Strand7 FEA software for Reinforced Concrete or Steel buldings?
(OP)
Hello. I am currently in the process of evaluating FEA soft-wares specially Strand7. I worked with OpenSEES and SAP2000 to assess potential of RC and Steel buildings against progressive collapse. I need to prepare a research proposal using Strand7 FE program. I would appreciate hearing from current Strand7 users about the advantages and disadvantages of this program to modeling RC and Steel buildings(for which type of building is better to use) and its capabilities to model Nonlinear dynamic analysis. Thank you.

They have recently started publishing "web-notes", which are intended for licenced users, but I imagine your local supplier would be able to give you access to those related to seismic analysis.

The Reinforced Concrete module is aimed more at post-processing plate / shell element results for design of reinforced concrete slabs (not beams and columns), but doesn't really affect the analysis phase - it is just a specialised post-processor.
Once you have a legitimate licence, you should get access to the Web Notes and the Verification Manual (and sample problems), which can be invaluable aids in setting up complex analyses, particularly if you need to use new modelling / analysis techniques that you have not used previously.
Let us know if you have any specific questions as to the capabilities of the program, and we'll try to help.

But surely the priorities of the people providing the funding are more important?

The simplest thing to model in Strand7 would probably be a simply-supported beam with a UDL or point-load at midspan. Steel can be "simpler" to model than concrete (if you are not going into plastic deformation etc), because it conforms quite well to a classical linearly-elastic material model, but you may need to model non-linear materials even for a simple beam if you are looking at plastic hinge formation, etc.
(The most "complicated" thing I have ever modelled in Strand7 was also a steel structure - a fire-damaged pressure vessel, for which I needed to model significant initial geometric imperfections due to previous fire damage buckling the shell, non-linear P-delta behaviour, tension stiffening, temperature-dependent material properties, and time-dependent loading and material properties. This took weeks to build the model, and the run-times were several days per run for the final model!)
