Walls are barriers designed to resist or contain fluid pressure. This pressure may be uniform all over the surface of the wall as is the case for protection from wind and waves or it varies linearly with depth as in the case of a container.
A wall is considered to be any structural, rectangular, vertical section between its free edge and/or an edge stiffener.
Walls provides the calculation facility for a wall with 1, 2, 3 or 4 fixed edges exposed to uniform or hydrostatic loading conditions which means that you can also establish the stresses and deflections in a tank floor.
A wall or section thereof is generally rectangular resulting in stresses and deflections that vary all over its surface, even when exposed to uniform loading conditions. The wall calculator provides the maximum of these values along with their location.
Walls determines the maximum stresses, deflections and/or reactions in a wall required to resist wind, waves or hydrostatic forces.
Walls also provides the minimum second moment of area for the edge stiffeners of the wall or tank panels required to maintain your specified deflection rate (deflection per unit length).

Walls Calculator  Options
The walls calculator has the following calculation options:
1 SIDE FIXED
A fixed foundation (or base) with both vertical edges and the upper rim free to move without constraint
2 SIDE FIXED
A fixed foundation (or base) with one vertical edge fixed from all movement and one vertical edge and the upper rim free to move without constraint
3 SIDE FIXED
A fixed foundation (or base) with both vertical edges fixed from all movement and the upper rim free to move without constraint
4 SIDE FIXED
A fixed foundation (or base) with both vertical edges and the upper rim fixed from all movement
