Strut-and-tie method deep beam
Apr 28, 2021 · Part 1 explores the basic concepts of the Strut-and-tie model (STM), and Part 2 attempts to describe the process of designing a pile cap using the Strut-and-tie model in 2D and 3D STM. The Strut-and-tie model (STM) is a generalization of the truss analogy, a concept used in shear design applied to all parts of the structure. For deep beam reinforcement and detailing, Eurocode 2 recommends using one of two design techniques. The first methodology is connected to the strut-and-tie model application and the second methodology is related to a linear elastic analysis using the finite element method.
