Types of Roof Trusses and their Uses
Trusses are triangular steel sections which have been subjected to the essential axial forces because of the applied load externally. These triangular formations are used to span long lengths in exchange for solid web grinders. In this case, the loads of the building structures might lie on the three-dimensional plane, so the trusses are known as the space trusses.
Axially loaded members are used in trusses which can resist the load of building structures. On the roofs of single-storey industrial buildings and long-span floors, the trusses are usually used. The trusses are also used in the long span bridges which helps to carry the lateral load and gravity loads.
Different types of roof trusses
King Post Truss
These types of trusses are mainly used for short spans which are completely built of wood or wood combined with steel. In this case, steel rods have been used as the tension members.
Queen Post Truss
These types of trusses are also made with wood which is suitable for spans up to 10 m.
Howe Truss
The combination of wood and steel helps to form this type of truss. The vertical members of this type of truss are the tension members which are made of steel.
Fink Roof Truss
This type of truss is economical and suitable for ordinary buildings. In these types of trusses, the length of the compression members is small and the trusses are made with steel. This type of truss is also known as the French roof truss.
Pratt Truss
These types of trusses are generally used for flatter roofs which are made of steel. This type of truss is less economical as compared to the fink roof trusses.
