New MCEER Reports

MCEER technical reports are published to communicate specific research data and project results. Reports are written by MCEER-funded researchers, and provide information on a variety of fields of interest in earthquake engineering. The proceedings from conferences and workshops sponsored by MCEER are also published in this series.

MCEER’s web site offers a complete list of technical reports, abstracts, and prices. The publications catalog allows users to search the report list by subject, title and author, and to place orders for these reports. Visit the site at http://mceer.buffalo.edu/publications/default.asp.

Research Progress and Accomplishments: 2001-2003

This year’s annual summary of research and education achievements highlights work in progress on improving community resilience to earthquakes. Twelve papers are included, with contributions from over 80 researchers, practitioners and students. Topics include improving electric power networks, application and development of a wide range of advanced technologies, conceptualizing decision support systems, modeling and loss estimation, and the research-education interface.

The full color report can be downloaded from the publications section of our web site at http://mceer.buffalo.edu/publications/resaccom/0103/default.asp. A limited number of black and white copies are available by contacting MCEER publications.

Experimental Investigation of Light-Gauge Steel Plate Shear Walls for the Seismic Retrofit of Buildings

by J. Berman and M. Bruneau, 5/2/03, MCEER-03-0001, 212 pages, $35.00

This research investigates the use of steel plate shear walls (SPSW) with light-gauge cold-rolled infill plates for seismic retrofit applications. These systems may overcome the limitations of similar systems with hot-rolled infill plates. The report describes the use of plastic analysis to develop a design procedure for SPSW in seismic applications based on the strip model, the design of prototype light-gauge steel plate shear wall concepts in the context of the seismic retrofit of hospitals, and the testing of these prototypes under quasi-static conditions. The hysteretic properties of the specimens and the demands from the infills on the existing framing are then assessed, and the results of testing are compared with predictions made using the strip model. The experimental results showed that the entire infill of the light-gauge SPSW participated in dissipated energy. The adequacy of the strip model in predicting the monotonic behavior of light-gauge SPSW into the nonlinear range was also found to be acceptable through comparison with the experimental results.

Statistical Analysis of Fragility Curves

by M. Shinozuka, M.Q. Feng, H. Kim, T. Uzawa and T. Ueda, 6/16/03, MCEER-03-0002, 192 pages, $30.00

This report presents methods of developing bridge fragility curves on the basis of statistical analysis. It has unique pedagogical and archival features in that it (1) summarizes a number of journal and conference papers published earlier together with other unpublished materials arising from this study in a consistent manner, (2) includes damage data obtained from the 1994 Northridge and 1995 Kobe earthquakes shortly after the events, (3) shows how one can simulate a set of simulated damage data by Monte Carlo techniques, (4) provides statistical procedures for hypothesis testing and estimation of confidence interval for the parameters in the fragility model, irrespective of whether data are empirically or analytically developed, and (5) actual process of these testing and estimation is guided step-by-step using the archived damage data.

Proceedings of the Eighth U.S.-Japan Workshop on Earthquake Resistant Design of Lifeline Facilities and Countermeasures Against Liquefaction

edited by M. Hamada, T.D. O’Rourke and J.P. Bardet, 6/30/03, MCEER-03-0003, 680 pages, $60.00

About 100 researchers from both the U.S. and Japan participated in the 8th U.S.-Japan Workshop on Earthquake Resistant Design of Lifeline Facilities and Countermeasures Against Liquefaction, held in Tokyo, Japan on December 16-18, 2002. The main themes of the workshop were response and design of pipelines subject to permanent ground deformations; design, mitigation and rehabilitation of lifeline systems; advancing the state-of-the-art of liquefaction hazard mapping; fault ruptures, ground movement and their effects on structures; evaluation of seismic performance of lifeline systems; liquefaction potential and characteristics of soils by field and laboratory experiments; behavior of piles in liquefied and laterally spreading ground; and ground motion characteristics and liquefaction. The proceedings contain over 50 papers, the agenda and list of participants, and the summaries of the workshop reporters. Summary information about this workshop is available on MCEER’s web site at http://mceer.buffalo.edu/publications/reports/docs/03-0003/default.asp.
