(2)P The rules given in Part 3 are consistent with those given in Part 1-1, but are more conservative in respect of the conditions and limitations of their use. (3) For those types of masonry structure or parts of structures not covered by (1), the design shall be based on Part 1-1. (4) This Part 3 applies only to those masonry structures, or parts thereof, that are described in Part 1-1 and Part 2. (5) The simplified calculation methods given in this Part 3 do not cover the design for accidental situations.
