Introduction to High Beams and Strut-And-Tie Model

High beams are structural elements that play a crucial role in reinforced concrete construction, such as shear walls, couple beams, pile caps, and head pillars over the bridge. These elements are designed to withstand significant shear loads, and their voltage and strain behavior tends to be nonlinear. The Strut-and-Tie Model (STM) method is a common choice for analysis and design of high beams due to its ability to provide a better understanding of the flow of voltage and the distribution of force in the concrete structure.
