AnswerDifferences resulting from the determination of the deformation in the cracked state can have different causes. The following points should be checked for deviations:
Is the same calculation method applied?
RF-CONCRETE Deflect uses an analytical analysis approach according to EN 1992-1-1 7.4.3.RF-CONCRETE NL uses a physically nonlinear analysis approach.More detailed information about the calculation methods can be found, for example, in the RF-CONCRETE Surfaces Guide in Chapter 2.7 and 2.8.
Is the same initial structure available?
The results of the linear calculation provide the best tool for consideration if the underlying system should be taken for equivalent. The linearly determined deformation of the underlying combination should be approximately equal. Any possible differences in the linear deformation may be increased in the cracked state in connection with the deformation analysis.
Are the same effects taken into account?
When performing a comparison, make sure that the same effects as for example creep and shrinkage are taken into account (Figure 02).
Are the same input values available?
Furthermore, it should be checked in connection with the deformation analysis if the same input values are available. In this case, it is necessary to pay particular attention to whether the applied reinforcement (Figure 03) and the lever arm or concrete cover are the same.
If not having found the cause after the fundamental examination, please contact our hot line.
AnswerFirst information beforehand: If the program was started as a full version, it does not jump into the demo mode if the license cannot be found during the calculation or saving process.It remains in waiting stage until the license is available again.It is then necessary to distinguish the type of licensing.
For the single-user license, it should be checked if the hardlock was installed on the computer and if the indicator light situated at the end of the dongle is visible. If not, another USB port - preferably directly on the PC - should be used.In case of a network license, the problem might be caused by a failure in the network connection. In the web-based license user interface http://localhost:1947/_int_/devices.html, it should be checked if the license key is available there.Additionally, it is possible to look at the http://localhost:1947/_int_/features.html to see if a free license is available for the desired program or add-on module.If the licensing problem persists, you can create a diagnostic report from the warning message. Send it to our client support.
- Single-user license
- Network license
AnswerThe capacity of your C drive: no longer allows installation of the program. You must choose another partition of your hard drive for installation. You can proceed as described below:
- Start by displaying the "Run" command from the Start menu by clicking Start Menu> Run (or the Windows + R key)
- Type regedit and confirm
- Open the key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion
- On the right, double click on the key: ProgramFilesDir and modify the data of this key by the new path of the installation folder.
- For example, enter the path D: \ Program Files to change the partition on which the installation will take place.
- Finally, you restart the installation with a double-click on the icon.
AnswerThere is no program file size limit if you are using a 64-bit system and the 64-bit version of RSTAB 8 or RFEM 5.The 'Limit' is determined by the computer configuration.It may happen that the available random access memory plus the virtual memory defined in Windows (free memory space) is insufficient. In this case, the computer configuration can be optimized (more random access memory, more free hard disk capacity).
AnswerIt is difficult to enumerate one or particular reasons for the deviations. Basically, the design in RF-CONCRETE Columns is an analytical method, the nominal curvature method according to EN 1992-1-1 5.8.8. One advantage here is that it is a standardized method and that all intermediate values of the calculation are output in the add-on module.By means of the intermediate values, it is possible to search for the cause of a deviation between different design programs.If you cannot find the cause, please contact our hotline. In this context, however, we need a printout including the input and intermediate values from the program used for the comparison.
An individual demonstration is usually possible with a lead time of one to a maximum of two weeks. Please send us three suggested dates. The respective employee will contact you.
The demonstration itself runs via the program TeamViewer or GoToMeeting. You will receive a link to download the corresponding program in advance.
It should take about one hour to calculate the time required for the demonstration.
It is possible to switch off displaying of the warning messages before the calculation by using the "Display Warning Messages before Calculation" check box in the program options (Figure 1).
You can open your own programs in the menu "Add-on Modules> "Add-on modules".
To do this, open the file "C: \ Program Files \ Dlubal \ RFEM 5.XX \ RFEM.ini" with a text editor. The text editor must run with administrator rights.
The following three lines show how the Windows text editor Notepad can be inserted in the menu as an example:
ModuleName2 = Notepad
ModuleExeName2 = C: \ WINDOWS \ System32 \ notepad.exe
ModuleDescription2 = Editor
