Re: diagonal test masonry

Hi, you idealized the connection between the FRCM and masonry as intact , which is not physically correct at all over the specimen. Why do assign equalDOF interaction if the interaction is intact? Instead, you can simply merge FRCM and masonry geometries and assign them with their repsective materia...

Re: Can't visualize stresses in beam elements

Hi, you can't see the stresses on elastic section. Please use "fiber" section, which can have Gauss points at each fiber location and display the stress and strain.

Re: I kindly seek assistance from anyone knowledgeable in this subject to provide guidance and support for the presented

Hi, You have combined the different geometries (drawn separately) using "compound" command, this will only group the geometry under a single name but still the geometries are separate. So, you will face convergence issue, like singularity. To avoid this, you should use "merge" command.

Re: About ASDConcrete3D User-defined

Hi, How does ASDConcrete3D user-defined specifically consider material damage? I carefully read the introduction of the construct on the official website of opensees, but I still can't relate it to the parameters Td and Cd. You can see d+ and d- damage variables in the theory of the constitutive mod...

Re: Nonlinear dynamic analysis set up

Hi, You missed to add mass to the model. Please add them under conditions section. For dynamic analysis you need to specify mass of the model. Mass can be specified as point mass, uniform mass over edge, or volume mass. STKO offers the automated calculation of mass distribution if you specify then a...

Re: Key not in C++ Map

Hi, The error is due to not choosing the selection set for monitor, See the 2nd attachment.
Also, your model has another issue: There is an empty field in the material tags of the SFI_MVLEM element (see the 1stattachment)

Re: total displacements in the post processor

Hi, You can add the ground displacement with the relative displacement to get the total displacement. STKO postprocessor does not give you the total displacement directly, however it is pretty easy to do it in spreadsheet or STKO-Python API script. Please watch the webinar given in the link below. h...

Re: Damge TC3D Accuracy

Please check peak compressive strengths of your brick and mortar. Both are significantly larger than the prism's peak comp strength. I would say the STKO strength prediction is nearer to the strengths of these two materials - this looks fine to me. Your model shows a strong mortar and weak brick sce...
