spring mounts pass the ASHRAE 171-2017 standards.
Once the modelling and forces have been calculated, the isolator mount can be chosen. The construction material of the non-structural component.Ģ. The elevation and position of the non-structural component with respect to the structure.
The data about the seismic zone where the equipment is to be installed. To determine the horizontal force, it's important to obtain: Approximately calculate the horizontal and vertical forces acting upon the equipment during a seismic event or disaster. There are 2 fundamental parameters to effectively choose seismic/vibration-damping mounts for particular equipment:ġ. Also known as spring travel, and can be alternatively defined as the distance travelled by a spring when it is in the loaded position.Ĭomponents Of Designing A Seismic Restraint Isolator: It is an action of the spring when a force is applied or released. Spring deflection is defined as the motion of the spring due to the application or release of a given load. It prevents or minimizes the high-frequency vibration from a machine or HVAC system from being transferred to the building via spring deflection. Their main purpose is to isolate the building from the vibration coming from the machines and equipment.Ī seismic restraint is a design of the spring mount which function is to prevent non-structural elements such as machines from moving or vibrating and withstand horizontal and uplift forces during seismic events and other natural disasters.Ī spring isolator mount comprises laterally stable zinc-plated springs mounted in a sturdy steel housing. offers seismic restrained spring mount isolators for the building and construction industry.
