The example files (PR1.tcl, procMKPC.tcl, procUniaxialPinching.tcl, procRC.tcl) create a model of a RC beam column sub-assemblage. The cruciform is subjected to constant gravity load at nodes 4 and 7 and pseudo-static cyclic lateral load under displacement control at node 10. The beam-column-joint region (element number 7) is represented using a beamColumnJoint element, and the beams and columns (element numbers 1 through 6) are modeled using the nonlinearBeamColumn element. The beam-column joint consists of 13 components that may have different material constitutive models; in this example 9 of the 13 components utilize the nonlinear material model – Pinching4.

The displacement history for node 10 is as shown below.



The p-delta response of cruciform, along with the response of each of the nonlinear joint components is shown below.



The shear panel response shows the moment-curvature relationships whereas the bar slips at the beam top and bottom are represented by the force-slip plots
