Shear force and torsion at angle beam

Shear force and torsion at angle beam

Shear force and torsion at angle beam

(OP)
In a welded truss system with angle beam element, beam local forces are required for next step analysis. These values are from s7 to s12 in output file "study/analysis/study.s##". The results for shear force and torsion are about 50 to 500 times of expect values. This problem does not exist in models with circle beam.

Adjusting the offset in the beam orientation did not solve the problem.  

What cause this problem and how could I fix it? Thanks in advance.
