Secondary System Anchoring in Structural Engineering

Secondary system anchoring is a critical part of modern structural engineering, especially in seismic zones. At NYA, we provide expert anchorage design for mechanical, electrical, and plumbing (MEP) systems, as well as architectural and equipment elements. These secondary components—while not part of the primary structure—must still be anchored securely to protect life and property during events like earthquakes.

What Is Secondary System Anchoring?

Secondary system anchoring refers to the securing of nonstructural elements such as piping, HVAC units, emergency lighting, and medical equipment to structural elements. For instance, a rooftop chiller or interior fire suppression system must be designed to resist both gravity and lateral forces. Therefore, we consider both seismic anchorage and wind load compliance in our anchoring designs.

Our Anchorage Design Approach

At NYA, we use a performance-based approach tailored to the project’s seismic category and risk level. Moreover, we coordinate with MEP engineers, architects, and contractors to ensure anchoring layouts are accurate, efficient, and constructible.

• Design of anchors and supports per ASCE 7, CBC, and IBC
• Evaluation of concrete or steel connections
• Anchoring suspended equipment and overhead utilities
• OSHPD and DSA-compliant anchorage for hospitals and schools
• Nonlinear analysis when needed for high-impact systems
