The beams are continuously formed, so the length of the beam is limited only to the maximum length that can be handled and transported. Typical widths are 3 + 1 ⁄ 2, 5 + 1 ⁄ 4 or 7 inches (89, 133 or 178 mm); typical depths are 9 + 1 ⁄ 2, 11 + 7 ⁄ 8, 14, 16 and 18 inches (240, 300, 360, 410 and 460 mm). Typically the beams are made to a ...
In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...
Re-sawing is the splitting of 1-to-12-inch (25–305 mm) hardwood or softwood lumber into two or more thinner pieces of full-length boards. For example, splitting a 10-foot-long (3.0 m) 2×4 (1 + 1 ⁄ 2 by 3 + 1 ⁄ 2 in or 38 by 89 mm) into two 1×4s (3 ⁄ 4 by 3 + 1 ⁄ 2 in or 19 by 89 mm) of the same length is considered re-sawing.
In 1971 "Micro=Lam LVL" was introduced. "Micro=Lam LVL" consisted of laminated veneer lumber billets 4 feet (1.2 m) wide, 3 + 1 ⁄ 2 inches (89 mm) thick, and 80 feet (24 m) long. Troutner proved the structural capabilities of his Micro=Lam product by building a house in Hagerman, Idaho, using beams made of Micro=Lam.
The roof includes 2,400 cubic metres of Douglas fir lamstock lumber in glulam beams. A total of 34 yellow cedar glulam posts support the overhangs where the roof extends beyond the walls. [21] Anaheim Ice rink in Anaheim, California was built in 1995 by Disney Development Company and architect Frank Gehry using large double-curved yellow pine ...

Jetty beams are mortised at 45 ...
The dome is 143 feet (44 m) tall, has a diameter of 536 feet (163 m), covers an area of 5.1 acres (21,000 m 2) and has a volume of 16,135,907 cubic feet. It is a geodesic dome constructed with 781 Douglas fir beams and 108.5 miles (174.6 km) of fir decking and is designed to support snow up to 60 pounds per square foot (2.9 kPa) and withstand ...
Preferred species for linear structural members are softwoods such as spruce, pine and fir. Light frame material dimensions range from 38 by 89 mm (1.5 by 3.5 in); i.e., a Dimensional number two-by-four to 5 cm by 30 cm (two-by-twelve inches) at the cross-section, and lengths ranging from 2.5 metres (8.2 ft) for walls to 7 metres (23 ft) or ...
