Where is seismic bracing required?
Conduits, including HVAC ductwork, piping, and electrical conduits and raceways, may also require seismic bracing. ASCE 7 says that: HVAC ductwork needs bracing when the duct has a cross-section 6 ft. or larger or when it weighs more than 17 pounds per linear foot, or when it has an Ip=1.5.
What is seismic bracing?
Seismic Bracing & Force Protection. We offer a pre-engineered, time-saving solution which braces and secures non-structural equipment within a building to minimize damage from earthquakes or seismic events.
What are seismic restraints?
Seismic restraint is the positive attachment of components to the building structure to resist primarily horizontal forces due to an earthquake.
Why is seismic bracing used?
We offer a pre-engineered, time-saving solution which braces and secures non-structural equipment within a building to minimise damage from earthquakes or seismic events.
What is transverse bracing?
n (Anatomy) either of the projections that arise from either side of a vertebra and provide articulation for the ribs. transverse wave. n a wave, such as an electromagnetic wave, that is propagated in a direction perpendicular to the direction of displacement of the transmitting field or medium.
What is the purpose of seismic restrainer?
This site presents restraint systems which serve to limit the movement of equipment and to keep the equipment captive during a seismic event. Proper utilization of these systems can reduce the threat to life and minimize long-term costs due to equipment damage and associated loss of service.
What is seismic importance factor?
The Importance Factor is a multiplier that increases or decreases the base design loads. Typically, the base design loads are outlined by the code as a 2% annual probability of exceedence (2% in 50 years for seismic loads).
What is longitudinal bracing?
extending lengthwise of the structure, or parallel to its center line.
What is the longitudinal bracing?
