P-Y Curves

[billu]

Hi everyone..I hope you all will be fine.
I am studying example on opensees website "Laterally Loaded Pile Foundation".
I am stuck in generating p-y curves from output of opensees..Can anyone guide me that how can i extract p-y curves from opensees?? I am pasting the link of the example problem.

In this example (API sand) is coded in the program.I know my questions are quite basic.But i am new to opensees..Please answer about this issue.Thanks in advance.

Take a look at your recorders:

Around line 220 in staticBNWFpile.tcl you will see the following lines:
# record displacements at pile nodes
recorder Node -file pileDisp.out -time -nodeRange 201 [expr 200+$nNodePile] -dof 1 2 3 -dT $timeStep disp
# record reaction force in the p-y springs
recorder Node -file reaction.out -time -nodeRange 1 $nNodePile -dof 1 -dT $timeStep reaction
# record element forces in pile elements
recorder Element -file pileForce.out -time -eleRange 201 [expr 200+$nElePile] -dT $timeStep globalForce

So OpenSees is outputting node displacements to a file called pileDisp.out and the forces in the pile elements to a file called pileForce.out. Take a look here to figure out which column applies to which DOF etc. http://opensees.berkeley.edu/wiki/index ... e_Recorder and http://opensees.berkeley.edu/wiki/index ... t_Recorder

You ought to be able to construct your graphs from these files.
