User-friendly user interface
The user interface of the tank calculation program was designed along the lines of
the well-known Microsoft office applications, thus enabling even beginners to familiarise themselves quickly with the use of the program.
Help texts on the user interface
To further simplify use of the program, in this version help texts in the form of info-boxes were integrated into the user interface.
More than 200 queries enable user input with regard to plausibility and feasibility to be checked, so ensuring that tanks can be both optimally and safely designed.
The new, powerful Sql data base enables the same tanks to be worked on from different work stations.
For the first time simultaneous calculation
of more than one tank is possible in RITA. This enables direct comparison of the results of calculations and so facilitates the optimi- sation of tank designs.
Both user interface and complete printouts of structural engineering calculations can be in German, English, French and Czech.
Documentation of calculation results
RITA offers as an alternative to the printout of a complete static calculation report, which contains data required for the approval of the tank, a means of preparing an abridged version in the form of a data sheet. At the same time the data on customers and buil- ding clients also are automatically trans- ferred from the program to the printout.
The calculation bases for the program are based on the internationally recognised DVS Guideline 2205. The program also offers a means of designing tanks beyond the scope of the DVS 2205 Guideline. The program signals whenever the scope of the guideline is departed from.
All material characteristic values, such as creep rupture strength, creep moduli and joint factors as well as reduction coefficients for toughness and the effects of chemicals, are filed in the RITA data base.
Choice of materials
Alongside PE and PP, also PVC-U and PVDF can be chosen as tank materials.
In September 2011 the DIBt’s (Deutsches Institut für Bautechnik – German Institute for Building Technology) new Media List has been released. All important amendments have already been incorporated into the current RITA program. As well as the DIBt Media List RITA offers a means of preparing one’s own media list. The media are stored in the data base and can be used for every new tank calculation.
When designing round tanks, as well as the short-time and continuous media temperature, the mean and maximum ambient temperature can also be specified.
