Truss: It is defined as a framework, typically consisting of rafters, posts, and struts, supporting a roof, bridge, or other structure.
Truss can be classified as follows:
a) Simple Truss: It consists of a series of triangles so that the weight being supported is distributed evenly to the supports.
∴ A truss will be classified as a simple truss if m = 2j – 3.
b) Complex Truss: It is not necessarily a set of the triangle as the members may overlap each other.
c) Compound Truss:
It is formed by connecting 2 or more simple truss together. Often, this type of truss is used to support loads acting over a larger span as it is cheaper to construct a lighter compound truss than a heavier simple truss.
Various type of compound truss are as follows:
Type 1: The trusses may be connected by a common joint & bar.
Type 2: The trusses may be joined by 3 parallel bars.
Type 3: The trusses may be joined where bars of a large simple truss, called the main truss, have been substituted by simple truss, called secondary trusses.
