How to record hinge?

I want to know the process of hinge development , so , how can I record hinge ?
The element I used is beam With Hinges!

Is this right?
recorder Element -file $dataDir/PlasticDeform.out -time -ele 1 plasticDeformation;

the deformation just means the hinge rotation?

However, the output I got is six teams of data! What may the reason be? what are the surplus three teams? Part of data...

Thank you so much. I solved my problem.

[quote="vesna"]I looked at your file, made few changes and now it works fine. There were two reasons for your code not running properly: 1. The plastic hinge lengths of all elements were extremely small (at least 10 times smaller then any reasonable value of a plastic hinge) 2. The displacement incr...

[quote="vesna"]This message means that the element 111 has probably failed at the load factor of 253.29. Look at the pushover curve to see how far did your structure go. If your structure is in the elastic range when the element 111 fails, your model requires modifications. If your structure experie...

Can beamwithhinges be used in column?

when i make column used element beamwithhinges, the result is unrealistic, therefore, I wonder, whether the element beamwithhinges is not considered used in column? Besides, if I take no consideration of gravity load, the result I got is reasonable. So, when the element beamwithhinges was usd, there...
