ATC-125 PROJECT

PROJECT OVERVIEW

Project Title: Recovery Advisories for the South Napa Earthquake

Project Status: Report Published

Client: Federal Emergency Management Agency (FEMA)

PROJECT SUMMARY

Soon after some natural disasters, the Federal Emergency Management Agency (FEMA) develops Recovery Advisories—short (5 to 10 page) documents providing guidance on how to repair or mitigate specific issues identified in a particular disaster. The FEMA Building Science Branch often works with the Joint Field Office and uses the findings from Mitigation Assessment Team reports to inform the development of FEMA Recovery Advisories.

After the August 24, 2014, magnitude 6.0 South Napa earthquake, FEMA contracted the Applied Technology Council (ATC) to develop two FEMA Recovery Advisories related to: (1) masonry fireplace chimneys, and (2) cripple walls in residential structures. Although these Recovery Advisories were developed following the 2014 South Napa earthquake, the technical content is not specific to this earthquake: the Recovery Advisories may be used to aid the recovery process after future earthquakes and for pre-earthquake hazard mitigation.

These two FEMA South Napa Earthquake Recovery Advisories are also included in the appendices of FEMA P-1024, Performance of Buildings and Nonstructural Components in the 2014 South Napa Earthquake. FEMA P-1024 provides an assessment of the performance of a select number of buildings impacted by the earthquake and corresponding recommendations to further improve mitigation.

Repair of Earthquake-Damaged Masonry Fireplace Chimneys

This FEMA Recovery Advisory recommends best practices for the reconstruction of earthquake-damaged masonry chimneys in one- or two-family dwellings to minimize risk of damage in future earthquakes. The best practices detailed in this advisory are also recommended for retrofit of masonry chimneys. The information included in the Recovery Advisory is intended to be used by homeowners to compare and contrast the various options for reconstruction and retrofit, as well as by contractors to understand details and applicable building code requirements associated with the implementation of these options. Readers should note that this Recovery Advisory does not fully detail construction requirements; a homeowner or contractor will still need to obtain a building permit to perform the work described in this advisory.

Earthquake Strengthening of Cripple Walls in Wood-Frame Dwellings

The South Napa earthquake damaged many cripple walls in residential structures, and many of the damaged cripple walls were taller than four feet. This FEMA Recovery Advisory addresses the earthquake strengthening of cripple walls and foundation anchorage in one- or two- family residential structures, supported by elevated concrete foundation systems and cripple walls not taller than approximately seven feet. In its first part, the Recovery Advisory describes the issue of earthquake strengthening of cripple walls and foundation anchorage for a typical homeowner. The second part is an accompanying Plan Set, which provides a pre-engineered retrofit solution and step-by-step instructions for use by knowledgeable contractors or skilled homeowners in customizing the work for the conditions in a specific dwelling. The contractor or homeowner must still obtain a building permit to perform the work described in this advisory.

ATC-20-1 Bhutan Field Manual

PROJECT OVERVIEW

Title: Development of Field Manual: Postearthquake Safety Evaluation of Buildings, Bhutan Edition (ATC-20-1 Bhutan)

Funding Provided By: World Bank’s Global Facility for Disaster Reduction and Recovery (GFDRR) and the Applied Technology Council Endowment Fund

Developed By: the Applied Technology Council (ATC), GeoHazards International (GHI), and the Royal Government of Bhutan’s Department of Engineering Services (DES) and Department of Disaster Management (DDM)

Status: This document was completed in January 2015

Participants: To see a list of project participants, click here.

Final Product:

This document represents adaptations to the U.S. version of the ATC-20-1 Field Manual  to account for Bhutan’s vernacular buildings, as well as Bhutan’s cultural and governmental context. During the development, a number of improvements were made to the presentation of material in the ATC-20-1 Field Manual, including a graphical format with numerous images to help engineers evaluate damaged buildings more accurately. Also, the procedures incorporate recent lessons learned during postearthquake safety evaluations following the Chile (2010) and New Zealand (2010-2011) earthquakes.

Sample pages from Chapter 6, Stone Masonry Buildings, showing the graphical format of the document. Table 6.1 is 13 pages long and presents damage conditions with photographs or illustrations.

An electronic copy of the document is not available online. To view the cover, title page, and table of contents, click here.  If you wish to purchase a hard-copy version of the document, please contact This email address is being protected from spambots. You need JavaScript enabled to view it..

An overview of the project that developed the Field Manual was presented at the 10th National Conference on Earthquake Engineering in Anchorage, Alaska in July 2015, and may be viewed here.

In accordance with the ATC-20 Methodology, forms for recording safety evaluation results for Rapid and Detailed Evaluations were developed for buildings in Bhutan. These forms are provided in A4 size in PDF format here.

After undergoing safety evaluation, buildings are posted with one of three placards: INSPECTED, RESTRICTED USE, or UNSAFE. These forms are provided in A4 size in PDF format here.

