MECHANICS
Firstly, the structural behaviour is analysed when
the wind load is applied from the top. From the
results of the table, it can be seen that with this
wind load direction, the simplification into an arch
and a rectangle is not totally effective, because
the values of bending moments, stresses and
deflection differ a lot from the real model. In this
case, the FEA seems to have more reasonable
results and therefore, be more reliable for real
situation behaviour.
The assumption of 5mm thickness from hand
calculations seems to be sufficient against breaking
load, but with big consequences in deflection.
Therefore, further FEA was needed, where the
thickness of the material was increased steadily.
In the end, a thickness of 7,5 mm was found to be
the most suitable, with a final deformation of 1,8
mm.
