Various design variants are possible for rectangular tanks:
Calculation of cover
Unreinforced tanks excepted, tanks can be dimensioned with or without a cover.
List of steel profiles
For reinforced tanks the user of the program can choose from an extensive list of U-, I-, L-, IPE-, IPB- and hollow profiles. The list always shows just those steel profiles which meet the static requirements for the tank to be calculated.
Inclusion of tie rods
For all-round-reinforced and yoke-reinforced tanks tie rods can be included in the calculation.
Easy optimisation of tank designs
Calculation for tanks with all-round reinforce- ment is done optionally either "PC-optimised" or "Interactive". In case PC-optimised is chosen, the bottom panel of the tank is calculated and the required profile transferred to the panels above it. If calculation is done interactively, each profile can, if statically possible, be reduced in size.
Moreover, the height of each profile can be modified. Here the software checks interactively whether the determined wall thick- ness is adequate and, if necessary, increases or reduces it automatically.
For edge reinforcement a plastic profile can be selected instead of steel. Here the next higher sheet dimension is specified for the thickness of the plastic profile than for the side wall.
