Ch 8 - Masonry And Ordinary Construction Flashcards
Drawbacks
Long term deterioration of mortar joints
Labor intensive construction
Portland cement
Most common type of cement
Spalling
Expansion of excess moisture in within masonry materials causing it to break apart
Fire resistance
Varies based on masonry used and thickness of wall
Usually last part of building to fail
Basic components
Exterior load bearing masonry
Wood joists
Load bearing masonry walls
Brick or concrete block
Single wythe or multiple wythes
Wall is thickest at the bottom to handle load and maintain stability
Wythe
Single vertical column of masonry units (a single vertical brick wall layer)
Course
Horizontal layer of masonry units
Stretcher course
Bricks placed end to end
Soldier course
Bricks placed vertically end to end
Header course
Bricks placed with the end facing out
Reinforced masonry walls
Brick wythe combined with concrete wythe
Metal tie rods placed between brick and concrete wythes
Vertical steel rods in concrete wythe between brick wythes
Interior framing
Could be any number of materials
Transfers load to exterior load bearing walls
Fire cut
Angled cut made at the end of a wood joist to allow the beam to fall away freely upon failure, instead of pulling/pushing on exterior wall
Parapet walls
May be aesthetic but also may reduce fire spread from flammable roof materials to nearby buildings
