Element eccentricity

Post by giorgioirotina » Fri May 16, 2014 9:56 am

In my understanding users can define fiber sections with any local coordinate system, opensees will always calculate the centroid of the fiber section and make it coincident with the reference line of the frame element.
This way it's impossible to give centroid eccentricity just displacing all the fibers of a certain amount equal to the eccentricity.
I'm using force beam column elements and offset is not implemented for corotational geometrical transformation.

Is there an easy way or any workaround to do it without adding more nodes to my model or rigid elements?

no easy workaround .. people playing with this for example to model beam-slab usually move the nodes at cols at centroid of section as opposed to centroid of steel beam.
