At the time of prestress, the compressive strength of the masonry tm equal or exceed f'[ mi ] which shall be less than or equal to f'[ m ]. A wall built of a combination of two or more masonry units bonded together, one forming the backup and the other forming the facing elements.


The units shall be of whole, sound materials and free from cracks and other defects that will interfere with proper laying or use. Load-bearing masonry structures shall be reinforced to obtain a continuous system of vertical and horizontal ties. The measured dimension of a masonry unit or element. The surfaces of units intended to be in contact with mortar shall be treated with a polyvinyl butyral coating or latex-based paint.

Corbeling of masonry units shall not leave unit cores exposed to the inside of the smoke chamber.

Masonry chimneys are permitted to be constructed as acci of the masonry walls or concrete walls of the building. The exterior air intake shall not be located within the garage, attic, basement or crawl space of the dwelling nor shall the air intake be located at an elevation higher than the firebox.

Since the Code is written as a legal document and the Specification as a master specification required by the Code, the two commentaries present background details, committee considerations, and research data used to develop the Code and Specification. The net free area of the arrestor shall not be less than four times the net free area of the outlet of the chimney flue it serves. Mechanical splices shall be classified as Type 1 or 2 according to Section The outlet shall be closable and designed to prevent burning material from dropping into concealed combustible spaces.

Maximum compressive force resisted per unit of net cross-sectional area of masonry, determined by the testing of masonry prisms or a function of individual masonry units, mortar and grout. A minimum clearance of 4 inches mm shall be provided between the exterior surfaces of a concrete or masonry chimney for medium-heat appliances and combustible material.

No salt or other chemicals for the purpose of lowering the freezing temperature of water shall be permitted in the mortar mix. Masonry walls that are not part of the lateral force resisting system shall be isolated from the structure so that the ascee and lateral forces are not imparted to these elements. All welding shall conform to AWS D1.


Masonry fireboxes shall be constructed of solid masonry units, hollow masonry units grouted solid, stone or concrete. An existing masonry wall may be used in the alteration or extension of a building provided that it meets the requirements of this code. Load-bearing masonry structures shall be reinforced to meet all of the asde of this section.
