Hi everybody, I still don´t get any response to this request, I believe that the answers do not come on this forum soon, I hope to receive a reply from you soon...I´m ten days waiting a response. Thanks.
regards.
In the detailed results of a segmented Member, SACS indicates that the overall buckling length for segmented members is recalculated according to the buckling load of that segment. Can anyone show me a solved manually example, showing the way in which SACS recalculates the overall buckling length in segmented members (K * L)? I mean the value indicated below:
****** Member's Properties ******
Slenderness Ratio (KL/r)y 178.63
Slenderness Ratio (KL/r)z 178.63
Radius of Gyration ry 41.78
Radius of Gyration rz 41.78
Eff. Length Factor Ky 2.10
Eff. Length Factor Kz 2.10
Overall Buck. Length Ly 37.95 (m.)
Overall Buck. Length Lz 37.95 (m.)
Final (K*L)y 79.70 (m.)
Final (K*L)z 79.70 (m.)
- Segmented Member: Overall buckling length is re-calculated from apprximate buckling load effectively at this segment.Leffy 35.54 (m.) Leffz 35.54 (m.)
TUB Ring Spacing 37.95 (m.)
Reduction Factor Cmy 0.85
Reduction Factor Cmz 0.85
Lecoroni,
SACS is using the below formula for the segmented members, you can see this in the manual 5.1.13 Member Group Summary.
The formula is kl/r=(12*PI^2*E*A/23Pb)^0.5
Once you get this number multiply by r value and devide it by K value, you should get 35.54m
