3. Special works

3.1 Tanks

These structures are subject to significant pathology due to the fact that, in the majority of cases, the concrete in vertical walls works in tension, or even compound bending.

It is imperative to limit cracking and, consequently, the tensile stress of the concrete, which must not exceed a fraction of the concrete's tensile strength, as well as that of the steels.

In the case of rectangular tanks, each plate is subjected, in the horizontal plane, to a bending moment and traction due to the thrust of the liquid on the perpendicular...
