Regarding on this topic, I want to clarify that my structure is modelled with the macromodeling approach (bricks and mortar as a homogeneuos material). So, I want to ask you: do I need to reduce the transversal shear stress with respect of the in-plane shear stress (by means of using ortrothopic ...

But in a dynamic analysis like the one I am performing, do i need to add mass density + vertical loads? or with mass density is enough?

Oh, I thought that adding a mass density in the ASDConcrete3D materiales would be enough. Always I need to add the FaceForce aswell?

Hi,

I would like to know whether the model attached to this message (confined masonry walls modeled using a macromodeling approach) is suitable for tsunami loads in a dynamic analysis, specifically regarding out-of-plane behavior. In particular, I have some doubts related to the following points ...

Hi again!

Before your response, I want to make an update below: I have been trying a lot of changes in the model like the use of EnergyIncr as convergency criteria, adding viscosity in the ASDConcrete3D materials, using the TRBDF2 integrator instead Newmark 0.5 0.25, among others. With this changes ...

Hi STKO Team!

I want to ask about a convergency issue that I am dealing in a confined masonry structure subjected to acceleration recording in the X and Y directions. In the document CM Building that I attach you can find this STKO model with the planes of the structure which were the used ...

Dear STKO,

As part of my master's thesis, I would like to make a sensibility analysis about the analysis setup in a shear wall model. The main attributes that I want to evaluate are the testCommand and tolerance. The modifications that I would like to make are the following ones:

- testCommand ...

Ok, I will prove that if this solves the issue.

For my model, what could be a good number for the alphaS and alphaM parameters for Penalty Method? I read in other responses in the forum that alphaS = alphaM = 10^(8 + oom), with oom = round(log10(K)). My model uses shell elements with a 50x50 mm ...

I will reply the questions:


This is strange, to speedup debugging this issue, could you tell me 1) what did you change between the 2 runs that gave different results? and 2) what result did you check? so I will focus on that


1) There is no difference between the models, I just run the model a ...

Hi!

I want to ask if it is possible to combine two test commands in STKO, as in OpenSees or other softwares? For example, is it possible to use RelativeNormIncrTest + RelativeEnergyIncrTest?

Also, what are the recommendations about the best test commands to use in a non-linear static and dynamic ...
