Dear all,
I'm creating the model attached. On each floor, I want to add 4 EqualDOF + ZeroLength elements. The floors are artificially separated to allow for the insertion of the EqualDOF + ZeroLength elements. However, when I click on "write input file", the following lines are included multiple ...

Hello everyone, I just tried version 3.7 of OpenSees to create a simple single-degree-of-freedom model, where I added a stiffness-based damping model and applied a pulse-type load. It seems the Rayleigh function isn’t correctly incorporating the value of beta_K, as the displacement history does not ...

Thank you very much! Good hack. Although it is not very good for large models because you need the fullGenLapack solver, slowing the process.

Hi,
I'm trying to obtain in a concentrated plasticity model the damping forces aiming at obtaining the damping energy by integration of damping forces and nodal displacements. I've used the model for damping "modalDamping" and the recorders "rayleighForces" and "rayleighForces!". With the first ...

I attach the model

Hello everybody,

Reproducing an out-of-plane bending test of a slab by simulation, I came across a malfunction in the hysteretic behavior of PlaneStressUserMaterial because concrete increases its tensile much more than its threshold, reproducing an unreal situation (tensile strength larger than 1.5 ...

Dear STKO Team,
It would be worth creating a new button in each category as customCommand, it would give more flexibility in complex models. Specially, for those that we have used OpenSees for a long time.

Thank you in advance,

Hi!
I'm using STKO v2.0 and when I create a ZeroLength Element with an elastic material assigned to ZeroLength material with the 6 dof activated, dof 6 doesn't appear activated. The same result is obtained activating dir1, dir2, dir3, dir4, dir5 and dir6 than activating dir1, dir2, dir3, dir4, dir5 ...

Hello,
My problem is related with the file .mpco generated when I run a model (.scd) in version 1.1, which is a model created from version 1.0. In such case, an error pops up like this:

Cannot open output database "C:/Users/galei/Desktop/Escalera basculante/Cálculo/REC2.mpco"
Error: cannot open "C ...
