Ristikkopalkit

Ristikkopalkit, also known as lattice girders, are structural elements formed by a web of smaller beams or bars connected in a triangular or diamond pattern. This configuration creates a rigid and lightweight structure that can span significant distances. The individual components are typically made of steel, wood, or sometimes reinforced concrete. The open, lattice-like design distributes loads effectively, making them highly efficient for their weight.

The principle behind ristikkopalkit is similar to that of a truss. By arranging the members in triangles, the forces are transferred along the lengths of the members, primarily as tension or compression, rather than bending. This leads to a greater strength-to-weight ratio compared to solid beams of the same depth. They are commonly used in building construction for roofs, bridges, and other applications where large, unobstructed spans are required. Their prefabricated nature can also speed up on-site assembly. The design can be adapted to various shapes and sizes depending on the specific structural demands.
