The development in the construction industry has made engineers, architects and designers very creative and ambitious in building projects. The designs are becoming innovative and attractive. To achieve this, tremendous amount of weight placed was on materials leading to their inability to bear this significant weight. Consequently, to be able to achieve the structural design and strength engineers developed the truss. Trusses are web-shaped structures that are able to bear tremendous weight. They are used in buildings and bridges of all sizes. Trusses allow engineers to extend the dimensions of structures and create interesting shapes. Roof truss design is a structural framework mainly triangular in shape, used to bridge the space above a

The lumber trusses are of high quality and are able to tolerate high amount of stress as they are stress rated by machines. Where as plates are sturdy pieces of galvanized steel, used to hold wood together at joints. Plates help transfer stress from the wooden beams of the tress to the joint. This allows the truss to tolerate more weight.
All construction structures make use of trusses because of the additional support and strength that they provide. Triangular shapes are stable because the length of the sides of the legs and the measure of the angles correlate, making it difficult for triangles to lose their shape. Trusses are able to resist the force of a great deal of weight because a downward force applied to the corner of a triangle can be easily diffused throughout the shape. This sturdy feature of triangles makes this roof truss design structure common in engineering and architecture.
Different types of Wooden and Steel Roof Trusses:
• King Post Truss: is mainly a wooden truss. But can be built in combination of both wood and steel. It can be used for spans upto 8m.
• Queen Post Truss: is a wooden truss and can be used for spans upto 10m.
• Howe Truss: is made of combination of wood and steel. Where the vertical members or tension members are made of steel only. It can be used for spans from 6-30m.
• Pratt Truss: is made of …show more content…
• Fan Truss: is made of steel and is a form of fink roof truss. In this the top chords are divided into small lengths to provide support to purlins. It can be used for spans from
