What is Seismic Certification?

3

•Building codes prescribe the earthquake demand that becomes a

requirement when state and local jurisdictions enforce code provisions

•Seismic certification is a validation activity ensuring nonstructural products

have greater withstand capacity compared to the prescribed demand

•Two types of certification Self-certification and 3rd party certification✓ ✓


What is Nonstructural?

4

•Building skeleton

includes:

✓ Foundation

✓ Beams

✓ Columns

✓ Walls

✓ Lateral bracing

✓ Floor slabs


What is Nonstructural?

5

•Nonstructural includes

everything contained

within the skeleton that

makes a building

function:

✓ Mechanical and

Electrical Equipment

✓ Mechanical and

Electrical Distribution

Systems

✓ Building Occupancy

How to Establish Compliance?

6

•The simple answer is to validate for a given product order that:

The Manual Process…

12

Hazard Map(USGS Website)

• Codes must have a

map to relate

location to

earthquake demand

• Could be defined in

zone boundaries or

lat/lon coordinates

Design Spectrum(ASCE 7 Seismic Loads)

• Codes must have a

building design

spectrum

• Typically

constructed based

on hazard map

parameters

Floor Spectrum(AC156 Test Spectrum)

• Assumption for

building floor

transfer function

• This is validated by

independent SMEs

• U.S. code formalized

this via AC156

Jobsite Location(Google Maps)

• Customer

application must

reference install

location

• Could be defined as

address or Zip code

Product Line Capacity Primer…


Equipment Seismic Capacity

16

● Capacity is measure of equipment’s ability to withstand earthquake loading conditions

▪ Horizontal and vertical accelerations applied through equipment anchorage tie-down points

● Capacity includes both structural integrity and active operation considerations…thus testing is mandatory

● Tri-axial testing is preferred

Possible Seismic Testing Options

19

• Test products to a worst case maximum envelope of earthquake demands

covering NA regions

• Create one certificate of conformance for each product type

• Make certificates available to commercial teams

• Product orders that require seismic are issued certificates

• Simple execution model for commercial teams

• Difficult execution model for engineering teams

Marketing Option 1



20

• Not practical to test using maximum ground motion…it’s too high!

• Most products would require costly seismic enhancements to pass test

• Not a realistic option…and no buildings are located at extreme “hot spots”

Marketing Option 1



21

• Test products to the product limits which is variable and is less than

maximum…no additional enclosure design cost needed

• Create certificates based on jobsite location on an order-by-order basis

• Make a web tool available to commercial teams

• Product orders that require seismic are issued “site-specific” certificates

via web tool

• Slightly more complex execution model for commercial teams but with

major savings for engineering teams

Marketing Option 2

✓Schneider Electric has been using site-specific certification

since 2004
