Hi
“Is it possible in Sofistik (Teddy) to integrate beam section forces from a shell model? This could be, for example, a bridge deck modeled by shell elements where it is relevant to calculate the resulting beam forces within the structure.”
Hi Jakobgren,
Yes, it’s possible to extract the equivalent beam forces (N, Vy, Vz, My, Mz, and Mt) from a shell model using the PROG SIR module.
I recommend checking the official documentation and examples for detailed guidance. Here is an example I used in a recent project:
+PROG SIR
ECHO FORC FULL
CTRL AQUA 6
GRP NO 1 OPT FULL ETYP QUAD
LC (1000 1005 1)
LC (2000 2033 1)
LC (3000 3049 1)
LC (4000 4099 1)
SECT NO XM YM ZM NX NY NZ YMIN=-0.40 YMAX=0.40 ZMIN=-0.975 ZMAX=0.975 SX=0 SY=-1 SZ=0
1 (0.00 19.22 0.31) 0.0 0.975 -1 0 0
1 (19.5525 32.52 0.3325) 0.0 0.975 -1 0 0
1 (32.768 35 0.248) 0.0 0.975 -1 0 0
END
Let me know if you have any other questions!
Good luck!
Best regards,
