Room 126

Abstract:

Foodborne illness remains a major cause of morbidity and mortality in the United States. An initial reduction of cases seen in the 1990’s in association with implementation of new regulatory systems has subsequently leveled off. In seeking to better understand factors underlying current disease trends, and to better assess the public health impact of these cases, we and others have worked on development of risk models for foodborne illness. Our group, as part of the Food Safety Research Consortium, has developed the Foodborne Illness Risk Ranking Model (FIRRM), which looks at a variety of potential public health impacts of food pathogen combinations. While the model has a number of strengths, it is limited by the availability of certain key data. Development of a rational national policy for prevention of foodborne disease will require significant investment in these and other risk models, to understand reasons for current trends, to serve as the basis for development of new regulatory approaches, and to appropriately target government spending on foodborne illness.

Dr. Morris is Director of the newly established Emerging Pathogens Institute (EPI) at the University of Florida, Gainesville. From 2000-2007 he served as Chairman of the Department of Epidemiology and Preventive Medicine at the University of Maryland School of Medicine, Baltimore (UMB), and from 2005-2007 was interim dean of the UMB School of Public Health. He has received his MD degree and a master’s degree in public health and tropical medicine from Tulane University, New Orleans. He served as an Epidemic Intelligence Service Officer in the Division of Enteric Diseases at the Centers for Disease Control in Atlanta from 1979-81. He is board-certified in both internal medicine and infectious diseases. Dr. Morris has authored over 60 textbook chapters and symposium proceedings and over 180 articles in peer-reviewed journals. He has had continuous federal grant funding since 1984; his scholarly contributions were recognized by election to the American Society for Clinical Investigation in 1996. He has served on four National Academy of Sciences expert committees dealing with food safety, and currently serves on the Institute of Medicine’s Food and Nutrition Board. Dr. Morris maintains an active research program in the area of emerging pathogens and enteric diseases, including ongoing work in India and Bangladesh. He also has extensive experience in work with antimicrobial resistance, including major papers on risk factors for infection with resistant microorganisms and on therapeutic approaches to control of such infections.

Self-Centering Damage-Free

Seismic-Resistant Steel Frame Systems

November 5, 2010

College of Engineering

Room 126

Abstract: Innovative self-centering (SC) moment resisting frames (SC-MRFs) and concentrically-braced frames (SC-CBFs) are being developed. In the SC-MRF, the beams are post-tensioned to the columns using high strength post-tensioning (PT) strands. A beam web friction device (WFD) is included in each beam-column connection to dissipate energy under seismic loading. The connection behavior is characterized by gap opening and closing at the beam-column interface. In the SC-CBF, the columns at the base are designed to decompress and uplift at a selected level of lateral loading, initiating a rigid-body rotation (rocking) of the frame. Vertically-aligned post-tensioning (PT) bars resist this uplift and provides a restoring force to return the SC-CBF to its support (to re-center the system). The SC-MRFs and SC-CBFs in this study are designed to meet two primary seismic performance objectives, namely, (1) no damage or residual drift under the Design Basis Earthquake (DBE), leading to immediate occupancy performance after the DBE, and (2) collapse prevention performance under the Maximum Considered Earthquake. A 4-story SC-MRF prototype building and a 4-story SC-CBF prototype building were designed for a stiff soil site in the Los Angeles area using performance-based design procedures with the above performance objectives. A 0.6-scale model of the SC-MRF and a 0.6-scale model of the SC-CBF were developed and tested at Lehigh University using the hybrid simulation method. Experimental results from these earthquake simulations are used to assess the design procedures.

Richard Sause

Lehigh University

Richard Sause is the Joseph T. Stuart Professor of Structural Engineering in the Department of Civil and Environmental Engineering and the Director of the Advanced Technology for Large Structural Systems (ATLSS) Engineering Research Center at Lehigh University. Over the past 21 years, he has directed or co-directed integrated experimental and analytical research on innovative self-centering earthquake-resistant systems; seismic performance of structures with supplemental dampers; new high performance steel highway bridge systems; seismic performance of concrete filled steel tube (CFT) columns and frames, and other topics. Dr. Sause was co-Principal Investigator of the NSF-funded project that developed the Real-Time Multi-Directional (RTMD) Earthquake Simulation Facility at Lehigh, which is part of the National Science Foundation’s George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES).

As ATLSS Director, Dr. Sause’s responsibilities include overseeing approximately $6 million in annual research expenditures and 25 support personnel and research scientists, and providing leadership to approximately 15 faculty and 45 graduate students and visiting research personnel. He is co-author of more than 80 peer-reviewed journal articles and more than 220 conference and workshop proceedings papers and technical reports. He has supervised or co-supervised 22 completed Ph.D. students.

Dr. Sause received his M.S. in 1983 and his Ph.D. in 1989 in Civil Engineering from the University of California at Berkeley, and received his B.S. in Civil Engineering from Rensselaer Polytechnic Institute in 1981.  He joined Lehigh University in 1989, after six years as a Senior Engineer and Consultant with SSD, Inc. He is a registered Professional Engineer in California. Dr. Sause was Class of 1961 Professor at Lehigh University from 1995 to 1998, and has been the Joseph T. Stuart Professor since 2003. He is a winner of the Raymond C. Reese Research Prize (American Society of Civil Engineers, 2009), J. James R. Croes Medal (American Society of Civil Engineers, 2007), the Charles C. Zollman Award (Precast/Prestressed Concrete Institute, 2006), the Raymond C. Reese Structural Research Award (American Concrete Institute, 1987), and the Best Paper, Journal of Architectural Engineering Award (American Society of Civil Engineers, 1997); he was part of a team that won the Charles Pankow Award for Innovation (Civil Engineering Research Foundation, 1997).
