Strut-and-tie modelling is a simple method of modelling complex stress patterns in
reinforced concrete as triangulated models. It is based on the same truss analogy as the design for shear in Eurocode 2 and can be applied to many elements. It is particularly useful where normal beam theory does not apply, i.e. where plane sections do not remain plane, e.g. in deep beams, corbels and pile caps. EC2 provides information about the use of strut-and-tie modelling and this article is an introduction for engineers who want to take advantage of this useful analysis method.
