User:Rib truss

Rib truss noun  A Rib truss is a single cell truss unit appearing similar to a "picture frame." The unit utilizes a moment-resistive corner assembly created to resist racking. The rib truss is intended to be placed in a linear module; i.e. 5'-0" on center, eliminating the need to transfer the lateral forces to an end wall or shear wall diaphragm.

The interior of the truss is void of webs to allow functions, such as living space, work activity or storage to occur in the center.

Rib trusses can be built of wood, steel, plastic or a host of various materials with various means of applying moment resistance in the corners. The corner materials can be either the same material of the Rib truss itself or a different material.
