The load combinations 5A and 5B give the maximum value
of the compressive stresses in the masonry.
The main differences between the analysis 5A and the
analysis 5B are summarised in the following:
 the value of the maximum compressive stress at the crown of the arch
is equal to 23.78 kg / cm^{2} in the analysis 5A and
increases up to –27.79 kg/cm^{2} in the load combination 5B
(with a percentage variation of + 17 %), where the maximum values of
the elasticity modulus have been assumed for the whole structure
 in the spandrels the stresses increase from the value of –15.42 kg
/ cm^{2} in the analysis 5A to the value of –18.85 kg / cm^{2}
(with a percentage variation of + 22 %).
