convergence problem ASDConcrete3D

[giom]

Hello everyone!

I modelled a speciment of infill masonry wall in STKO with in which brick and mortar are homogenized in a single "Layered shell". On this model I want to do a pushover analysis using "Parallel displacement control". I used "ASDConcrete3D" for both frame and homogenized masonry.

The problem is that I have convergence problems using "ASDConcrete3D" in pushover analysis, while I had no problem before using "DamageTC3D". So horizontal analysis never gets completed.

What should I do to solve the problem? Are there any parameters to modify in order to avoid these problems of convergence?

Attached .sdc file and screeshot of analysis text and monitor.

Thank you for your help!

Probably with the DamageTC3D you were using the IMPLEX algorithm while with the ASDConcrete3D you are using the default IMplicit integration?
