Abstract

The Network for Earthquake Engineering Simulation (NEES) project aims to advance collaborative earthquake engineering research in the United States by improving facilities for physical and computational earthquake simulations and encouraging the sharing of data, facilities, and computational models.
Traditionally, earthquake engineers have simulated the effects of ground motion on structures using one of two basic approaches: using computational simulations or using physical simulations. More recently, earthquake engineers have begun doing hybrid experiments: coupled computational and physical simulations in which one part of a structure is modeled computationally and another part is modeled as a physical experiment. The computational and physical simulations are run simultaneously; the results of both the computational and physical component for one time-step are used to determine the inputs to each for the next time-step. Hybrid experiments have generally been tightly coupled, with the computational system and the physical control system communicating via a shared-memory backbone.
