Wood Products Flashcards
What are some advantages of manufactured wood products? (5)
- more sizes and shapes
- fewer defects
- more consistent quality
- more efficient use of wood materials
- in some cases, stronger and stiffer than solid wood members
What are the five most common manufactured wood products? (5)
- glue-laminated (glulam)
- cross-laminated timber (CLT)
- structural composite lumber
- wood I-joists
- wood-plastic components
What is glue-laminated wood?
beams made from glued, solid lumber pieces
What are some advantages of glue-laminated wood? (3)
- size: almost any desired size can be laminated
- shape: wood can be laminated into shapes such as curves and angles
- quality: can be specified and controlled in laminated members
What are the two types of end joints used in glue-laminated wood?
- finger-jointed
- scarf-jointed
What is used to increase structural capacity in FRP reinforced glulam beams?
a thin strip of fiber-reinforced plastic
What is cross-laminated timber?
solid lumber pieces laminated into structural panels
How are the layers of cross-laminated timber oriented?
each layer alternates direction
What are some advantages of cross-laminated timber? (4)
- allows-rapid on-site assembly
- used for walls, floors, and roofs
- structurally competitive with concrete structures
- used in Europe for decades; recently approved for use in the U.S.
What are some examples of structural composite lumber? (5)
- laminated strand lumber (LSL)
- oriented strand lumber (OSL)
- laminated veneer lumber (LVL)
- parallel strand lumber (PSL)
- structural finger-jointed lumber
What are laminated strand lumber and oriented strand lumber made of?
shredded wood strands
What is laminated veneer lumber made of?
thin wood veneer sheets
What is parallel strand lumber made of?
thin strips of wood veneer
What is structural finger-jointed lumber made of?
short lengths of solid lumber scrap
What is an advantage of I-joists?
can span further than solid lumber, using less raw material
