Special Seismic Certification

ICC-ES AC156

The most common testing procedure used for IBC and OSHPD applications is the International Code Council Evaluation Services Acceptance Criteria 156 (ICC-ES AC156).

This criteria specifies a specific input motion to which nonstructural components should be subjected.

Input motions are required to be 30 seconds in length with a stationary input motion over a broad range of frequencies. This input motion requirement is derived based on ASCE design provisions. Required response spectrum shape is derived based on building code provisions

Shake table testing can be performed on a range of table types including uni-axial, bi-axial and tri-axial.
