Re: Joint modeling

I would suggest you to start 1 step at a time.
Watch our webinar on the automation we have for RC beam-column joints.
Once you have it, you can use the lumped plasticity approach to include the slip section

Re: STKO with Windows 11 on ARM / Snapdragon X

it should work but through an emulator performance might not be the best

Re: Combined Gravity and Time-History Analysis

Are you sure you sent the real model?
this one doesn't run, all G are zero!

Re: mpco recorder was not created

That error message means that OpenSees crashed.
if it crashed soon before starting the analysis, it makes sense: no MPCO to write to.
Otherwise, the only reason for not writing an MPCO files would be that maybe you defined the recorder after the analysis

Re: OpenSees -3 error flag

Then maybe it's a problem of brittleness of the response: the Force beam column localizes in only 1 gauss point. it's more accurate but might give more convergence issues

Re: Combined Gravity and Time-History Analysis

Dear user:

Differences in the TH results are plausible because in the combined test, the TH follows the gravity and might be affected by it
Differences in the Gravity is not plausible: they both start from a "virgin" state. So there might be some differences in the settings. But without any ...

Re: Concrete Breakout Cone properties

Dear user,

I am planning to use ASDConcrete3D solid elements, but was wondering if that is the best material to use for shear dominated (or diagonal tension) failure mode?
The ASDConcrete3D is a full 3D plastic/damage material so it should be able to model it properly.

Also, for solid blocks ...

Re: How to extract physical (non-regularized) material strains from ASDConcrete1D / ASDSteel1D for code compliance?

Dear user,

This can be done by requesting, in the **MPCORecorder**, a custom elemental result such as:

material.crackStrain.-lchRef.XXX
for the tensile criterion,

or

material.crushStrain.-lchRef.YYY
for the compressive criterion.

Here, **XXX** is your reference length.

IMPORTANT NOTE ...
