CALCULATION OF WIND RESISTANCE BASED ON THE LOADS AND THE ANCHORS
Based on the dimensions of the structure, consult the table below to identify the maximum load
on each anchor.

Based on the type of wall/floor on which the bolts will be fixed and using the manual of the fixing
systems manufacturer to determine which is most suitable.
Below we have indicated, purely as an indication, three examples referring to some extracts of HILTI
technical sheets which should be consulted for the correct choice and use of the bolts.

The recommended load to be used as a comparison is the
load.
The
between the maximum recommended tensile and shear load must be more than or
equal to the maximum load on each anchor taken from the loads data sheet relative to the desired
wind speed. Vice-versa, if the recommended load is less than the maximum load on the anchor,
evaluate the following options:
A) Change type of anchor
B) Suitably reinforce the wall or the floor
C) Use a loads data sheet for a lower wind speed and assign the consequent wind resistance to the
product installed.
For the correct choice and use of anchors,
* data taken from the HILTI technical sheets (ST_HY 70_2008.PDF page 259-261 and hsl-3.PDF page 62-63)
