@ University of California-San Diego This research effort aims to study experimentally the effect of earthquake-induced lateral spreading due to liquefaction on pile foundations, both in full size and centrifuge model conditions. Comparable tests of instrumented single piles and pile groups embedded in 1-and 2-layer soil profiles will be conducted in slightly inclined laminar boxes subjected to base shaking at three facilities: 1) The 100g-ton geotechnical centrifuge, laminar box and in-flight shaker at RPI, 2) The 6m high laminar box and 1g shaking table at NIED, Japan (largest laminar box in the world), and 3) the 1.9m high laminar box and 1g shaking table at UCSD (largest laminar box in the US). Taking advantage of the successful experience at RPI in this kind of testing, this research constitutes the first opportunity for direct comparison of results in controlled experimental environments between centrifuge and full sized tests to be conducted at NIED. Additionally, centrifuge and full size NIED results will be used to validate the medium-size experiments to be performed using the UCSD shaking table and laminar box. Advanced data analysis techniques-including system identification and visualizations-will be used to process and compare the results from the three facilities, with engineering interpretations and computer simulations. |

Neesr-Sg; Seismic Performance of Bridge Systems With Conventional and Innovative Materials @ Board of Regents, Nshe, Obo University of Nevada, Reno Intellectual Merit: The primary technical objective of the proposed study is to conduct a comprehensive investigation of the seismic performance of a series of models of four-span large-scale bridge systems including the soil-structure interaction effects at the footings and the abutments. A strong interdisciplinary team of researchers is formed to lead the effort in the study of the shake table response of bridge models, soil-structure interaction, numerical simulation, innovative materials, and wireless sensors with an overarching effort in education and outreach and utilization of information technology. Two leading international collaborators and representatives from the design profession will be also involved. Through the use of NEESgrid system and its tools, the team members and their students will closely collaborate in his multi-faceted study. Extensive numerical and physical simulation studies are envisioned, with the former using program OpenSees and the latter using the NEES shake table facilities at the University of California, San Diego (UCSD) and the University of Nevada, Reno(UNR). A large-scale abutment will be tested at UCSD and four, large-scale, 4-span bridge models will be tested at UNR. The UCSD studies will provide data that will be used in simulating the abutment input motion in the UNR tests. Two of the bridge models will incorporate conventional design, the third will be supported on fiber-reinforced polymer (FRP) composite piers, and the fourth will incorporate innovative column plastic hinges with minimum permanent damage. The major gap that the proposed study will address is experimental data and calibrated analytical studies of the earthquake performance of bridge systems. Unlike past studies that have generally been on components, the proposed research will include system response in addition to component behavior. Modern wireless sensors will be further developed as a part of this project and used in the shake table studies. The results of the study are expected to facilitate the evaluation of existing and emerging bridge seismic codes, provide information for performance-based seismic design, help understand the system response, determine the effectiveness of FRP piers, evaluate potential of wireless sensors in large-scale testing, and demonstrate the feasibility of innovative serviceable bridge columns after strong earthquakes. New data and metadata models are envisioned to facilitate incorporation of the new information obtained in the project in the data repository planned by the NEES Consortium. |

