Round tanks

Design variants

RITA® offers a means of dimensioning tanks in conformity to the supplementary sheets to DVS Guideline 2205 with a conical and sloping bottom. At the same time the skirt and supporting structure for the bottom are calculated.

Openings in the cylinder

When dimensioning tanks with nozzles in the cylinder, RITA® allows calculation of the thickness of the cylinder wall taking into account the supporting effect of the pipe wall thickness according to DVS 2205-2. In RITA®, either the corresponding SDR class or the pipe wall thickness can be chosen freely. At the same time the user is given information about the permissible area in the cylinder where the opening may be located.

Roof structures and roof loads

The RITA® program distinguishes between roof structures which apply a load to the cylinder only and roof loads which act on the roof. Roof loads are entered as surface loads; for roof structures which are specified in N the program enables the number and width of the load application points to be specified and also takes into consideration traffic loads which may act for a short time on the cylinder edge during installation of roof structures. It is also possible to consider scaffolding in the calculation.

Physical accessibility of flat roofs

When calculating a tank with a flat roof, the option is offered of making the roof physically accessible or not.

Tanks in shell construction

In special cases, if bending of the sheets is no longer possible because of the required wall thickness, tanks must be manufactured double-walled. As a result, RITA® indicates the minimum thickness of the inner shell and minimum height of the reinforcement shell.

Manual adaptation of wall thicknesses

On the results page the minimumrequired wall thicknesses for the cylinder, bottom and roof are specified. These can be manually adapted and so optimised.

Wind and snow loads

Via the new wind and snow load tools, wind and snow loads can be conveniently defined by selecting the respective zone or interactively by selecting in the map.

Earthquake protection

Where tanks are to be installed in areas of seismic activity, verification of earthquake protection is increasingly being required for them. Now RITA® offers a means of designing and anchoring cylindrical, flat-bottomed tanks so as to make them earthquake-resistant.

Uplift protection

Under DVS 2205 verification is required that for the event of damage 0.9 times the weight of the tank is greater than the uplift of the immersed tank component. If it is not, RITA® emits a warning and enables e.g. the collecting diameter to be adjusted.
