It is a prefabricated engineered wood panel that is made up of three to four layers of solid-sawn lumber
or composite lumber.
CLT is a prefabricated solid engineered wood product made of at least three orthogonally bonded layers of solid-sawn lumber
or structural composite lumber (SCL) that are laminated by gluing of longitudinal and transverse layers with structural adhesives to form massive panels intended for roof, floor, or wall applications (Van de Kuillen et al.
Trus Joist, A Weyerhaeuser Business, is the world's leading manufacturer and marketer of engineered lumber products--high quality alternatives to solid-sawn lumber
The development of partial composite action between sheathing panels and solid-sawn lumber
and the resulting beneficial effects on strength and stiffness have seen significant study.
Manufactured with solid-sawn lumber
or structural composite lumber and plywood or oriented strand board, engineered I-joists allow manufacturers to make the most efficient use of wood.
The increase of MOE and UTS with increasing thickness seems counter-intuitive compared to current solid-sawn lumber
The solid-sawn lumber
values were measured by plate tests and bending tests, while the SCL values were measured only by bending tests.
Glulams (glue-laminated structural timbers) are beams made from individual pieces of solid-sawn lumber
bonded together to make a single piece.
Updated EWS Data Files include: substitution of glulam beams for steel or solid-sawn lumber
, design of structural glulam timber columns, and evaluation of check size in glulam timber beams.
For years they'd seen the quality of solid-sawn lumber
Structural composite lumber (SCL) has proven to be a useful and popular alternative to solid-sawn lumber
. The use of SCLs in light frame construction has increased substantially in recent years.
