A Warren truss is a type of structural framework used in bridges and buildings. It consists of a series of equilateral triangles, which distribute loads evenly across the structure. This design helps to minimize material use while maintaining strength and stability. The key feature of a Warren truss is its ability to handle both tension and compression forces effectively. By using triangular shapes, the truss can efficiently transfer loads to its supports, making it a popular choice in engineering. Its simplicity and effectiveness have made it a common design in various applications, including civil engineering and architecture.
