一、课程内容简介 在各类钢结构设计中，保持稳定性是经常遇到的问题。从结构整体到构件再到局部板件，设计时无不涉及到稳定问题，这是钢结构设计的一个显著特点。其原因在于钢材的强度高，构件比较细长，组成构件的板件也比较纤薄，因而在压力作用下很容易失稳。对待钢结构中失稳的可能性，通常采用加以防止的对策，使结构、构件或板件不会因失稳而丧失承载能力；少数情况下则可以考虑板件的屈曲后强度，以获取较好的经济效果。因此，如何防止失稳和利用屈曲后强度，将是本课程的主要内容。

In each kind of steel structure design, we usually meets the problem that how to keep the stability. No matter the whole structure or the frame members, even the local components, design of them all involve the stability problem, which is a distinguishing feature of steel structure design. The reason lies in that the strength of steel is quite high, while the frame members are long and slender, and the components are very thin, so they intend to be buckling under the compression forces. To solve this problem, generally, it needs to prevent the structure, frame members and components from losing load-carrying capacity because of destabilization. On the other hand, the buckling strength also can be taken into consideration in certain cases for better economic efficiency. Consequently, how to prevent destabilization and make use of the buckling strength is the primary coverage of this course.
This course will mainly talk about the stability of axis compression members, bending members, bending-compression members, components, frames, arches and shells, and the grid structure. Relating the destabilization principles of each kind of members and components, it also includes the analysis on the rationality of every kind of the constitution measures and the array of structure. The course emphasizes on the explanation about the basic principle of the twisting destabilization and the crankle destabilization. To deal with the particularity of the grid structure, the content of much theorization is emphasized, too, such as the criterion of destabilization on the extreme point and the branch point, tracking strategy of the counterpoise path, and the path transition, etc.
Studying of this course can make students roundly understand the problems on stability that they may meet in the steel structrue design, comprehend the destabilization principle under various conditions, and master every kind of main theme of stability design, so that they can avoid the destabilization accidents effectively in designs and constructions.
