Six months since the South Napa earthquake, this symposium will address the topic of nonstructural protection and some of the key design and engineering issues identified in the earthquake’s aftermath.

Our expert panel includes Janiele Maffei, S.E. of the California Earthquake Authority who was on the scene in the immediate aftermath of the earthquake, Estructure’s Maryann Phipps, S.E. with over 30 years’ experience in designing and renovating buildings for seismic resistance and Roger Parra, S.E. of Degenkolb who has been working with wineries in Napa since the earthquake six months ago.

Our presenters will share with us some of the stories, key outcomes and lessons learned ‘post-Napa’ in addition to shedding light on code requirements and retrofits. Topics covered will include:

  • Residential damage in Napa / What to do about chimneys;
  • Residential Seismic retrofit and why it works;
  • Nonstructural damage to the wine industry: stacked wine barrels and stainless steel tanks;
  • Cladding damage to modern buildings;
  • Damage to contents and equipment in the Napa earthquake;
  • What causes damage to nonstructural components;
  • Code requirements for the seismic protection of nonstructural components.


Janiele MaffeiJaniele Maffei, S.E., California Earthquake AuthorityJaniele is Chief Mitigation Officer of the California Earthquake Authority in Sacramento, California. She is a graduate of UC Berkeley, where she obtained her AB degree in architecture and an MS in civil engineering. Maffei is a registered structural engineer who has worked in the earthquake engineering industry for over 30 years. Her experience includes the design of new building structures and seismic strengthening of existing structures. She designed, launched and is now operating the Earthquake Brace + Program for the CEA, which provides resources and knowledge to homeowners trying to retrofit their wood-frame homes.

maryann phippsMaryann Phipps, S.E., EstructureMaryann is a Structural Engineer with over 30 years of experience evaluating, designing and renovating buildings for seismic resistance. Her hands-on experience designing hospitals for post-earthquake functionality has helped make Maryann a recognized expert in the field. She is President of Estructure, a structural engineering firm in Oakland specializing in health care and laboratory renovations, and recognized nationally for its expertise designing seismic protection for nonstructural components.

Roger ParraRoger Parra, S.E., Degenkolb. Roger’s experience includes design of new structures and seismic strengthening of existing structures. He also has strong experience in seismic analysis and seismic evaluations of existing structures. Roger has an extensive portfolio in highly specialized facilities such as manufacturing sites and laboratories. He has worked at length implementing the seismic upgrade program for technology sector clients.
Learning Objectives

In this presentation, attendees will learn about:

1. Post-earthquake residential damage and damage to nonstructural components.
2. Residential seismic retrofit and why it works.
3. Nonstructural damage to the Napa wine industry, damage to contents and equipment and cladding damage to modern buildings.
4. What causes damage to nonstructural components and code requirements for seismic protection.
