2 Starting a Calculation
After the export from Modeler to Analyzer a lot of relevant definitions such as node coordinates, element, material and cross section assignment are already available.
Before defining further input data a check of the current situation is suggested. Use the cal-
culation-function to start a cross-section calculation and structure check. The calculation
can check the stability of the system and obtain the relevant cross-section parameters (area,
eccentric and moment of inertia).

2.2 First Results
The view of the structural system on the screen can be changed using either the buttons at
the left vertical menu line or using the freehand symbols (rotate, zooming in, zooming
out,.).

3.1 Import of Material
All materials that are defined in Modeler will be imported from the standard material da-tabase to the project directory during an export from Modeler to Analyzer. Due to the fact that the tendon definition has to be added in Analyzer the material used for the ten-dons has to be imported from the available material database manually.

Once the tendon geometry is defined for all 3 tendon groups the stressing sequence will
follow (initial stressing, wedge slip,.).
All actions on the tendons are done in this table, please consider the right order!
Define the following actions:
1. Stress tendon group 101 with factor 1.06 (6% short term overstress) at one (left) end.
2. Losses due to wedge slip at the same (left) end of 6 mm.
3. Stress the tendon group 101 at the right end again with a factor of 1.06.

Each load is defined in an individual loading case.
An automatic accumulation of all loading case results is available using the Load man-ager facilities.
The loading results can be combined to create needed load combinations.
These created combinations can be combined with other combinations to create total envelopes.
Multiplication (safety) factors can be assigned to any result combination easily using a combination table.

11.1 Project Export
All data (cross sections, material, system, schedules,.) can written into an ASCII file with
a special (and very powerful) format. RM uses TCL, a special script programming language to work on existing ASCII files.
Export
Select File and Ex-
port TCL Project Data
to create the ASCII file.

Define a new file name
which will contain all
data after the export.
Additional selections
can be ticked as you
can see at the left (to
export certain parts of
the data only).
After confirmation the
ASCII file can be
opened using the editor
button in the main
menu. View it, and if
something is modified,
re-import it into RM (Recalc must be run
then to update the re-
sults).
