Design professionals weigh building codes for earthquake resilience strategies

In a recent meeting held by the Department of Health Care Access and Information in California, discussions centered around the Seismic Performance Category (SPC) compliance for healthcare facilities, highlighting the importance of building safety in the face of potential earthquakes. The meeting emphasized the need for hospitals and healthcare buildings to meet stringent seismic standards to ensure they remain operational during emergencies.

One of the key points raised was the distinction between older building codes and newer standards. While some facilities have undergone upgrades to meet SPC 4D standards, experts cautioned that these upgrades do not equate to the safety and reliability of new constructions. The conversation underscored that while improvements have been made, older buildings still pose risks and may not perform as well during seismic events.

The meeting also addressed the challenges of adhering to the 1980 building code, which is now over four decades old. Although this code provides a prescriptive approach to seismic safety, many consultants find it difficult to meet its requirements due to complex detailing. In contrast, the ASC 41 standard offers more flexibility and tools for engineers, making it a preferred choice for assessing existing buildings.

Participants noted that while the 1980 option remains available, it is often not feasible for many structures. Instead, ASC 41 is recommended for its practicality and effectiveness in ensuring that healthcare facilities can withstand earthquakes. The discussion highlighted the dual criteria of damage control during a design earthquake and collapse prevention during more severe seismic events, emphasizing the critical need for hospitals to be prepared for emergencies.

As California continues to face seismic risks, the outcomes of this meeting are vital for ensuring that healthcare facilities are not only compliant with safety standards but also capable of serving the community during crises. The focus on improving building safety aligns with broader goals of enhancing public health infrastructure and resilience in the face of natural disasters.
