Appendix C - CALC SETUP
Enter the Material Modulus if it is difffernet from the selected
Material in Bolt screen. Enter the Yield value of the material.
E.g: 8.8 = 640 MPa ; 10.9 = 900 MPa B7 = 724 Mpa
(check the material constants with appenidx). NB: It is not
necessary to enter Yield value unless %- yield is to be
displayed. Choose bolt or stud pending on application.
Enter the geometric values for the bolt or stud.
See Appendix D for geometric terms.
Enter thread pitch or threads per inch.
The Engagement Factor is the percentage of the diameter at
the thread or head section that carries/sees the stress from the
structure. The default values for a steel-steel standard bolt
connection is 0,4 at the head and 0,5 for the nut. For a stud
bolt the engagement factor is 0,5 and 0,5 for both in standard
steel. Ext. See Appendix D.
This page displays results from calculation.
The results of the load factor calculation is now displayed on
the load factor entry row (make sure to store the value by
completeing the bolt type entry sequence)
