What you need to know about GE compliance with IBC-2012

 

  • GE has established consolidated IBC-2012 seismic capable product lines
  • Products were 3D shake table tested in accordance with ICC-ES-AC156
  • Products are rated to perform successfully during and after seismic activity
  • Developed for areas with stringent seismic requirements
  • Needed in essential facilities (data centers, hospitals, etc.)

 

Seismic certification and analytical work was performed by FORELL/ELSESSER ENGINEERS, INC. Registered Professional Engineer, Structural, California license #S4454 & "W. E. Gundy & Associates, Inc., Registered Professional Engineers," William E. Gundy, Registered Professional Engineer, California license #CE-26539.

Critical Power Products

 

Critical Power completed an extensive 3D shake-table test program to certify the seismic capabilities in accordance with the International Building Code (IBC-2009) and OSHPD Special Seismic Certification Preapproval (OSP) on a full range of Automatic Transfer Switch (ATS) and Paralleling Switchgear (PSG) products.

 

The GE Zenith ZTX, ZTG, ZTS and ZTE Series of transfer switches meet this Seismic standard. Included are Bypass/Isolation transfer switches. Excluded are ZTSMV, ZTSSL, and ZTGSE Series transfer switches. Energy commander two-bay cabinet Paralleling Switchgear (PSG) is included.

 

Seismic certification is frequently required in mission critical facilities applications and the GE Critical Power products are rated to perform successfully during and after seismic activity. The IBC code supersedes previous building codes (NBC, SBC, UBC).

 

What you need to know about GE compliance with IBC-2009:

 

  • GE has established IBC-2009 and OSHPD Special Seismic Certification Preapproval (OSP) seismic capable Automatic Transfer Switch (ATS) product lines
  • Products were 3D shake table tested in accordance with ICC-ES-AC156 ("Acceptance Criteria for Seismic Qualification by Shake-Table Testing of Nonstructural Components and Systems")
  • Products are rated to perform successfully during and after seismic activity
  • Developed for areas and installations with stringent seismic requirements
  • Needed in mission critical facilities (data centers, hospitals, etc.)

 

Test Criteria

lp Equipment importance factor (from 1.0 to 1.5). All GE equipment with seismic certification is qualified to an Ip level of 1.5, indicating the equipment will be fully functional during and after a seismic event.
z/h The ratio of equipment mounting height (z) to roof height (h) (From 0 to 1). Ground and roof mounted equipment, for example, would have z/h levels of 0 and 1, respectively.
Ss Mapped maximum considered earthquake response at short periods [%g]. Values are assigned based upon geographic location, probability, and severity of seismic activity; provided on maps in IBC-2009. (From 0% to 300%).
Sds Design spectral response acceleration at short periods [g]. Adjusted value based upon Ss and installation site characteristics. (From 0.0 to 2.0) Sds =2/3 * Fa * Ss (where 0.8 < Fa < 1). IBC seismic testing qualified each product line to specific Sds levels for ground- and roof-level installation. Equipment Sds levels must equal or exceed the Sds levels of the installation location.

 

 

Seismic Certification and analytical work was performed by W.E. Gundy & Associates, Inc., Registered Professional Engineers. Reports include verification test results as well as qualification to IBC-2009 and IEEE-693-2005 standards.
