I am trying to model the shear link in sap2000/ etabs by I do not know how to model the web stiffened beam in this software because for the shear link we have to use web stiffness.
Please suggest how to do it.
I want to perform a nonlinear dynamic analysis of this model.
You can not model web stiffened beam . You can only adjust the shear strength in the overwrites.
Dear Mohd Ubaid
The web stiffeners cannot be modeled in SAP2000 explicitly. However, the plastic hinges of the link can be defined considering the presence of intermediate web stiffeners. It is suggested to read following paper for more information.

Dear Mohd Ubaid
you can either use ASCE 41 recommendation in steel chapter or use the following paper which uses a shear spring as the representation of shear link. The web stiffener spacing has been taken into account in this paper. You can use only monotonic parameters for your modelling if you are using sap and aren't interested in deterioration.
Article Predictive equations for shear link modeling toward collapse
I have also shown how you can make a model in OpenSees based on this method which can be also used in SAP.

There are other approaches like modelling the shear link with an elastic element with two shear springs at its ends which has been discussed in the following paper.

I have also talked about and compared all other methods that I have seen in the literature in the following paper:
