there is nothing in the code now that will send you a notification that a strain has been reached. you will have to put it in the script.

because of not workin of that, ive forced to write a tcl program that in each step of cyclic analysis,give me the maximum strain range for the entire time history, where the maximum strain range is the summation of the absolute values of the maximum tensile and the maximum compressive strains. (for example midspan of brace in outer fiber of hss which always occur @ the extreme fiber on COMPRESSION side of plastic hinge.i dont know how

it works on some but not others because it was compiled for a different version of OpenSees. if you get a copy of the correct version for which it was compiled t will work.

Dear jackmil
I want to use Hsiao's FractureMaterial model, how can I build the .dll file of the .cpp & .h of that material?
Please help me.
I really appreciate if it is possible for you to send your .dll file to me?
My email address diamond.desert71@gmail.com
and How can I use the .dll file?
Best regards.
