I need to work on effect of material degradation on fragility function of RC building. For this I need to perform IDA. My first choice for this is Seismo Struct if I get academic license for this. What other tool can be used for this purpose
I would recommend:
1- OpenSeesMP (the multi-parallel version of OpenSees)
2- OpenSeesSP (single parallel) with Matlab procedure to run the IDA
3- OpenSees (sequential) with Matlab procedure to run the IDA
You may also use ZEUS-NL (free -open source). Its extreme efficiency, accuracy, verification and user-friendly graphical user interface.
My recommendation is to use SAP2000 which is from my point of view the most efficient tool for dynamic linear and non-linear analyses of RC buildings with shear walls. In the analysis of such buildings you can apply the "Melkumyan Hysteresis Model" to better describe the shear behavior of the structure under your consideration.
I think SAP2000 can be a good option and seismostruct too but for the last I haven't used it yet just lot of researchers use that one in their papers.
Depends on the model you use in your research. For nonlinear dynamic simulations I would recommend LS-DYNA. You can use the student version of Ansys LS-DYNA if your model does not exceed 128K nodes/elements.

When it comes to performing a large number of nonlinear time-history analyses, there is no software that can compete OpenSees. Not only it is much faster than other software like SAP2000 or ETABS but also it benefits from the "fiber section" method to consider material nonlinearity (compared to plastic hinges). On the other hand, there is much more flexibility using OpenSees since you are writing your own code and you can define the specific outputs you need. Think about post-processing a large amount of data from IDA analysis. You can also use the OpenSees module (OpenSeesPY) in Python to do any post-processing or visualization you want. On top of all, it's FREE!
I recommend using OpenSeesPy. It is way faster than SAP2000 or ETABS. There is high flexibility in using the material library. It might be little difficult at first in OpenSees, since it is all CUI and you have to do a lots of programming but once you get habituated, this is the best option not only for analysis purpose but also for your deeper understanding of the works that your will be going.
SeismoStruct, Very powerful and user-friendly. Here is a tutorial in my Chanel that may be helpful.https://www.youtube.com/watch?v=c1k2YfwJBCM&list=PLyb0toWDshmmTU0e4PYxF4cKwS5vIQxMG
