# What is Truss Structure ? Definition, design and characteristics.

Truss is a structure that "has only two-force members, where members are organized so that together the convention acts as a single object." "Two-Force Member" is a structural component where force is applied to only two points. However, in this strict terminology, members are allowed to have any shape attached to any stable arrangement, including five or more triangular units directly formed in the truss, whose distance is attached to the joints, which are referred to as nodes.

In this typical context, reactions to external forces and those forces work only on the nodes and as a result, there are families that are either stressed or conservative. For direct members, moments are clearly excluded because, and only because all joints in Truss are considered revolutions, such as those required for links to two-force members.

Planar truss is the one where all members and nodes lie within a two-dimensional plane, while the space truss has members and nodes that extend into three dimensions. The top beam truss is called the top star and is typically in compression; the following beam is called the lower star and is especially stressed. Internal beams are called webs, and the inner areas of the web are called panels.

**Characteristics of Truss.**

**Simple Truss**

The easiest form of the truss is the triangle. This type of trouser is seen in mechanical structures such as chrome and roofed joists, bicycles, and aircraft. Triangles truss is known as a simple truss, by the method of analysis used to calculate this shape's stability and its inner forces. However, the smooth truss is often defined as more restricted, it is sought to be made by the successive pair of the memberâ€™s pair, which connects to each of the two joint joints and creates a joint with each other. And this definition does not require a smooth truss. Has only a triangle. Traditional diamond-shaped bicycle frames, which use two linked triangles, are an example of a simple truss.

**Planar Truss**

Planar Truss lives in the same plane. Planar trusses are usually used in parallel to create roofs and bridges. The depth of the truss, or the height between the upper and lower stars, makes it an efficient structural form. A solid girder or similar beam will have significant weight and material cost compared to Truss. For a given period, deeper trousers will need variables and more material in the diagonal. The maximum depth of the trace will maximize efficiency.

**Space Frame Truss**

Space Frame Truss is a three-dimensional framework for members, which are pinned at their end. A tetrahedron shape is a simple space, which consists of six members, which are found on four joints. A wide range of accelerated structures can be made of a tetrahedron with a common edge, and it is operating in the base structures of large free-standing power line pylons.
