Seismic Hangers

Seismic hangers are a type of support system used in buildings to secure non-structural elements such as pipes, ducts, and electrical conduits during seismic events. They are designed to allow these systems to move without causing damage or disconnection, thus maintaining the integrity of the building’s mechanical, electrical, and plumbing (MEP) systems during and after an earthquake.

Seismic hangers are typically made of robust materials like steel and are engineered to withstand the forces generated during an earthquake. They are designed to accommodate both vertical and lateral movement, and some models also include features to limit the movement of the supported systems to prevent them from hitting other components or structures.

The use of seismic hangers is particularly important in regions prone to earthquakes, where they are often a requirement under local building codes. They are an essential part of a building’s seismic bracing system, which also includes other components like braces, struts, and anchors.

When selecting and installing seismic hangers, it’s important to consider factors such as the weight and size of the supported systems, the expected seismic forces, and the requirements of the local building codes. Proper installation is crucial to ensure the effectiveness of the hangers in protecting the building’s MEP systems during a seismic event.