Towards Petascale Simulation of Urban Earthquake Impacts @ Carnegie-Mellon University This award is an outcome of the NSF 07-559 program solicitation, "accelerating Discovery in Science and Engineering through Petascale Simulations and Analysis" competition. The lead institution is Carnegie Mellon University, with subawards to the Universities of California at Berkeley, Davis, and San Diego. This award will develop methodologies, capability, and software for high-fidelity, physics-based petascale simulations of an entire high seismicity urban region, the Greater Los Angeles Basin (GLAB), to assess the engineering impacts of large magnitude earthquakes on buildings, transportation system components, and the underground civil infrastructure. Earthquakes are one of the most severe natural hazards facing the United States. Simulating their effects on the built environment is a unique science driver for petascale high-performance computing (HPC) systems because of the multiple length scales with different physics, large data volumes, and need for highly scalable parallel visualization and data querying. Current three-dimensional earthquake simulations have been limited to linear soil behavior and isolated, individual structures. Advancing beyond current approaches, this project will develop simulation capability that includes the interaction between the soil, foundations, and large inventories of structures; the interaction between structures in densely built areas; and the effect of the structures on the free-field motion; as well as the nonlinear soil behavior and the effect of the pore water pressure in saturated soils leading to liquefaction. Current HPC capability is inadequate for these complex simulations. This project will use emerging petascale systems to perform and integrate (1) ground motion simulation of large sedimentary basins, (2) simulation of the nonlinear behavior of soil, (3) simulation of large inventories of buildings, bridges, and other infrastructure systems, (4) computational databases, and (5) scalable visualization techniques. The project will make new advances in a hierarchical, multi-scale methodology for petascale simulation. Going from a large regional, broadband earthquake simulation to multiple subregions will allow detailed modeling in a highly scalable manner to capture site response and structural response accurately for entire inventories. The Domain Reduction Method will be applied for the first time using ground motion from a regional simulation as input for multiple highly populated subregions. These subregions include models of highly nonlinear soil and detailed models of hundreds of buildings and bridges along with embedded foundations. A new scalable implicit-explicit time integration method will be developed to provide optimal computational performance for the complex earthquake simulations for a subregion. Data analysis and visualization capability will be developed to run on the same parallel processors as the simulation, drastically reducing the need to move data. Using this approach for data-intensive supercomputing, in-situ visualization and a new computational database system will allow unprecedented ability to understand earthquake impacts. The new capability will present information that facilitates understanding and decision-making by drilling down to the detail of interest while maintaining the global context. The GLAB was selected because of the high seismic risk, important public policy need, and the wealth of information that it provides for verification and validation. The annual milestones for the GLAB test bed are calibrated to take early advantage of HPC resources, with scaling of the simulations to take place as petascale systems are brought online. The methodology, applications, and the results of the simulations will be useful for disaster planning and management, since it is the detailed knowledge of how an urban system performs in a large earthquake that is needed for improving disaster preparedness and mitigation. Graduate students working on the project will have the opportunity to create new knowledge through multidisciplinary research in civil engineering, computational engineering, and computer science. |

Neesr-Ii: a Seismic Study of Wind Turbines For Renewable Energy @ University of California-San Diego This award is an outcome of the NSF 08-519 program solicitation George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Research (NEESR) competition and includes the University of California, San Diego (UCSD) (lead institution) and Harvey Mudd College (sub-award). This project will utilize the NEES equipment sites at the University of California, Los Angeles (UCLA) and the University of California, San Diego (UCSD). The research outcomes will allow engineers to appropriately and economically account for seismic loading on wind turbines. This will further facilitate expansion of a main source of Green renewable energy, and ensure minimal disruption to the critical resource that wind power provides. The project will be conducted in collaboration with industry representatives in order to further focus the research effort on the most significant practical needs today. Related educational outreach activities will allow undergraduate students to participate in the utilization of the involved NEES world class testing facilities. In addition, the project team will develop related internet dissemination applications for K-12 and undergraduate students. In the United States, the 2006 investment in wind turbines was on the order of $4 billion. This growth shows no sign of slowing with the Department of Energy (DOE) goal of expanding the number of wind turbines fivefold by 2015. A significant portion of this growth is in earthquake prone states. For instance, more than a quarter of the new capacity installed in 2005 and 2006 was in the seismically vulnerable States of California and Washington. New wind turbines are also becoming increasingly taller and heavier, standing vertically in excess of 200 feet (taller than a twenty-story building), and thus increasing the significance of potential earthquake loads. If seismically vulnerable, numerous turbines of a given vintage in a large wind farm may be damaged, leading to substantial economic consequences. In order to address this challenge, the proposed research will utilize NEES facilities to provide the needed experimental data and insights for developing validated rational analysis and design procedures. The NEES equipment operated by UCLA will be used to conduct a comprehensive field investigation to quantify the dynamics of actual operating wind turbines. Experiments using the outdoor UCSD NEES shake table will provide insight into the potential damage modes of wind turbines when subjected to earthquake shaking. Findings from these tests will be used to construct and validate computational models that will further extend the testing results. These models will be used to develop a framework for seismic analysis and design of wind turbines. Intellectual merit in this effort stems from providing the first experimentally validated seismic design procedure for wind turbines worldwide. Data from this project will be made available through the NEES data repository (http://www.nees.org). |

