6. Requirements¶
The following contains the functional requirements for the EE-UQ application. These requirements are broken down into a number of groups, general, earthquake loading, building description, analysis, and UQ.
The purpose of presenting these requirements is to inform the community on the present capabilities of the EE-UQ application and features that could be added. The original set of requirements have come from a set of grand challenge reports, GC. These original requirements have been broken into a smaller set of deliverable features by the senior faculty associated with the project, SP. Additional requirements have come from users through the User Forum, UF. See section Feature Requests if you have additional features you would like to see.
