A strut is a structural component designed to resist longitudinal compression. Struts provide outwards-facing support in their lengthwise direction, which can be used to keep two other components separate, performing the opposite function of a tie.
Struts and props are vertical elements which support and transfer the load from the purlins to the strutting beams. Strutting beam. Strutting beams support the roof members where there are no load bearing wall studs available. They transfer the load of the roof to load bearing walls. Strutting beams should only support roof loads, and not be used as ceiling joists. Top plate: A top plate is nailed to the top of wall studs. This is the plate that the roofing elements sit on, and effectively the meeting point of the walls and the roof structure. It supports the roof load and helps transfer it down load bearing walls and into the foundations. Truss. A truss is a piece of framework using triangular shapes.
