FEMA P-2012, Assessing Seismic Performance of Buildings with Configuration Irregularities

The NEHRP Consultants Joint Venture, a partnership of the Applied Technology Council (ATC) and the Consortium of Universities for Research in Earthquake Engineering (CUREE), is developing a data repository to document and publish information collected after the 2010 Maule Earthquake in Chile for the National Institute of Standards (NIST). This work is being led by Purdue University. The effort has two objectives:

  1. document, preserve, and disseminate valuable data pertaining to affected engineered structures with properties similar to those of structures in the U.S.
  2. develop a framework that can be used to document key information about the structural response of building structures to future earthquakes.

The data repository will also serve as a prototype for NIST’s recently initiated multi-year project to create a digital archive of data related to natural and man-made disasters as well as failure studies. This initiative promises to significantly improve the ways in which engineers help communities to prepare against disasters and structural failures. The availability of systematically organized field data would enable better procedures to vet design and evaluation tools, providing structural performance data with less stringent limitations about scale and applicability than data obtained through experimental and numerical simulations.

The NEHRP JV asks that you consider contributing information to the data repository for the 2010 Maule Earthquake. All information provided shall be credited appropriately. We are interested in photographs, drawings, or sketches of buildings, building coordinates, information on soils at building sites, information on ground motion, annotations on damage level, as well as other information that may benefit our effort. The profession would gain much from your contribution.

Should you be interested in contributing to the database to benefit our profession, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. and we will provide you with a set of instructions to facilitate the data transfer.


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.

Available Products. The library of completed ATC products includes more than 100 publications on key issues in structural, earthquake, wind, and coastal engineering.  Some are available as free downloads and others can be purchased through ATC’s newly updated online store.   More…

Projects. With funding from various government agencies and the ATC Endowment Fund, ATC is actively engaged in a broad range of funded technical projects to mitigate the effects of natural and other hazards on the built environment.

Events. Periodically ATC conducts seminars, conferences, workshops, webinars, and other meetings to document and advance the state of structural engineering practice and to identify research needs.  Registration for these events can be made through the “Events” section of this website.  ATC also has the ability to provide an instructor to conduct your ATC-20 and ATC-45 in-person trainings, and information about these options is available under On Demand Training in the Product menu above.
