Beam Moment and Shear Problem

[Sambrook]

Hi,

The Beam is displaying what appear to be incorrect moment and shear results.

The beam is continuous and has one way RC slabs spanning onto it on both sides. The beam is considered as fixed at both ends and has a torsional release. I have pinned both ends and the moment is just as extreme and jagged.

The connection at the end of the beam consists of 4 beams spanning into a column. The beams are not offset and meet the column at it's end node.

The Beam does not have any beams spanning onto it throughout it's length.

If you could shed some light on what could be going wrong it would be much appreciated.

I have also include the bending moment of an adjacent beam with similar loading.

Cheers

Richard

Remarks
- you can not neglect instabilities type 1 and 2 in model - results are, may be not correct
- you can not release the same dof on bars (500 501 in your model) on side of supports with the same dof released
- do not EVER use kinematic kinks
- do not use regular mesh

My model: http://we.tl/ORV9wEYhCe
- correctly meshed
- releases on bars 500 501 deleted
- ignore remaining instability (if you switch to skline solver instability type 3 - can be neglected ; on robot 2014 turn off DSC - no instability)
