with such grand thoughts that the new family of high-rise buildings has evolved. Perhaps more important, the new concepts of but a few years ago have become commonplace in today’ s technology./ g3 B9 V+ V! f) B n
