At its recent annual meeting in Victoria, British Columbia, the Western States Seismic Policy Council awarded the California Seismic Safety Commission its Overall Excellence and New Technology Award for the recently released ATC-40 report, SEISMIC EVALUATION AND RETROFIT OF CONCRETE BUILDINGS. Prepared by the Applied Technology Council under the Commission's Proposition 122 Retrofit Practices Improvement Program, the 2-volume, 612-page, report provides a state-of-the-art methodology for the seismic evaluation and retrofit of concrete buildings.

Accepting the award on behalf of the Commission and the Applied Technology Council (ATC) was Mr. Craig Comartin, ATC Senior Structural Consultant and ATC-40 Project Principal Investigator (PI). In his brief acceptance speech, Mr. Comartin commended the Commission, its staff, and the 18-person consulting team who produced the report for ATC: Richard Niewiarowski (Co-PI and Project Director), Christopher Rojahn (Senior Advisor), Sigmund Freeman, Sunil Gupta, Thomas Hale, Ronald Hamburger, William Holmes, Charles Kircher, Marshall Lew, Gregory Luth, Geoffrey Martin, Lelio Mehia, Jack Moehle, Yoshi Moriwaki, Maurice Power, Wendy Rule, Thomas Sabol, Gail Shea, and Nabih Youssef.

The report was recognized for its clear, concise, and beautifully formatted and illustrated descriptions of new and emerging technologies for evaluation and retrofit of older concrete buildings. Making the report doubly valuable is the fact that the methods are applicable to most building types (i.e., not only concrete buildings). Specific guidance is provided on performance objectives, seismic hazard, determination of deficiencies, retrofit strategies, quality assurance procedures, nonlinear static analysis procedures, modeling rules, foundation effects, response limits, and nonstructural components.
Copies of the report can be obtained from the Applied Technology Council (555 Twin Dolphin Drive, Suite 550, Redwood City, California 94065; Telephone, 650/595-1542; Fax, 650/593-2320).; E-mail: This email address is being protected from spambots. You need JavaScript enabled to view it..


What's New?

What's New? The ATC Hazards by Location website allows the user to find site-specific basic wind speeds, ground snow loads, tornado design wind loads, and seismic loads used in the standards published by the American Society of Civil Engineers, National Earthquake Hazards Reduction Program, and International Building Code. This website was developed with the financial help of the ATC Endowment Fund, Federal Emergency Management Agency (FEMA), Insurance Institute for Business & Home Safety (IBHS), and Metal Building Manufacturers Association (MBMA), and is free of charge to users.
