Introduction

The University at Buffalo’s Structural Engineering and Earthquake Simulation Laboratory (SEESL), which is the flagship laboratory in the Multidisciplinary Center for Earthquake Engineering Research (MCEER), will be an important node in the National Science Foundation’s George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES). Under NEES, SEESL’s capabilities will be significantly expanded, with key elements of the upgrade including large-scale dynamic and static actuators, high performance control systems, a greatly expanded strong floor, and a large reaction wall – all of which will be integrated with a new set of two moveable shake tables.

The intent of the NEES Node project at UB is to develop the most versatile earthquake engineering research facility possible, designed to provide testing capabilities that will revolutionize the understanding of how very large structures react to a wide range of seismic activity, even when tested to complete failure. The facility will be capable of conducting testing of full or large-scale structures using static or dynamic loading. The use of modern techniques such as Pseudo-Dynamic, Effective Force, and Real-Time Dynamic/Pseudo-Dynamic Hybrid will be possible, along with conventional Static, Quasi-static, and Dynamic Force techniques. Real-Time Dynamic Hybrid Testing (RTDHT) is a new form of testing being explored at UB in which shake table and/or dynamic force experiments on substructures are combined in real-time with computer simulations of the remainder of the structure. This provides a more complete picture of how earthquakes would affect large structures, including buildings and bridges, without the need to physically test the entire structure.
