Shear forces in small excentricities
Shear forces in small excentricities
(OP)
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

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,
