Shear forces in small excentricities

[agps]

Dear colleagues,

I have an excentricity between 2 columns of 190mm distance from their gravity centre. At the point of excentricity I´ve a beam 0,3x0,6

Performing an hand calculation on the beam, I usually increase the shear value at a 3.d distance from the support, dividing the shear value by the reduce shear value and multiply by its 'fv'.

My question is, in FEA should I keep doing the same or should I accept directly the shear values from my model without any further increase in a 3.d distance from the support?

Thank you

the "3d" term accounts for how the structure reacts to the applied shear. i'd say that the FEM accounts for this (by doing a way more sophisticated calc than you'd ever do by hand)

rb1957,

Thank you for your answer.

But I still wonder, if I apply the same geometric conditions on a simple case of supported beam and with the same excentricity, I´ll get the same shear values as the FEM.

Let´s say that the value for that load is 450kN. The diagram is simple to get and is exactly the same as the FEM.

Do you still think that I should accept directly the shear values?

Thank you,
