Calculation ipothesys
The structure has been evaluated with the following calculation ipothesys
h = 2,30 m height at the guide bottom side
category (ground) II corresponding to"Area with low vegetation such as grass and isolated obstacles (trees, buildings) with separations of at least 20 obstacle heights"
The structural resistance of the structures with 3 and 4 modules is comparable to the one of a structure with 2 modules, with a total depth equal to the maximum depth that can be obtained by adding up the depths of 2 adjacent modules.

MAXIMUM SNOW LOAD (1 DaN = 1 Kg)the maximum snow load on the structure with folded roofing closure isqn = 70 DaN/m2 snow actiongn = 200 DaN/m3 snow specific weighthmax = 35 cm snow maximum height
FOUNDATION - PLYNTHthe plynth dimensions for the maximum action are

ANCHOR BOLT ACTION AT THE BASE OF THE COLUMNThe number of anchor bolts considered in the calculation4the maximum actions acting on a single anchor bolt are
N= 2150 DaN tractionV = 40 DaN shear
For a correct determination of the anchor type to adopte
a) identify the type of the wall/floor to which link the structure(concrete, masonry,…)b) from the producer's handbook select the anchors related to the material to which the structure is linkedc) identify the design resistance of the adopted anchor in the producer's handbook table d) confront this reduced resistance with the acting force
