Brittle to Resilient
Prepare Your Building for Upcoming Seismic Ordinances
Non-ductile concrete ordinances are local regulations designed to protect building owners by addressing the risks associated with older concrete structures. Buildings constructed before modern seismic codes (typically before the 1980s) often lack the flexibility to withstand earthquakes, making them prone to catastrophic failure. By taking proactive steps to retrofit your building now, you can ensure its resilience, safeguard occupants, and comply with evolving safety standards, all while protecting your investment.
How We Can Assist Building Owners
Forell Elsesser is an industry leader with extensive experience in seismic retrofits, specifically addressing non-ductile concrete buildings. We develop solutions that streamline the retrofitting process. Our combined team offers cutting-edge analysis and advanced construction expertise to ensure your building meets modern safety standards. Non-ductile concrete buildings lack the steel reinforcement necessary to withstand seismic events, and our solutions are designed to fortify these structures, safeguarding your investment and enhancing occupant safety.

Non-Ductile Concrete Ordinance Steps
1 – Identification and Inventory
Cities often first require the identification of non-ductile concrete buildings. Building owners may need to have their structures evaluated by engineers to determine if they fall into this category.
2 – Mandatory Retrofitting
Once identified, these buildings may be subject to mandatory seismic retrofitting. This involves reinforcing the structure to improve its ability to withstand seismic forces, which can be a costly and complex process.
3 – Compliance Timeline
Ordinances typically provide a timeline for compliance, giving building owners a set number of years to complete the required retrofitting. This timeline may vary based on the type of building, its occupancy, and its risk profile.
4 – Benefits to Early Compliance
In some cities, there’s benefits to complying early and addressing the issues before mandatory requirements take hold.
5 – Penalties for Non-Compliance
Non-compliance with these ordinances can result in fines, restrictions on building use, or even orders to vacate unsafe buildings.
Where are we today with non-ductile concrete ordinances?
Los Angeles Ordinance
In 2015, Los Angeles passed a non-ductile concrete ordinance that required around 1,500 buildings to be retrofitted. Owners were given a time-line of up to 25 years to complete the retrofit.
San Francisco Ordinance
San Francisco issued an executive directive order planning for implementation of ordinances in the next few years. It is considering similar ordinances to LA targeting non-ductile concrete buildings with efforts focusing on identifying vulnerable structures and enforcing retrofitting requirements.
These ordinances are crucial for improving public safety in earthquake-prone areas and reducing the potential for building collapses during earthquakes.
Tailored Seismic Retrofits: Strengthening Buildings, Securing Investments
Customized Retrofit Strategies for Seismic Resilience
Every non-ductile concrete building is unique and retrofit strategies can vary based on overall building size, number of stories, and level of seismic deficiency. The best retrofit strategies are ones that are tailored to the specific need. A retrofit could be minor where only local strengthening of individual deficient components by using fiber wrapping. Other retrofit strategies include adding “ductile” concrete walls to the interior or exterior of the building to strengthen or stiffen the building. Working with us, we can determine a retrofit strategy that works for you and your budget.
Helping Building Owners Navigate Seismic Compliance with Confidence
As experienced builders and structural engineers, we can help building owners navigate the retrofit ordinance requirements and develop options to comply. We have decades of experience performing seismic evaluations and retrofits for all building types. Our engineering team is actively involved in research on Non-Ductile Concrete buildings and are involved in helping San Francisco identify initial steps.
We are experts in nonlinear analysis, which may be used to provide a more efficient and cost-effective solution than a typical analysis, helping clients develop solutions through constant interaction and open dialogue. With our experience we can help owners navigate the path to transitioning a building from a brittle non-ductile concrete one to a more seismically resilient structure.
