StressStrain recorder in beamWithHinges Element

[amohebbi]

Hi,
I am trying to get the stress and strain in a bar in a column, and I am using Element beamWithHinges for the column. I would like to get the stress and strain in the location of the plastic hinges and the bottom of the column. I am using element recorder for that, but I am wondering in the element recorder command how/where I should define the specific length that I need to get the stress and strain. My column is 318 inches and I'd like to get the stress and strain in the bottom of the column and 18 inches from the bottom. I would be grateful if you can write an example for the recorder.

thanks

You can record stresses and strains at the integration points only. For the BWH element there are 6 integration points. The integration points for the ends of plastic hinges are 1 and 2 for Lpi and 5 and 6 for Lpj. Here is an example of the recorder:

recorder Element -file stress.out -time -ele 1 section 1 fiber 0.10 0.10 2 stress; # records stress of fiber at location (0.1, 0.1) of material 2 at section 1 (i node of the element or the 1st node of plastic hinge at node i) of element 1

I appreciate your reply.

is there really no way i can get the response, say stress strain along the plastic hinge length?
