News of the Institute
Following the National Science Foundation (NSF) decision to not move forward with an award for NEES2 Operations, EERI President Ian Buckle sent a letter of concern to NSF on behalf of the EERI Board of Directors. The October 30, 2013 letter expresses unease about this decision and the lack of specifics or a timeline for the announcement of an alternate plan.
NSF has since replied saying the federal shutdown in October and budget uncertainties have led to this delay and, in the meantime, researchers should be aware that proposals are being accepted for use of the NEES facilities through the usual channels.
EERI played an active role in the establishment of the George E. Brown Jr. Network for Earthquake Engineering Simulation (NEES) more than a decade ago, and has watched it grow and mature into a remarkably successful program in earthquake risk reduction. Since its creation, NEES has become a key part of a community-wide effort to enhance the seismic resilience of the nation and has played a unique and essential role in this regard.

Former students of Professor Emeritus Andrei M. Reinhorn (M. EERI, 1986), at the University at Buffalo, organized a symposium to commemorate his storied career and lifetime achievements on Monday, September 30, 2013.
Andrei M. Reinhorn, P.E. and Ph.D., is a former Clifford Furnas Eminent Professor in the Department of Civil Structural and Environmental Engineering at the University at Buffalo (SUNY), where he taught courses in structural engineering with emphasis on experimentation and simulations in structural dynamics and earthquake engineering. He conducted experimental and analytical research on structural control and the inelastic seismic behavior of buildings and bridge systems. He performed experimental studies and developed computational tools using generic macro-models for simulation of inelastic behavior of structures during progressive collapse.
He published over five hundred articles and reports in archival journals, conference proceedings, and institutional publications. He developed several computer platforms on inelastic analysis (IDARC series) and seismic isolation (3DBASIS series), currently used by engineers and researchers around the world. He was a member of MCEER's executive committee and directed the networking program.
Reinhorn served as the first Director of the University at Buffalo's Structural Engineering and Earthquake Simulation Laboratory, hosting the most versatile equipment site of the George E. Brown Network for Earthquake Engineering Simulation (NEES). He served as one of the founding members of the Board of Directors of NEESinc., the organization that coordinated the new network, and is the past chair of the NEESinc Data Sharing and Archiving Committee.
At the University of Buffalo, Reinhorn served as the Chair of the Department of Civil, Structural and Environmental Engineering, on the Presidential Review Board, and on other departmental, school, and university committees. In 2011, he received ASCE's highest honor, the Nathan M. Newmark Medal. Among other awards, he received the 2007 SUNY Chancellor Award for Excellence in Scholarship and Creative Activity and the 2005 ASCE-CERF Charles Pankow Award for Innovation.Back to top >

