Dear Sir,
I'm running a spectral fatigue analysis for a platform with grouted legs. These are my section input for my joint cans at leg
SECT LEGCAN TUB 111.765.08091.4403.810
SECT LEGCAN1 TUB 111.765.50091.4403.810
SECT LEGCAN2 TUB 111.766.00091.4403.810
Below are my input in fatigue input file that I use ISO 19902 for the effective thickness calculation for grout.
FTOPT 7 1.0 1.0 SMIJ2 SK MNSK K LPEFT
FTOPT2 PTPTVC PV AP 2.0 -3.0 5.5 -69.70069.7000 31.75
*
SCFLM 1.5
However, after I ran the analysis and check the fatigue output listing file, the results shows that it consider the thickness of outer member which are 5.08mm, 5.5cm and 6.0cm only.
From my calculation of Te = (T^2 + Tp^2)^0.5 in formula 14.5-1, it should be 6.35cm, 6.69cm and 7.107cm.
Please help to let me know it there any input I missed for grouted joint, or there is other consideration that not allow me to consider effective thickness of grout. I can share my input file for further discussion if it's required.
Thanks,
Best Regards,
Pei Shing
