Prolyte Campus blog: The triangular pattern of a truss
A while ago we received a question from a Prolyte user, concerning the connection of straight truss pieces. He was wondering whether it is important, when you connect trusses, to keep the diagonal pattern going. Does it have any safety value to have the meeting diagonals both up or both down instead of one up and one down?
To answer this question, first some basic information about truss needs to be explained. A truss has diagonals because the triangular shape is the only geometric shape which retains its shape when it is exposed to a load at connection points or joints, even if these joints are hinged. This image from the Prolyte BlackBook shows how it works. Only if one side is deformed a triangle loses its shape.
All Prolyte trusses are designed as ready-to-use modules with end braces. This guarantees there will always be a triangle shape in your pattern. For this reason, especially when longer truss spans are needed, truss modules of different lengths can be assembled without the need to pay respect to the continuity of the lattice structure. Fool proof assembly for your convenience.
