Building Classes
15
A
Random rubble masonry, timber or steel joist floors; tile on timber roofs
Type A are usually traditional stone masonry buildings of two or three stories which have been the dominant building type in the area for many centuries; mostly consist of a coarse, short-bedded, ill-laid rubble masonry with great thickness of mortar joints and very thcik walls. Many have had additional stories added in new materials without strengthening the supporting structure. Fir timber made up the floor joists and roof rafters, but are often replaced by concrete floors supported by steel joists and ceramic planks that are not bonded together laterally nor tied into the walls.
16
B
consist of two types of buildings; combined because performance was not significantly different: dressed stone, brick or block masonry with or without reinforced concrete floors or ring beams
Type B mostly consist of better-built older stone masonry buildings with dressed stone outer skins and well bonded corners; many are of manufactured masonry units, concrete block, brick or hollow ceramic block, and have reinforced concrete floors and eaves slabs continuous through the walls and also connected together laterally.
17
C
Reinforced concrete frame buildings
Majority of recent buildings are of Type C, reinforced concrete frame buildings; their floors and roofs commonly consist of in-situ reinforced filler slabs with ceramic plank fillers, supported on an often irregular grid of square columns; both internal and extranal infill walls often consist of double-skin hollow, loosely-bonded ceramic block; external walls are sometimes of concrete block.
