performance function

Post by negin »

Hi

How can we use one element internal forces (for example moments) in the performance function of a reliability analysis?

Thank you

Hi Negin,

You could use the recorder directly in the performance function.

for example, {rec_element_1_localForce_3}
uses the recorded local element force of element number 1 in the direction 3 (which I think corresponds to moment). The response at the last step of the analysis is used in performance function evaluation.

You could use the regular "recorder" command to have the results from the finite-element analysis, and then have a variable to read the required information from the file.

Hope this helps,
Smitha
