Strain record

[fanseagull]

Hi everyone, I am working on modelling of progressive collapse of structures subject to earthquake, and the first problem I came across is the remove of failed elements. Say, an element will be removed when its strain reaches a specific value. However, I wonder if the strain can be captured and used in a control command after very analysis step? I know the strain can be recorded in recorder, but I don't know how to returns the data to a specific element (like nodeDisp command). I appreciate your help in advance.

yes ... use the eleResponse command .

Thank you fmk. By the way, can I obtain the maximum strain of an element among different Gauss point?

not directly .. you would have to do that in your script.
