ISAT Seismic Bracing is a global provider of engineering services, consulting services and restraint system components for nonstructural seismic bracing. This course provides guidance on attaching mechanical equipment to a building to minimize earthquake damage. Australian/Harvard Citation . It must be so, as the failure or shutdown of some of the equipment might actually result in a nuclear catastrophic. The New Zealand Building Code clause B1 . Seismic Restraints for Mechanical Equipment Ezekiel Enterprises, LLC 12. Such systems encompass open gen-sets, enclosures, sub-base fuel tanks, remote radiators, automatic transfer switches and switchgear, batteries and battery racks, battery chargers, and day tanks. The damage is likely to cause ongoing lost productivity. Seismic restraint is thought to apply to the box only — what is inside is assumed to be fine. Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty-five (25) questions to earn 5 PDH credits. Many examples of attachments are presented, including anchors and seismic restraints. The design of seismic restraints of non-structural components to resist seismic load shall be based on Seismic Design parameters indicated below in accordance with VA H-18-8 in conjunction with ASCE 7// and ASCE 41//, as specified in H-18-8 Section 4.0, for existing building retrofit projects. Restraint Systems for Suspended & Supported Electrical Equipment. The Seismic Restraint for Mechanical Equipment 6 hour PDH online course is a part of the Structural category courses. Helpful Rules for Restraining Pipe and Duct . Ensure egress routes remain unobstructed. Many attachment examples are presented, including anchors and the use of special devices called seismic restraint devices. Article 4.1.8.17. Failed attachments to a chiller after the 1994 Northridge Earthquake. TITAN Modular Seismic and Wind Restraint Vibration Isolator. SEISMIC PROCESS GUIDE FOR MECHANICAL SERVICES SUBCONTRACTORS 3 3.1 Building services seismic … Seismic restraint devices include vibration isolation systems, cable or strut suspension systems, roof attachment … Zone I will not require seismic restraint of electrical equipment unless the building is required to be fully functional for post-disaster use. QuakeLoc™ is proudly made in the USA. The point at which the Equipment is connected to the building structure. The guide used in this course shows engineers and equipment installers how to attach electrical equipment to a building to minimize earthquake damage. The thinking is that, during shipment, equipment experiences acceleration forces greater than those experienced during an earthquake; if equipment survives shipment, then, it is likely to survive an earthquake. Seismic horizontal force factor Zp = ZICpWp . equipment during and after a seismic event by ensuring business continuity and continued operation of critical infrastructure and services. TITAN is recommended for equipment mounted on a structural frame or concrete inertia base where the … Many attachment examples are presented, including anchors and the use of special devices called seismic restraint devices. INTRODUCTION This guide shows equipment installers how to attach electrical equipment to a building to minimize earthquake damage. In order for hospitals to properly service the needs of the public after a seismic event, fully functioning equipment is essential. This should be verified by a trained professional, such as a licensed structural engineer of record. Chapter 17, Sec. Chillers Be sure to refer to construction drawings and specifications, seismic restraint submittals, and manufacturer’s instructions. Seismic bracing electrical systems: Considerations for heavy equipment. Consider these recent events: • The January 13 earthquake off the coast of El Salvador was a magnitude of 7.6. Step 1: Identify equipment Figure 24: Centrifugal chiller Figure 25: Chiller with screw (water-cooled). Zones II through IV may or may not requireseismic restraint depending on soil conditions and building importance. electrical, and plumbing equipment) and their supports and attachments that are permanently attached to a structure must be designed and constructed to resist the effects of the earthquake motions in accordance with governing Building Codes. ASCE 7-16 section 13.1.4 exemptions that apply at SLAC are the following. electrical cable trays, and suspended equipment. Nonstructural components may include hospital piping, electrical conduit, cable trays, and air handling ducts. Elements of Structures, Non-Structural Components and Equipment of the OBC outlines which compressors (air-cooled). a fire may break out due to electrical equipment . shorting and components may collapse onto people causing injury or block exit routes. Independent support of light fixtures, diffusers, cable trays, electrical conduit, and other ceiling appurtenances must be offered. Member ASHRAE ost areas of the world will be subjected to a future seismic input. Flooding may result from ruptured pipework, a fire may break out due to electrical equipment shorting and components may collapse onto people causing injury or block exit routes. Refer to ASCE 7-16, Chapter 13, for more information. Installing Seismic Restraints for Electrical Equipment (FEMA 413) This guide, produced by the Vibration Isolation and Seismic Control Manufacturers Association (VISCMA) for FEMA, provides equipment installers with information on how to attach electrical equipment to buildings to minimize earthquake damage.
