SHELL/3D versus SHELL/3D-SI

Hy community,

My test model (see attached picture) with linear elements (3D/DKT) produces a deformation of 1.77 mm. 
There is no difference between 3D and 3D-SI.  The same calculation with Abaqus gives a displacement of 1.79 mm with C3D8/S4 elements. If I replace C3D8 with C3D8R (reduced integration), I obtain a displacement of 2.64 mm.

I expect a result around 2.5 mm ( beam, analytically FL³/3EI). I also obtain this with a pure shell model.
Have I missed something (3D versus 3D-SI)?

Best Regards,

Hansbau52
