Re: MP model can not convergy

You should try your analysis with a different steel model. ReinforcingSteel is known to have some issues. Thank you very much for your answer, you are so kind! ! However, I can only use this model due to the need to consider the descending section of the reinforcement. I want to know what is the ge...

MP model can not convergy

Hello everyone, I would like to ask a question about convergence. I used the ReinforcingSteel model to build a bridge pier model, and the following error occurred. What do these errors mean? Looking forward to your answer! WARNING: ReinforcingSteel::SetMP() - did not converge finding da and ao Uniax...

Re: Deformation components

I tried the model that only considered bending, but extracted the curvature of the pier bottom section to calculate the bending displacement. This value is also not equal to the displacement of the pier top node. Why is this?

Deformation components

Hi everyone!I have a problem. Could you please take a look In order to find the component part of deformation caused by bending and longitudinal bar slip, I establish a cantilever column ( dispDeamColumn+zeroLengthSection ), but found that the two displacements add up to less than the total displace...

The common usage of this is for horizontal displacements to obtain the drift ratio as the displacement divided by the length of the element. It is not so meaningful for rotations.
Thank you for answering my questions, I can get your enthusiastic answer is my luck!

Re: questions about example SS_IC1.TCL

If the moments are similar, curvatures should also be like that. If there is a factor of 12, it looks like there is an issue with units. Curvature units should be in 1/length unit, you are right. You can also double check everything to see if it satisfies M/EI=curvature in the elastic range. Thanks...

Re: Zerolength drift

This is a recorder to obtain the drift (displacement normalized by length of the member) between nodes 1 and 2 for DOF 3. You can find explanations of the parameters used in this recorder here: https://opensees.berkeley.edu/wiki/index.php/Drift_Recorder Thank you for your reply and information. I h...

No these are not related to curvature.
Thank you for your answer! May I ask what does this mean?

recorder Drift -file drift1.out -iNode 1 -jNode 2 -dof 3 -perpDirn 1"

Looking forward to your recovery. Thanks again

Yes that gives you the stress and strain, for the curvature you should use recorder Element -file Element1.out -time -ele 1 section deformation for the moment, it should be recorder Element -file Element1.out -time -ele 1 section force Thank you for your answer!Dear selimgunay!

Re: Zerolength drift

The code for one case is "recorder Drift -file drift1.out -iNode 1 -jNode 2 -dof 3 -perpDirn 1" , "recorder Drift -file drift2.out -iNode 13 -jNode 2 -dof 3 -perpDirn 1", and the zerolength element is consist of node 1 and node 13. Do the above two codes mean curvature? The curvature of the zero-len...

Re: questions about example SS_IC1.TCL

You can not get the curvature at a section by using the Node recorder. You should use the element recorder. Please see the example at the bottom of the page at the below link. https://opensees.berkeley.edu/wiki/index.php/Element_Recorder thanks for your replying, selimgunay! :D I looked at the comm...
