Re: DamageTC3D

A concrete has always a tensile strength. It soon tends to zero due to cracking. But it is never exactly zero from the beginning. This is an assumption that is often done with reinforced concrete in beam sections. Anyway, if you want to simulate it, just use a small ft value, but it will affect the ...

Re: Nothing to regenerate

I'm sorry but the problem with this file is different. It says it is corrupted and cannot be opened.
Do you know when the crash happened?
Can you reproduce it on another file so that I can debug it?

Re: MOMENTS AND SHEARS IN SHEAR WALL

Regarding the difference in the modal properties There can be many reasons for 2 different software not to match. Especially in the nonlinear range. Note that you are doing an eigenvalue analysis after a gravity analysis with nonlinear materials. Are you sure in ETABS you do the same? Are you sure ...

Re: Soil Structure Interface Modeling

I am working on adding more elements to the model and columns and slabs are next. I am running again with issues with meshing: 1) After adding columns I need to divide soil geometry so my soil and structure mesh are compatible (for contact modeling) and what I did is the following: 1) Draw lines on...

Re: Multi-support excitation in soil model

I think that the periodic conditions are fine for a centrifuge test. Try to google and search for similar issues. For example: "boundary effects in centrifuge tests"

Re: Unable to Visualize Stresses in Elastic Membrane Sections

It's because the ElasticMembranePlateSection, assuming an elastic behavior, works directly with analytically integrated section forces, it does not perform numerical integration of stresses using fibers. For example, given the equation for the membrane force in the X direction: F_xx = integrate(Sigm...
