1613.1 - Scope
Every structure, and portion thereof, including nonstructural components that are permanently attached to structures and their supports and attachments, shall be designed and constructed to resist the effects of earthquake motions in accordance with ASCE 7, excluding Chapter 14 and Appendix 11A. The seismic design category for a structure is permitted to be determined in accordance with Section 1613 or ASCE 7.
Exceptions:
1. Detached one- and two-family dwellings,
assigned to Seismic Design Category A, B or C, or located
where the mapped short-period spectral response acceleration,
SS, is less than 0.4 g.
2. The seismic-force-resisting system of
wood-frame buildings that conform to the provisions of Section 2308 are not
required to be analyzed as specified in this section.
3. Agricultural storage structures intended
only for incidental human occupancy.
4. Structures that require special
consideration of their response characteristics and environment that are not
addressed by this code or ASCE 7 and for which other regulations provide
seismic criteria, such as vehicular bridges, electrical transmission towers,
hydraulic structures, buried utility lines and their appurtenances and nuclear
reactors.
Notes
State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
