Ristikkorakenteita, known in English as truss structures, are structural systems composed of interconnected elements, typically straight members, that form a rigid framework. These members are usually connected at their ends by joints, often called nodes. The defining characteristic of a truss is that the individual members are primarily subjected to axial forces, meaning they are either in tension (being pulled apart) or compression (being squeezed together). This efficient distribution of forces allows trusses to span significant distances and support substantial loads with relatively lightweight materials.

The basic triangular unit is fundamental to truss design. Triangles are inherently stable geometric shapes; when connected, they form a rigid structure that resists deformation. Common examples of truss structures include bridges, roofs, and towers. In bridge construction, trusses are used to create the deck or support structure, enabling the bridge to carry the weight of vehicles. In buildings, roof trusses provide support for roofing materials and transfer loads to the walls or columns. The design and analysis of trusses involve understanding the forces acting on each member and ensuring that the structure can safely withstand these loads. Various types of trusses exist, each with specific configurations and applications, such as Pratt, Warren, and Howe trusses, named after their inventors or structural patterns.
