2. About

This is an open-source research application, which is available at EE-UQ Github page, is released under a BSD Clause 2 license. The EE-UQ app can be used to predict the response of a building subjected to earthquake events. The application is focused on quantifying the uncertainties in the predicted response, given the that the properties of the buildings and the earthquake events are not known exactly, and that both the simulation software and the user make simplifying assumptions in the numerical modeling of that structure. In this application, the user is required to characterize the uncertainties in the input. The application will, after utilizing the users selected sampling method, provide information that characterizes the uncertainties in the computed response measures. As the computations to make these determinations can be prohibitively expensive to perform on a user’s local computer, the user has the option to perform the computations remotely on the Stampede2 supercomputer. Stampede2 is located at the Texas Advanced Computing Center (TACC) and made available to the user through NHERI DesignSafe, the cyberinfrastructure provider for the distributed NSF funded Natural Hazards in Engineering Research Infrastructure (NHERI) facility.

Whether running locally or remotely, the computations are performed, as will be discussed in Technical Manual, in a workflow application. That is, the numerical simulations are actually performed by a number of different applications. The EE-UQ app backend software runs these different applications for the user, taking the outputs from some programs and providing them as inputs to others. The design of the EE-UQ app is such that researchers are able to modify the backend application to utilize their own application in the workflow computations. This will ensure researchers are not limited to using the default applications we provide and will be enthused to provide their own applications for others to use.
