Seismic Brackets: Essential Guardians of Building Safety

In earthquake-prone areas, building safety is a top priority. Within structural and piping systems, seismic brackets play a critical role. They not only help maintain the stability of buildings during earthquakes but also minimize damage and protect people. This article will explain what seismic brackets are, their functions, types, and key considerations for selection.

What Are Seismic Brackets?

Seismic brackets, also known as seismic supports, are support systems installed on building pipes, equipment, or structures to maintain stability during earthquakes. Simply put, they act as an internal “safety net” for a building, preventing pipes and equipment from shaking, falling, or being damaged during seismic events.

Typically made of steel, seismic brackets are designed for high strength and flexibility, following national or industry standards to ensure reliability.

Key Functions of Seismic Brackets

1. Protect Building Pipes and Systems
   During an earthquake, unrestrained water pipes, gas lines, and cables may fall or rupture, causing secondary accidents. Seismic brackets secure these systems and reduce the risk of damage.

2. Ensure Personnel Safety
   Falling pipes or equipment can injure or even kill people. Seismic brackets prevent heavy objects from falling, safeguarding workers and building occupants.

3. Reduce Structural Damage
   During strong earthquakes, seismic brackets absorb part of the seismic energy, reducing stress on the building’s main structure and lowering the likelihood of structural failure.

4. Facilitate Maintenance and Inspection
   Properly designed seismic brackets leave enough space for inspection and repair of pipelines, making maintenance easier and safer.

Types of Seismic Brackets

Seismic brackets can be categorized by their application and structural type:

1. Pipe Seismic Brackets
   Used to secure plumbing, gas, and fire protection pipes. Usually steel-based, they can be fixed supports or hangers.

2. Duct Seismic Brackets
   Used for HVAC ducts, these brackets must support weight while controlling vibrations.

3. Equipment Seismic Brackets
   Designed for heavy machinery like pumps, boilers, and air conditioning units. These brackets need to bear both weight and seismic forces.

4. Cable Tray Seismic Brackets
   Ensure electrical systems remain intact during an earthquake. Can be installed as hangers or fixed supports to prevent falling or short circuits.

Design and Selection Considerations

When designing or selecting seismic brackets for a project, consider the following:

1. Seismic Intensity and Codes
   Different regions have different earthquake intensities. Design must follow national seismic design codes (e.g., GB50011 in China) and related industry standards.

2. Weight of Pipes or Equipment
   The material, size, and spacing of brackets should be calculated according to the weight and length of the supported system to ensure sufficient load capacity.

3. Installation Environment
   Indoor or outdoor conditions, corrosion resistance, and how brackets are connected to the structure all influence design choices.

4. Vibration and Shock Absorption
   For sensitive equipment or pipes, consider using vibration isolators or flexible connections to further reduce earthquake impact.

Conclusion

Seismic brackets are an indispensable part of a building’s safety system. They protect pipes and equipment while ensuring overall building stability and personnel safety. By carefully following design codes and proper installation practices, seismic brackets significantly reduce the risks associated with earthquakes.

With increasing awareness of earthquake safety and improved standards, the use of seismic brackets is becoming more widespread, offering a safer and more secure environment for everyone.
