Dear All,

I have some questions regarding the use of the joint element formulation and the calibration procedures. Firstly, regarding the calibration procedure for the bond slip response, from where should  I get the bar stress (fs) that will be used to get the bar stress vs. bar slip and spring force vs. bar stress relationships?. Secondly, how are the  Bar Slip Spring Resultants (i.e. f1 f2 f3 f4 f5 f6 f7 f8 f9 f10 f11 f12 f13) related to the previously mentioned relations?. Thirdly, what are the procedures that I should follow to obtain the Joint Shear Response from the diagonal compression strut mechanism?

Thank you very much in advance for you kind help.
