Re: Data visualization of the RC frame model

Could you be more specific?

Re: Calculate principal stress for 3D solid elements

SImply because the PDMY gives 7 components in the 3D stress (the 6 components of the stress and a 7th component related to the material itself). In this way, STKO does not recognize it as a stress vector, and it does not compute the stress invariants. Try use material.stress.6 in the elemtal results...

Re: Quasi-static loading

The question is not clear to me.
Do you want to apply a cyclic load in quasi-static conditions?

Could you make a sketch of what you want to achieve?

Re: Setting of dynamic analysis of “column dismantling method”

You forgot to assign the fixities for the dismantled column, and also forgot to add it to the first constraint pattern:

Re: New update in ASDEmbeddedElement for UP element

Ok, I had a look at your model and I think I understood why it was giving problems in stage 5: The duration of the analysis was too high (1.0e6 seconds) for the constraint on the pressure DOF using the Penalty approach. Last time I told you to use a large time value (1.0e6 seconds) for quasi-static ...

Re: Radial constraint

If the concrete is a 3D solid, should I apply the load with Faceforce or SurfaceLoad? FaceForce is the correct one. SurfaceLoad is for simulating floor loads when slabs are not modeled. In the case of FaceForce, of course, you should use "Local" and use the "Z" component of the load, which is alway...

Re: Pushover analysis of a masonry wall

There were some mistakes that I tried to fix: The Multilinear Material cannot be used in the columns where you have softening. The Multilinear material assumes stress points are increasing. Even if they seem to work in static tests... shear_1.png .. they do not work in cyclic tests ... shear_2.png ....

Re: Try to mesh cylinder into hexa not tetra

Great! However, you can improve it. The way you did it makes the elements near the corner, almost singular (their jacobian at that point is close to 0): cyl_hexa_near_singular.png A better approach is to: draw a circle with the second point at 45 deg draw an X and a Square merge everything in sub-se...