ATC-20-1 Bhutan Field Manual also presents interim procedures for advisory placarding of single-family homes. When this document was developed, Bhutan had limited resources for response and recovery. The Department of Disaster Management determined that the results of postearthquake safety evaluations should be provided as safety advisories for occupants of single-family homes. The Department is working to enhance response capacity and intends that the provisions in this appendix serve as an interim measure. The technical developers of this document, including the U.S.-Bhutan Project Engineering Panel, ATC, GeoHazards International, and Department of Engineering Services, believe that mandatory placarding, in which directives on placards are legally binding and enforceable, is essential for public safety. The technical developers strongly support efforts to move to mandatory placarding for all buildings as soon as possible. The procedures are presented in Appendix F of the document. The advisory placards for INSPECTED, RESTRICTED USE, and UNSAFE are provided in A4 size in PDF format here.

ATC-15-15:
16th U.S.-Japan-New Zealand Workshop on the
Improvement of Structural Engineering and Resiliency

PROJECT OVERVIEW

Title: 16th U.S.-Japan-New Zealand Workshop on the Improvement of Structural Engineering and Resiliency

Project Status: This Workshop was conducted on June 27-29, 2016 at the Todaiji Temple Cultural Center in Nara, Japan.

Sponsors: Applied Technology Council (ATC), the Japan Structural Consultants Association (JSCA), the New Zealand Centre of Research Excellence (QuakeCoRE), and the New Zealand Society for Earthquake Engineering

PROJECT SUMMARY

The Purpose of the Workshop was to discuss and develop policy recommendations for improved community resilience based on topics related to current state-of-practice, innovative engineering solutions, and emerging resilience technologies. A special focus of the Workshop was on post-earthquake repair and assessment of residual capacity of earthquake-damaged buildings.

This Workshop was the 16th in a series that began in 1984 and has been repeated every two or three years. Previous workshops have been held in California (San Diego and San Francisco), Hawaii (Honolulu, Kauai, Kona, Kohala Coast, and Maui), Japan (Kobe and Tokyo), and Victoria, British Columbia.  For this workshop, the program was expanded to include representation from New Zealand in addition to the United States and Japan.

Workshop Program. The Workshop Program was designed for practicing engineers, researchers, planners, policy makers, and other risk reduction specialists. It included technical presentations, panel discussions, and policy-development discussions. Technical sessions were planned around resiliency based engineering, post-earthquake repair and residual capacity, innovative structural design, technologies in underdeveloped countries, risk identification and reduction, earthquake response and recovery, and nonstructural elements.
 
Workshop Participants. The Workshop Participants included those with a background in the performance of buildings and other structures in severe earthquakes, including the effects of tsunami, and response, recovery, and reconstruction efforts following a major earthquake or tsunami.
 
Summary of Workshop Findings. The workshop was structured to include presentation and discussion. Presentations and papers can be found in the table below. Presentations provided information and opinions from experts in seven topical areas related to f structural engineering and resiliency, which were followed by discussions agreeing on conclusions and policy recommendations for improved community resilience. The Workshop Findings were summarized to present the overall conclusions from each session. The following recommendations were the agreed upon highest priority conclusions and recommendations across all sessions:
 
Session I: Resiliency Based Engineering
  • Resilience is not just an engineering problem. We need to engage with society, and create buy-in for what is needed for resilience and what that means to non-engineers.
  • We need to consider siting and land-use planning impacts on performance.
  • Damage and loss are not the same thing. Damage does not necessarily mean loss. We need to minimize loss (e.g., repair costs, downtime, injury, life loss).
  • We need to better understand the link between component-based design and system level performance.
  • Codes provide us a minimum standard. We need to evolve to promote best practices for serving society.
  • Communication is important. We need multi-language, multi-cultural sharing of information.
Session II: Post-Earthquake Repair and Residual Capacity
  • The participating organizations resolve to collaborate on the development of residual capacity guidelines.
Session III: Innovative Structural Design for Large Earthquakes
  • Holistic design principles should be considered with innovative solutions.
  • We need innovative design for construction types that represent the most common types of buildings (not just special or important structures).
Session IV: Risk Identification and Reduction
  • Seismic risk is not the only risk (e.g., tsunami, fire, multi-hazard).
  • We must not forget the basic life-safety intent of the codes.
  • We must address the risks in our existing building stock.
Session V: Earthquake Response and Recovery
  • We need to document successes so that we know where codes are working.
  • Conservatism in design and construction should be considered in a commercial context. We need to communicate the case for conservatism.
Session VI: Engineering and Technology in Developing Countries
  • We need to adapt our seismic technologies and share appropriate technologies (and processes) with developing countries.
Session VII: Resiliency of Non-Structural Elements
  • The cost-benefit ratio of nonstructural bracing needs to be considered (including consideration of downtime and design fees).
  • Structural response can impact nonstructural damage exposure. Holistic structural and nonstructural design is needed (especially for new construction).
  • For success in nonstructural implementation, we need to take advantage of the broader partnerships in the building industry: design, regulation, enforcement, and manufacture.
