I want to plot the base shear vs displacement of an structure using the "recorder plot " command.
The problem is I have a 3 -bays frame and the base shear is the sum of 4 reactions, so I use the "recorder Node -file reactions.out -node 1 2 3 4 -dof 1 reaction" to save the reactions in a file named "reactions.out" and "recorder Node -file displacements.out -node 13 -dof 1 disp" to save displacement in another file named "displacements.out".
Is there any way to save the displacement and the sum of the 4 reactions in 1 file and then use the plot comand? (recorder plot $fileName $windowTitle $xLoc $yLoc $xPixels $yPixels -columns $xCol0 $yCol0 <-columns $xCol1 $yCol1> ...)
thank you very much for your help!
