Non-linear behavior and design of steel structures

Frames are possibly the most common forms of man-made engineering structures. They are formed by joining one-dimensional members together. Since the early work of Euler, engineers started to realize that the strength of a member under compression does not only depend on the material yield stress, but also on the Young's modulus of elasticity. The introduction of steel material and other metals makes the consideration more important because of their relatively slender dimensions. From the vision of the current computer age, this paper is addressed to a review and summary of the work conducted on the non-linear analysis and design of steel frames in the past few decades.
