There is some error while computing Time period using viscous damper in python and Tcl. I think there is error in tcl version as time period does not changes with addition of viscous damper. Change the viscous damper with # uniaxialmaterial # -*- coding: utf-8 -*- """ Created on Wed J...

I used the single bay frame with viscous damper from the example. When I checked the time period with and without viscous damper it is same in tcl version. In python version the time period changes when using viscous damper. Change the uniaxialmaterial with # for viscous damper wipe all; # clear mem...

I downgraded to version 3.4.0.7 but it didn't work. Got same error

I upgraded to version 3.4.0.8 but still I got WARNING material type ASDConcrete3D is unknown.

Although the material is available in the opensees documentation. But it gives WARNING material type ASDConcrete3D is unknown

Thankyou. I understood the local axis x will orient along the global Y-axis with the zeroLengthSection [0,1,0]. But what is the reason, why we are restraining in X direction?

I am confused to fix boundary for zerolengthsection. Should I fix x and y direction and release the rotation?
ops.node(3, 0.0,0.0)
ops.node(1, 0.0,0.0);
ops.node(2, 0.0, H)
ops.fix (3, 1, 1, 1);
# Fix for zerolengthsection
ops.fix (1, 1, 1, 0);
ops.element ('zeroLengthSection' ,2, 3, 1,.....

Is there analysis('Creep') command for time dependent material TDConcreteMC10
