DNV OS-C101-LRFD Weld Strength (2011)
An offshore standard DNV OS-C101-LRFD Weld Strength (2011) verifies structural stability for each structural member (weld). Weld connections (section 9) is implemented.
To add the standard execute from the main menu.
Common options are described in the Weld Strength Settings chapter.
Press 
to set a Correlation factor (Beta_w):
factor is obtained from Table C4, section 9 and depends on the material type:
- material factor that is used for DNV OS C 101 calculations can be found in Table C1, section 9 of the standard:
- material resistance factor for plated structures is a constant value (=1.15) and used in calculations to check base material strength.
Standard uses material data (Yield/Tensile) in calculations. Wizard checks if the values are defined for all materials.
Checks are created automatically and divided into few parts:
- Dimensions checks. Geometrical parameters weld area, elastic section modulus etc;
- Stress checks. Total weld throat stresses at the start and at the end of the weld. Weld Stresses are calculated using the weld dimensions at four points at the weld ends;
- Utilization factors. Total utilization factors, base material check and overall utilization factor checks.
