Roof Truss Nodes

The straight lengths of wood known as members that roof trusses built with are connected with intersections that distribute the weight evenly down the length of each member.

Roof truss nodes.

Bearing cut or seat cut. A slight vertical cut usually less than 75mm at the. A roof truss is a triangular wood structure that is engineered to hold up much of the weight of the rest of the roof. Structural support of trusses usually walls normally with a timber wall plate.

These trusses are most often used as the roof trusses. The wall plate width see figure 7. The top beams in a truss are called top chordsand are typically in compression the bottom beams are called bottom chords and are typically in tension. Space frame truss contrast to planar truss the members and the nodes are located in the three dimensional space.

Planar truss as the name implies it is a two dimensional truss. A modified warren truss may be adopted where additional members are introduced to provide a node at for example purlin locations. Roof trusses are created by attaching the ends of members to joints known as nodes. A horizontal cut to the bottom of a sloping bottom chord usually the width of the bearing i e.

A planar truss is one where all members and nodes lie within a two dimensional plane while a space truss has members and nodes that extend into three dimensions. Electrical and telecom towers are the one of the simplest example that we are seeing in the day to day life. This type of truss is also used for the horizontal truss of gantry crane girders. The highest point on a truss where the sloping top chords meet.

A roof truss is a structural framework of designed to bridge the space above a room and to provide support for a roof.
