Masonry Construction Codes

Masonry construction codes supported by Touchstone.

AIR provides the following codes for masonry construction:

Note:

Touchstone applies non-engineered building damage distributions to the following construction classes regardless of occupancy class (including the industrial facility (400-series) occupancy classes: 101, 102, 103, 104, 111, 112, 113, 114, 115, 173, 174, 178, 179, 261. This applies to the AIR Earthquake Model for Japan and to the AIR Earthquake Model for Canada.


Construction Code	Category	Description
111	Masonry	Use this option when the exterior walls are constructed of masonry materials, but detailed construction information is unavailable or unknown.
112	Adobe	Adobe construction uses adobe (clay) blocks with cement or cement-clay mixture as mortar. The roof consists of a timber frame with clay tiles or, in some cases, metal roofing.
113	Rubble Stone Masonry	Rubble stone masonry consists of low-rise perimeter load-bearing walls composed of irregular stones laid as coursed or uncoursed rubble in a cement mortar bed, with floor and roof joists constructed with wood framing.
114	Unreinforced Masonry - Bearing Wall	Unreinforced masonry buildings consist of structures in which there is no steel reinforcing within a load-bearing masonry wall. Floors, roofs, and internal partitions in these bearing wall buildings are usually of wood.
115	Unreinforced Masonry - Bearing Frame	Unreinforced masonry is used for infill walls of buildings with a bearing frame. In this structure type, the masonry is intended to be used not to support gravity loads, but to assist with lateral loads.
116	Reinforced Masonry	Reinforced masonry construction consists of load bearing walls of reinforced brick or concrete-block masonry. Floor and roof joists constructed with wood framing are common.
117	Reinforced Masonry Shear Wall (with MRF)	Reinforced masonry construction consists of load-bearing walls of reinforced brick or concrete-block masonry. Reinforced masonry buildings with "Moment Resisting Frames" carry lateral loads by bending. "Shear Walls" are continuous reinforced brick or reinforced hollow concrete block walls extending from the foundation to the roof and can be exterior walls or interior walls.
118	Reinforced Masonry Shear Wall (without MRF)	Reinforced masonry construction consists of load-bearing walls of reinforced brick or concrete-block masonry. "Shear Walls" are continuous reinforced brick or reinforced hollow concrete block walls extending from the foundation to the roof and can be exterior walls or interior walls.
119	Joisted Masonry	Masonry exterior walls with roof of combustible materials on non-combustible supports.
120	Confined Masonry	Confined masonry is a construction system in which plain masonry walls are confined on all four sides by reinforced concrete or reinforced masonry members. The walls themselves, however, carry all the gravity and lateral loads. Currently supported for locations in Australia, the Caribbean, Central America, China, Mexico, New Zealand, South America, South Korea, and Taiwan, for some locations in Europe, including Central Europe.
121	Cavity Double Brick	An unreinforced masonry construction type composed of two layers of bricks, common in many cities in Australia. Currently supported only for locations in Australia and New Zealand.
