抗侧向荷载的结构体系
抗侧向荷载的结构体系(中文3700字,英文2200字)
常用的结构体系
若已测出荷载量达数千万磅重,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。

Structural Systems to resist lateral loads
Commonly Used structural Systems
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. [来源:http://www.doc163.com]
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.
