Living on the West Coast, we are fully aware of the earthquake hazard in our backyards. Please join the Structural Engineers Association of Northern California (SEAONC) and their distinguished speakers to learn about ATC-143, Earthquake Damage Assessment and Repair Guidelines for Residential Wood-Frame Buildings, and case studies of both repair and retrofit.
Part 1: Thursday, October 15th from 12:00 - 2:00 PM Pacific
ATC-143: Earthquake Damage Assessment and Repair Guidelines for Residential Wood-Frame Buildings
Speakers: Morgan Griffith - Exponent, Justin Moresco - Applied Technology Council
Past earthquakes in California have demonstrated the need for more efficiency, consistency, and reliability in the assessment and repair of earthquake damage to residential wood-frame buildings. In response to this need, the California Earthquake Authority (CEA) funded the Applied Technology Council (ATC) to develop guidelines for the on-site identification and documentation of earthquake damage to residential wood-frame buildings and for the preparation of repair recommendations.The guidelines, which were published earlier this year, provide guidance related to the repair of both earthquake-induced structural damage and permanent ground deformation, making them comprehensive and multi-disciplinary in scope. The guidelines also include information to identify and assess possible damage to concealed structural elements, to help limit and focus destructive investigations, leading to more economical repair strategies and reducing disruption to occupants. This presentation will provide an overview of the guidelines, with an emphasis on the assessment and repair of structural damage. The guidelines can be downloaded for free from the ATC website.
Part 2: Wednesday, October 21st from 12:00 - 2:00 PM Pacific
Retrofit of Bakar BioEnginuity Hub at Old Berkeley Art Museum
Speaker: Masume Dana – Forell/Elsesser Engineers
The building formerly known as the Berkeley Art Museum (BAM), designed by Mario Ciampi and opened in 1971, is architecturally significant reinforced concrete building listed on the National Register of Historic Places and designated as a Historic Landmark by the City of Berkeley. As a successful adaptive reuse, the transformation of this landmark museum building into biosciences incubator and research labs is desirable from both a historical and sustainability perspective. The challenges of the project include incorporating an effective seismic retrofit into a very complicated non-orthogonal three-dimensional space, preserving the historic exposed concrete structure as much as possible, replacement of almost all M/E/P/S systems, roofing and skylights, and upgrades to accessibility. ASCE 41 standard Nonlinear Dynamic Procedure was used for the seismic evaluation of the existing structure and the retrofit design including the effects of the deep foundations.
Repair and Retrofit of the Historic Trefethen Winery Building
Speakers: Marianne Wilson & Brett Shields - ZFA
The Historic Trefethen Winery Building was constructed originally in 1886 and is the only surviving 3-story heavy timber wood framed winery building still being used as originally intended within the State of California. The wooden structure was famously and dramatically damaged to within a whisper of collapse during the August 2014 South Napa Earthquake. This presentation chronicles the history of the building and the specific and special steps toward both structural repair and retrofit which occurred over the course of the following 18 months.