Neesr-Cr: Earthquake Performance of Full-Scale Reinforced Soil Walls @ University of California-San Diego This award is an outcome of the NSF 09-524 program solicitation "George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Research (NEESR)" competition and includes the University of California-San Diego and New Mexico Tech (subaward). This project will utilize the NEES equipment site at the University of California-San Diego. The dynamic response and performance of earth retaining structures has traditionally been measured by testing small physical models, which have yielded valuable information but represent a compromise with respect to field structures. What is needed for a better understanding of the earthquake performance of soil retaining walls is full-scale testing. The objective of the project is to perform a unique experimental investigation of the earthquake performance of full-scale (10 m) reinforced soil retaining walls constructed using realistic materials and methods. Considering that these walls will be several times taller than for any previous research, a key focus of the proposed work will be the influence of wall height on overall system response and distribution of dynamic forces in soil reinforcement. Other focus areas will be dynamic earth pressure on the back of the wall, effects of dynamic loading on load transfer mechanisms between soil and reinforcing elements, and permanent wall deformations after dynamic loading. |

Sustainability and Performance-Based Ground Stabilization Assessment @ University of California-San Diego Sustainability is increasingly becoming a major concern in construction and development of the built infrastructure. Systematic inclusion of environmental impacts and life-cycle costs as metrics in performance-based engineering frameworks is a primary objective of this research. In order to develop the quantitative integrated elements of such a framework, attention is placed on ground improvement (stabilization) in seismic regions, as a representative geotechnical engineering area of major economic and environmental consequences. Researchers with complementary expertise from the University of California, San Diego (UCSD) and the University of Central Florida (UCF) are collaborating on this effort. The study will develop and implement for use an extended performance-based framework for ground improvement that incorporates economic impacts and carbon footprint metrics; advance the computational modeling capabilities related to the seismic performance of improved ground through calibration and verification using data from case histories and model testing; and report the probabilistic sustainability results in terms of risk/expense and carbon equivalent outcomes, suitable for decision-making considerations. In conducting this research, available data on the studied ground improvement techniques will be coalesced and analyzed. An existing soil constitutive model will be extended to more accurately capture post-liquefaction reconsolidation settlement behavior, based on a better understanding of the volumetric strain distribution and settlement patterns of the improved ground (including the influence of foundation loading on post-liquefaction settlement). The open source platform OpenSees will be employed for conducting the underlying Finite Element (FE) computations. A rigorous probabilistic performance-based engineering framework that integrally includes sustainability considerations will be developed and numerically implemented for ground improvement analysis and design. Building information modeling (BIM) techniques will be used to integrate geotechnical data, carbon-footprint, and spatial settlement scenarios with post-earthquake repair and sustainability metrics. Direct input from practitioners will guide all phases, with the overall goal of advancing the state-of-the-art and state-of-practice in ground improvement analysis and design. On this basis, different ground improvement options will be evaluated, towards the decision-support process. Finally, analysis and design tools based on this extended PBEE sustainability framework will be developed for efficient practical implementation. |

@ University of California-San Diego This project supports a cooperative research project by Dr Ahmed Elgamal, University of California-San Diego in collaboration with Dr. Khaled El-Zahaby, Chairman, Housing and Building national Research Center (HBRC) in Cairo, Egypt. They will performe a Seismic Risk Assessment of Wind Turbine Towers in the Zafarana Wind Farm in Egypt. The Zafarana wind farm in 2012 was generating a capacity of 517MW, making it one of the largest onshore wind farms in the world. It is located in an active seismic zone along the west side of the Gulf of Suez. An extension of the wind farm southward is under consideration for construction in the near future. Seismic risk assessment is needed to assess the structural integrity of wind towers under expected seismic hazard events in this location, and this risk assessment procedure is likely to be valuable whenever wind turbines are located in a potentially active seismic region. The project objective is to pursue interdisciplinary studies to define seismic risk and seismic loads via a range of seismic analyses that are coupled with measured structural values in the field. The ultimate goal is to define and improve seismic design of wind turbine structures. |
