ation routines, we present here the example of an unbonded
partially prestressed simply supported beam, as shown in the
diagram of Figure 26. This structure was used in the extension
of Estação Shopping Mall, in Curitiba, state of Paraná, Brazil.
The beam, locally cast, has a span length of 12.92 m and sup-
ports permanent (g = 10 kN/m, not considering its own weight)
and variable (q = 23 kN/m) loadings distributed along its length.
Moments M
1
= 468 kN.m and M
2
= 526 kN.m were considered
in each beam end. These moments, which take into account
