DETERMINATION OF THE WIND RESISTANCE ACCORDING TO THE LOADS AND THE DOWELS
Determination of maximum load on dowel.
Based on the dimensions of the structure and on the runner number, enter in the load tables 3,
4, 5 or 6 (according to the resistance at the desired wind speed) and identify the maximum
load on the single dowel. The obtained value is expressed in daN (1daN ≈ 1kg).
In the example below the input data are:
- Width: 550 cm
- Projection: 350 cm
- Runner number: 3
- Maximum desired wind speed: 49 km/h
Load comparison
The recommended load to be used as comparison is the
lower
one between the traction and the
shearing load.
The
lower
one between the maximum traction recommended load and the shearing one must be
higher than or
equal to the maximum load on single dowel identified from the load table relevant to the desired wind
speed. Vice versa, if the recommended load is lower than the maximum load on the dowel, assess the
following options: A) change the type of dowel
B) Duly reinforce the wall or the floor
C) Refer to a load table in case of a lower wind speed and assign the installed product to the relevant
wind resistance.
Attention
For a correct selection of the dowels,
exclusively refer to the manual provided by the fixing system
manufacturer.
