8.4.13 Component Force Levels Based on Ground Motion Parameters
For 8.4(b)(2), the component force level shall be the greater of that dictated by either of the following:
(a) the applicable building code's nonstructural component requirements
When the applicable building code does not reference component vertical force levels, the appropriate seismic zone vertical force level shall be used when a vertical force level is specified.
|Zone(s)||Affected Peak Velocity Acceleration, Av|
|0 and 1||Av < 0.10|
|2||0.10 ≤ Av < 0.20|
|3 and 4||0.20 ≤ Av|
|Zone(s)||Velocity-Related Seismic Zone, Zv|
|2||2 ≤ Zv < 4|
|≥3||Zv ≥ 4|
NOTE: For Zv values, see "Design Data for Selected Locations in Canada," in NBCC-1995, Appendix C.
