Plastic Analysis of Frames – A Complete Guide – Part 2

In the second part of this series on plastic collapse analysis, we explore how what we learned in part one can be applied the frames. Plastic analysis methods are particularly useful in the analysis of indeterminate steel portal frames as it allows us to efficiently achieve relatively large spans by allowing for the formation of plastic hinges and moment redistribution within the frame. By the end of this tutorial, you will be confident applying plastic analysis methods to very common single and double-bay frame structures.
