Terms in this set (43)
- flow of heat
- air and water vapor through enclosure
- movement of building and parts
- water leakage
- aging and deterioration of material
What are some primary building performance concerns that are inescapable?
current effort to curtail ill effects practices are maturing.
aka common sense, they are used in responsible selection of materials and products within the general industry of building.
extends from materials extraction through leaving the manufacturer. Ignores delivery to construction site, installation, use, maintenance, and end of life disposition.
- IGNORES DURABILITY
classification of building elements by functional groups, such as: substructure, shell, interiors, services.
a broadly flexible system for organizing construction information according to any number of schemes.
Owner team- owner, financer, user group
Design Team- architects, engineers, and other consultants
Construction team- general contractor, subcontractors, suppliers.
What are the three major parties of construction services?
the only major structural material that is organic in origin, growing naturally in forest with most manufacturing work done for us via the sun.
Anisotropic (different qualities in different directions)
Wood is ______________ (...)
(low tech) wood is: structure, insulation, and interior/exterior finish. Inefficient construction.
Engineered wood or "heavy timber", more closest resembles the internal strength- "tree like", resulting in a more efficient construction.
White pine series
catalogue of surviving colonial works of architecture through measured drawings and photographs, help with cultural durability along with best practices.
outermost protective layer
thin layer: source of new cells outward and in
living cells that store and transport nutrients
dead cells that contribute to structural strength
the essential or central part (innermost)
Annual Growth rings
result from differences in rate of tree growth and density of cells, from spring to summer.
tubular cells that run the long axes of the tree
has water favoring rapid growth- therefore larger and less dense/weaker.
What types of woods are these?
Beech, Oak, Ash, and teak are all types of ________________.
coniferous trees (green all year round)
Softwoods come from what kind of trees?
deciduous tress (looses leaves in the winter)
What type of trees do hardwoods come from?
growth rings roughly parallel to wider face of board.
growth rings close to perpendicular to wider face of board
angle of grain falls between perfectly sawn and plain sawn.
weight of water in wood
thin sheets sliced from logs
- used in laminated panels
Glue-Laminated Wood (GluLam)
beams made from glued, solid lumber pieces
Cross-Laminated Timber (ClT)
Solid lumber pieces laminated structural panels
- lumber pieces alternate direction in each layer
- used for walls, floors, and roofs
- structurally competitive with concrete structures.
Structural Composite Lumber
substitutes for solid lumber, made from wood veneers or fiber strands and glue.
face veneers bonded to solid core
glued particles, smaller than OSB strands but larger than fiberboard particles.
4' x 8' 5/16" - 1 1/8" thick
- sheathing on framed walls and roofs, and subflooring over floor framing.
What is the standard size for structural wood panels and what are they used for?
C and D faces, with exterior glue; for exterior sheathing
C-D plugged flooring underlayment
C-plugged face provides an especially smooth surface beneath carpet or resilient flooring materials.
fire- retardent treated wood
chemical salts pressure impregnated into woods to reduce its combustibility.
chemicals pressure impregnated into wood to protect from decay and insect attack.
mainly for structural connections in heavy timber framing and in wood framing for fastening ledgers, beams and other heavy applications.
What type of framing is this?
a wooden framing system made of matched pairs of large curved timbers that are like slices of trees, forming a pointed arch where they meet at the top
a structural building frame strengthened against lateral forces with diagonal members
