Completed Projects

NEESR-GC: Seismic Risk Mitigation for Port Systems
Wharf Pier
This project integrates engineering, logistics, risk analysis, and decision sciences and uses the performance of the port system as the basis for seismic risk mitigation decisions.
Performance Evaluation of Semi-rigid Steel Frames
Beam Column
Full-scale hybrid simulation of a semi-rigid steel frame is conducted and its ductility and drift ratios are studied.
Framework for Development of Hybrid Simulation in an Earthquake Impact Assessment Context
NEES-SD
The objective of this project is to develop an earthquake impact assessment framework that integrates hybrid simulation with free-field and structure sensor measurements, system identification-based model updating technology, probabilistic fragility analysis, and existing earthquake loss assessment software.
Controlled Rocking of Steel-Framed Buildings With Replaceable Energy Dissipating Devices
Controlled Rocking
This research aims to develop a new structural system that employs controlled self-centering rocking action and replaceable structural fuses to provide safe and cost effective resistance to earthquakes. The system combines desirable aspects of conventional steel-braced framing with innovative self-centering rocking action that employs high strength post-tensioning and replaceable shear fuses.
Evaluation of the Response of Planar, C-Shaped, Coupled-wall, and Core-wall Systems
Complex Walls
Eight large-scale wall specimens were tested, including 4 planar (rectangular) walls and 1 coupled wall.
Siesmic Simulation and Design of Bridge Columns under Combined Actions and Implications on System Response
CABER Vertical
The objectives of the project are to develop a fundamental knowledge of the impact of combined actions on column performance and system response and to establish analysis and design procedures that include the impact at both the component and system levels. The objectives will be realized by integrating analytical and experimental research where physical tests are driven by analyses and simulations that examine the system response of various bridge types under different loading conditions.
Multi-Site Soil-Structure-Foundation Interaction Test (MISST)
MISST
The Multi-Site Soil-Structure-Foundation Interaction Test (MISST), conducted by collaborating partners at University of Illinois at Urbana-Champaign (Illinois), Rensselaer Polytechnic Institute (RPI), and Lehigh University (Lehigh) is presented. The project was developed to provide a realistic test bed application with which to verify and extend all components of the NEESgrid as well as all components of the sites taking part in the distributed simulation. Concurrently, it has extended and represents the current state-of-the-art in distributed and integrated experimental-analytical earthquake engineering simulation.
