SectionAggregator Object

If you have a script you think might be useful to others post it
here. Hopefully we will be able to get the most useful of these incorporated in the manuals.

SectionAggregator Object

Post by ftong » Wed Mar 06, 2013 12:10 pm

Dear Colleagues,

Here is a question about SectionAggregator object.
I am trying to incorporate linear elastic shear component into an already-defined fiber section that captures the axial and flexural behaviors. To my knowledge, the following scripts are to be used:

section Fiber $fiberSecTag { ; # this is already defined
uniaxialMaterial Elastic $matTagV $tangent;
section Aggregator $aggrSecTag $matTagV Vy -section $fiberSecTag

Should "$tangent" in the uniaxialMaterial definition be the shear modulus G or GAv where Av is effective area of the fiber section?

GA and remember it only works in the force beam column element (not the displacement element)
