Go into your ResearchGate research section after your profile, and there is a heading that you can 'click' on to allow you to add research. Please see shot of my page.

I hope this helps.

ResearchGate is a professional network for researchers, not a traditional journal publisher, so articles are usually uploaded after publication elsewhere. To share your article, first publish it in a peer-reviewed journal. Then create a ResearchGate profile, and upload a full-text version of your published paper (if copyright allows) to your profile. Engage with the community by sharing your work and responding to feedback.
