Backbone Curve Graph

[Kirkaguel offline]

Is there a way that we can see the backbone curve (whether bi-linear or trilinear) adopted for a non linear component i.e. plastic hinge in accordance with asce 41 guidelines?

One critical aspect of the backbone curve is the post peak stiffness assumption to capture cyclic degradation.

Since SeismoBuild is a fibre based program, this is not possible. Note however that in the next release a plastic hinge frame element with a multi-linear backbone curve will also be available.

Is there another method to model the post peak stiffness assumption for cyclic degradation modelling?

Unfortunately, no.
In fiber modelling this is automatically taken care by the constitutive material models for concrete and steel.
There is no need for the user to calibrate it.
