Roof Truss Nodes

Electrical and telecom towers are the one of the simplest example that we are seeing in the day to day life.

Roof truss nodes. The wall plate width see figure 7. The highest point on a truss where the sloping top chords meet. 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. A roof truss is a triangular wood structure that is engineered to hold up much of the weight of the rest of the roof.

A slight vertical cut usually less than 75mm at the. 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. Although this rigorous definition allows the members to have any shape connected in any stable configuration trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes. Space frame truss contrast to planar truss the members and the nodes are located in the three dimensional space.

A horizontal cut to the bottom of a sloping bottom chord usually the width of the bearing i e. These trusses are most often used as the roof trusses. A modified warren truss may be adopted where additional members are introduced to provide a node at for example purlin locations. Structural support of trusses usually walls normally with a timber wall plate.

Planar truss as the name implies it is a two dimensional truss. Bearing cut or seat cut. A roof truss is a structural framework of designed to bridge the space above a room and to provide support for a roof. This type of truss is also used for the horizontal truss of gantry crane girders.

Roof trusses are created by attaching the ends of members to joints known as nodes.
