 With loads measured in tens of thousands kips, there is little room in the design of high-rise buildings for excessively complex thoughts. Indeed, the better high-rise buildings carry the universal traits of simplicity of thought and clarity of expression.
 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.
 Omitting some concepts that are related strictly to the materials of construction, the most commonly used structural systems used in high-rise buildings can be categorized as follows:
 1. Moment-resisting frames.
 2. Braced frames, including eccentrically braced frames.
 3. Shear walls, including steel plate shear walls.
 4. Tube-in-tube structures.
 5. Tube-in-tube structures.
 6. Core-interactive structures.
 7. Cellular or bundled-tube systems.

 如果已经能够数千万磅重荷载，那么在高层建筑设计中就没有多少可以进行极其复杂的构思余地了。确实，较好的高层建筑普遍具有构思简单、表现明晰的特点。
 这并不是说没有进行宏观构思的余地。实际上，正是因为有了这种宏观的构思，新奇的高层建筑体系才得以发展，可能更重要的是：几年以前才出现的一些新概念在今天的技术中已经变得平常了。
 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． 抗弯矩框架。
 2． 支撑框架，包括偏心支撑框架。
 3． 剪力墙，包括钢板剪力墙。
 4． 筒中框架。
 5． 筒中筒结构。
 6． 核心交互结构。
 7． 框格体系或束筒体系。