In September, a team of EERI members and colleagues visited the areas of New Zealand affected by the 2010 and 2011 Canterbury earthquakes. The New Zealand field visit was part of an initiative to document Building Back Better practices being developed by the European Union, the United Nations Development Program’s Bureau for Crisis Prevention and Recovery, and the World Bank’s Global Facility for Disaster Reduction and Recovery (GFDRR) .
The following EERI members traveled to New Zealand for the field visit: Scott Miles (M. EERI, 2009), Western Washington University, and Dana Brechwald (M. EERI, 2013), Association of Bay Area Governments. The following experts also joined the team: Katalin Demeter, GFDRR, World Bank; Rachel Davidson (M. EERI, 1995), University of Delaware on sabbatical at the University of Canterbury; David Johnston (M. EERI, 2013), GNS Science and Massey University; Stefano Pampanin (M. EERI, 2011), University of Canterbury and, President, New Zealand Society for Earthquake Engineering; Sarah Beaven and Sonia Giovinazzi, University of Canterbury; Suzanne Wilkinson, Sandeeka Mannakkara, and Tinu Rose, University of Auckland.
The team aimed to track Building Back Better practices that led to successful outcomes with a specific emphasis on housing, land-use planning, insurance, commerce, the seismic design code, and infrastructure. The field visit was comprised of a series of interviews with government and non-government officials, interviews of the resident population in reconstructed and resettled locations, as well as an informal survey of the building structures in the central business district.
The New Zealand field visit was funded by a grant agreement between EERI and the GFDRR at the World Bank. A report on the Building Back Better practices and lessons learned will be available early next year.Back to top >
Be sure to stop by the EERI booth (space 741) at this year's AGU Fall Meeting at the Moscone Center (Hall D) in San Francisco, California.
The Institute invites EERI members who will attend the 2013 AGU Fall Meeting to visit the EERI booth and connect with old and new colleagues. The EERI booth will feature a game, best-selling monographs, special and themed issues of Earthquake Spectra, and other resources. EERI staff will be on hand to provide meeting participants with information about the Institute.
The EERI booth is open: Tuesday to Thursday, Dec. 10-12, 9:30 a.m. – 6:00 p.m.; and Friday, Dec. 13, 9:30 a.m. – 1:30 p.m.
The site amplification factors used to develop design-basis ground motions will be changing in the next revisions of several building code documents due to research conducted as a part of the Pacific Earthquake Engineering Research Center’s (PEER) NGA-West2 project. The new site factors have been approved by the Provisions Update Committee of the Building Seismic Safety Council and are expected to appear in the 2015 version of the NEHRP Provisions, followed shortly thereafter by ASCE-7 and various building code documents.
Engineers use site factors to modify ground motions from a reference rock site condition to reflect the influence of geologic conditions at the site of interest, i.e. the location where a new building is being constructed. These factors, commonly called Fa, Fv, and FPGA are found in Tables 11.4-1, 11.4-2, and 11.8-1 of the ASCE-7 code and have not been updated in several decades.
Experience in practice and from research indicates that the current NEHRP site factors, developed in the early 1990s, have discrepancies that are consequential for ground motion hazard analyses, loss estimation, and other applications. To resolve these issues, the new NGA-West2 ground motion data set was used by PEER researchers to develop a new site amplification model, which was then used to update the NEHRP site factors. Because the updated site factors operate seamlessly with the NGA-West2 GMPEs (which will soon be applied for the next-generation seismic hazard maps used in the code), a long-standing problem in earthquake engineering will be resolved.
PEER researcher Jonathan Stewart (M. EERI, 1994) from UCLA led this effort and is the first author of PEER Report 2013/13 that proposed the new factors. This report titled “Semi-Empirical Nonlinear Site Amplification and its Application in NEHRP Site Factors” is available for free download at PEER’s NGA-West2 website .

NEES/EERI Webinar, Nov. 20: From Large Scale Test Findings to Cost-Benefit Analysis of Base-Isolated Buildings
Date: Wednesday, November 20, 2013
Time: 11:00 a.m. – 12:30 p.m. Pacific Time (U.S. and Canada)
Presenters: Keri Ryan (M. EERI, 1999), University of Nevada, Reno; Anthony Giammona, Nabih Youssef & Associates; Gilberto Mosqueda (M. EERI, 2001), University of California, San Diego; and Stephen A. Mahin (M. EERI, 1975), University of California, Berkeley.
Seismic isolation has long been regarded as an effective technique to enhance the seismic performance of structures, but applications to new buildings have been limited in the United States. The following reasons have often been given for the slow growth of applications for seismic isolation systems: the high cost premium of isolation coupled with inability to convey the potential benefit to building owners; lack of field or laboratory data on full-scale, realistic buildings; and uncertainty about the response of isolated structures in extreme ground motions that exceed design levels.
This NEES/EERI research-to-practice webinar will present findings from the recently completed NEES TIPS (Tools for Isolation and Protective Systems) project. The project was designed as a comprehensive research and education program to facilitate the wider adoption of seismic isolation systems for the superior protection of structures. This webinar will focus on three main topic areas:
1) Findings from a full-scale test program on isolated and conventional structures conducted at E-Defense. Among the highlights, new knowledge is presented about the influence of vertical excitation on the response of nonstructural components and contents in base-isolated and conventional buildings. Furthermore, the test results from the E-Defense tests are used to validate and make recommendations regarding modeling procedures applied by practitioners for the design of base-isolated buildings.
2) Findings from limit state tests on isolated buildings conducted at the University at Buffalo NEES facility. Based on calibrated results from the limit state tests, a FEMA P695 procedure is applied to assess the behavior and collapse capacity of isolated buildings considering pounding against a moat wall.
3) Results from comparative life cycle cost-benefit analysis of base-isolated buildings. These results are interpreted within a broader FEMA P58 framework for practicing engineers to develop results to present to owners who are choosing between minimum code compliance and various enhanced performance designs.
Information about registration for this NEES/EERI Webinar will be available soon at http://nees.org/events/details/246 .Back to top >
