uniaxialmaterial hysteretic error

[Prafullamalla]

when I use uniaxialmaterial hysteretic materail.it displays want uniaxialmaterial hysteretic tag? moment1p? rot1p ? bla bla . What does this mean.how to solve this

Why don't you send us your code for defining the material?

Actually, I copied it from one of the example. Here, it is.


# reinforcing steel
set Fy [expr 60.*$ksi]; # STEEL yield stress
set Es [expr 30000.*$ksi]; # modulus of steel
set epsY [expr $Fy/$Es]; # steel yield strain
set Fy1 [expr 95.*$ksi]; # steel stress post-yield
set epsY1 0.03; # steel strain post-yield
set Fu [expr 112.*$ksi]; # ultimate stress of steel
set epsU 0.08; # ultimate strain of steel
set Bs [expr ($Fu-$Fy)/($epsU-$epsY)/$Es]; # post-yield stiffness ratio of steel
set Bs [expr ($Fy1-$Fy)/($epsY1-$epsY)/$Es]; # post-yield stiffness ratio of steel
set pinchX 1.0; # pinching parameter for hysteretic model
set pinchY 1.0; # pinching parameter for hysteretic model
set damage1 0.0; # damage parameter for hysteretic model
set damage2 0.0; # damage parameter for hysteretic model
set betaMUsteel 0.0; # degraded unloading stiffness for hysteretic material based on MU^(-beta)
uniaxialMaterial Hysteretic $IDreinf $Fy $epsY $Fy1 $epsY1 $Fu $epsU -$Fy -$epsY -$Fy1 -$epsY1 -$Fu -$epsU $pinchX $pinchY $damage1 $damage2 $betaMUsteel ; # hysteritic reinforcemnet model

i think it was an error of opensees.exe .i downloaded openseestk.exe and it worked.i have another problem that my output file gets loaded after closing only the opensees app.

For your recorders to save the outputs, you need to wipe out your results. For that, just add "wipe" to the end of your script.

Thank you, very much.I was every time closing my app and then loading the output and then again opening the app.
