Types Of Wood Roof Trusses

Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge.

Types of wood roof trusses. Below are the common types of roof. These steel joints are needed to support the overall truss. The cord size and web configuration are determined by span load and spacing. It is usually used for roof construction some common trusses are named in accordance with their web configuration.

This method allows for greater energy efficiency. Steel rods are used as tension members. There are two fundamental types of trusses i e. This particular truss is made out of wood most of the time but it can also be built out of a combination of steel and wood.

The raised heel roof truss reduces. As the name implies this roof appears flat in structure although it is always pitched at a wider angle to allow water runoff. Commonly used in cathedral ceilings the cost of this truss is higher because it requires. It is usually built of wood completely or of wood combined with steel.

Total load psf duration factor live load psf roof type 55 1 15 40 snow shingle 55 1 15 30 snow tile 47 30 snow 40 20 snow 1 25 20. Pitched truss or common truss characterised by its triangular shape. Common types of roof trusses parallel chord roof truss. The same thing is true for the bridge of the truss.

The more complex the truss framework is the greater quantity of these joints will be required. The shapes and spans shown here represent only a fraction of the millions of designs produced by alpine engineers. Most common types of roof trusses gable trusses. Alpine truss designs are engineered to meet specific span configuration and load conditions.

The king post truss is mainly adopted for short spans less than 6 m. Another very common roof type the hip truss is used to create a hip roof which has slopes on all four sides.
