Back4.1.8.15.(6)

ATTRIBUTION:

Most technical provisions of the BC Fire Code describe how the code’s objectives and functional statements are achieved. However, some provisions, like this one, do not relate directly to a code objective. The following analysis is provided to assist in understanding of the provision.

 

APPLICATION:

Design forces for the Seismic Force Resisting System when the Rd and Ro values conform to Table 4.1.8.9. and the foundation is designed in accordance with Sentence 4.1.8.16.(1).
This applies to buildings described in Sentence 1.3.3.2.(1) of Division A and to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] that are required to be designed in accordance with the requirements of Part 4.

INTENT:

To supersede the requirements of Article 4.1.8.11., which applies to the Equivalent Static Force Procedure, and of Article 4.1.8.12., which applies to the Dynamic Analysis Procedure, and limit the design forces for the elements of the Seismic Force Resisting System to the maximum values corresponding to the force for which the rocking foundation is designed.
