Methods for Calculating Screws
The Screw Calculation provides two different ways to calculate a screw
connection:
■ Stand-alone calculation: All data and properties are specified by the user.
■ Calculation of an existing screw connection: The user selects an existing
screw connection to be calculated. All geometric and standard-related data
is taken from the screw connection and cannot be edited.
In this exercise, you use the stand-alone Screw Calculation. With the
standalone calculation, you can calculate a screw connection without any
prerequisites. You can specify the screw connection in detail (material,
geometry, load, settlement and tightening properties). In this exercise, you
are provided with the drawing of a screw calculation. Some values are selected
from tables, some are entered manually, and some are taken directly from the
drawing.
To open the initial drawing
