Seismic Zones Equipment Needs

Building a structure that will withstand the forces of nature is important. Some issues are overlooked when designing and building a structure to be seismic proof. The owner must do the research and here is some of that research:

...Not only structural member must withstand the impact of earthquake but also the owner should consider seismic zones equipment needs for the building. Seismic zones equipment needs should not be overlooked, since impact of earthquake can create numerous hazard situations that can injury and even kill occupants before and after the earthquake wave. For example, if there is a fuel tank of some sort as part of the design in or around the building, the entire system must be seismically certified.

Sample HVAC System
In the event of an earthquake when power source could be non operational, emergency power systems must be in place, especially for those owners that critically need it; for example, in health-care settings special code-compliant backup power system must be in place.

HVAC System
As part of seismic zones equipment needs, it is required that lighting fixtures that are lay-in tile ceiling system must be independently supported directly from the structure and be supported by building's support ceiling grid system. The system must be sway-braced from at least two points of connection.
HVAC Ducts
A HVAC system is another concern in seismic zones equipment needs. Proper bracing of round duct with diameter of 28 in and larger must be made. When duct work is unbraced, it must be installed with at least 6 in of clearance to ceiling-hanger wires. Proper Anchor bolts must be used to support equipment to prevent a pullout from earthquake effect. Fans, pumps, and a like, must have housing to resist lateral load forces from an earthquake.

The earthquake valve

Installation of seismic gas valves that automatically close the gas flow is an important consideration in seismic zones equipment needs. When such valves are not installed, the possibility of fire break out is quite high...
