Discussion on Roof batten and optimizing nails

In what test that must be used before the start

According to the Australian Standards AS 4600 and AS 3566, it can be noted that thin steel batten and roof cladding are used mostly in low rise buildings in Australia. This is because they are extremely weak and can face any connection failure whenever there is a risk of any natural disaster. Moreover, the current design of roof batten is completely dependent on the full-scale prototype roof tests. Therefore, there is a need to apply a cyclic test to overcome the damage of the roof batten. For that case, a proper prototype design equation will be presented to overcome this problem in roof battens. For this case, a proper information can be taken from the Australian Standards AS 4600 and AS 3566 (Steel.org, 2020).

In full-scale tests, there are about two categories in which the roof batten cyclic tests are performed. The first one is a small scale isolated connection test and the next one is short batten tests. In that case, two-span roof panels are made with the help of different components. Another thing is that for this test the roof components must be proper otherwise there will be other failures like local dimpling. In this case, corrugated steel roof cladding material is used for minimizing this effect. Then after this, a proper series of constant amplitude cyclic load tests are performed with different load ranges (Hamakawa, 2012).

Minimum shear strength of roof batten

The main thing is that the minimum shear strength must be known for the proper construction of roof batten. It can be noted that there are a lot of materials are used for the construction of roof battens. The materials are selected for roof battens are according to the area. In different parts of Australia, there is always a risk of hurricanes and other natural disasters. Due to this case, there will be always a high risk of selecting materials for roof battening (Australia, 2020).

In single-story in Australia, according to the Australian Standards AS 4600 and AS 3566. The minimum shear strength of the steel used for roof battening is G559 steel with a base metal of 0.42 mm thickness and it also contains yield stress of 550 MPa. Moreover, it can be noted that its pullout capacity according to the Australian standard is about

Due to these standards, it will become easy to select the steel material for the construction of roof batten. Another thing is that there are different methods are given for the construction of roof battening in Australia (Hamakawa, 2012).
