Section 362.2109. Empirical design of masonry.

 

(1)   Bearing on masonry . This is a department rule in addition to the requirements in IBC section 2109.1: Lintels shall be considered structural members and shall be designed in accordance with the applicable provisions of IBC chapter 16.

(2)   Jointing . These are department rules in addition to the requirements in IBC section 2109:

(a) Expansion and shrinkage. Joints commensurate with lateral stability requirements shall be installed in all exterior masonry to allow for expected growth of clay products and shrinkage of concrete products.

(b) Vertical jointing. Vertical movement joints shall be provided at a spacing in compliance with Table 362.2109.

(c) Horizontal jointing. Where supports such as shelf angles or plates are required to carry the weight of masonry above the foundation level, a pressure–relieving joint shall be provided between the structural support and any masonry that occurs below this level. The joint width shall be such as to prevent any load being transmitted from the support to any element directly below. All mortar and rigid materials shall be kept out of this joint. This type of joint shall be provided at all such supports in a concrete frame structure where clay masonry is exposed to the weather. - See PDF for table
