The structure is a 3-span continious beam.
The dat is attached:
3-span.dat (2.0 KB)

I define a unit vertical load on it,

LC NO TYPE
100 L
TRAI TYPE
USER
TRPL P

I want to get envelope diagram of 3 internal forces under this unit traffic load

CALC TYPE LMAX LMIN
MY 10 11
VZ 20 21
MT 30 31

How to envelope diagram of 3 internal forces?

You already have it.
Open wingraf and check the results for beam elements and the loadcases 10,11,20,21
MT doesn’t exist since none of your loads generate a twist.

Thank you for the tip. I can find the diagrams in the wingraf.
I also want to see the envelope in the report broswer, below is the code:

PROG WING
LC NO
10
BEAM TYPE
MY
LC NO
11
BEAM TYPE
MY
END

But it shows warning:

+++++ warning no. 806 in program gr3_e_stab
BEAM TYPE MY loadcase 10 not valid : No values found
BEAM TYPE MY loadcase 11 not valid : No values found
