Why are there no browser-based FE Analysis and Design Solution?
I have tried googling this, but I was not able to find any STAAD type software that allows me to analyse and design structures from the browser.
Currently we do not have any such solution and I am not aware whether anyone else has anything similar to what you are looking for. In future there is a possibility that we may allow STAAD(X) to run on cloud with the front end user interface running on a browser.
