Introduction to the MG1 General Method of Eurocode 2 for the Design of Concrete Columns: Foundations, Usage Limitations, and Key Points of Attention.
The general method for column design according to Eurocode 2, and more specifically the simplified option of this method, referred to as MG1 in this document, is an important everyday tool for the reinforced concrete structural engineer. It makes it possible to significantly reduce the theoretical complexity of studying a slender reinforced concrete column or wall, by approximating second-order effects.
However, this method has usage limitations and caution points that can sometimes be difficult to master, especially since spreadsheet implementations—commonly used in design offices—may hide certain important concepts.
This four-part dossier offers a review of the different calculation steps of the general method, with a focus on various influential aspects. This Part 1 provides a reminder of the fundamentals of the general method.
