NHERI-SimCenter/EE-UQ v1.1.0

This open-source research application  provides an application researchers can use 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 the simulation software and the user make simplifying assumptions in the numerical modeling of that structure. In the application, the user is required to characterize the uncertainties in the input. The application will after utilizing the selected sampling method, will provide information that characterizes the uncertainties in the response measures. The computations to make these determinations can be prohibitively expensive. To overcome this impediment the user has the option to perform the computations on the Stampede2 supercomputer. Stampede2 is located at the Texas Advanced Computing Center 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.
