Parallam is the brand name for the product invented, developed, commercialized and patented by MacMillan Bloedel (now Weyerhaeuser). It is the world's only commercially manufactured and marketed parallel-strand lumber product.
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 ...
The following is a list of spans, either used for overhead line crossings of rivers, sea straits or valleys, as antenna or for aerial tramways. This list is incomplete ; you can help by adding missing items .
The span of the Pantheon, Rome, is not 43.3 m because there is a hole at the top of 9.1 m, so the span has been reduced with the size of the hole to 34.2 m. The span of any structure is measured in the following way: Place the largest possible imaginary horizontal circular disk under or inside the structure, barely touching any load-bearing ...
The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.
Glulam brace with plates used for connections Glulam frame of a roof structure. Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis.
Carquinez Bridge – original cantilever span built in 1927 and later twinned in 1958; a newer suspension span was built in 2003 to replace the original 1927 span, which was later demolished in 2007. Chesapeake Bay Bridge – twin suspension spans with notable visual differences in construction techniques.
l A: Span length (distance between support point and the nearest loading point of the test punch) in mm; l B: Length of the reference beam (between the loading points, symmetrically placed relative to the loading points) in mm; D L: Distance between the reference beam and the main beam (centered between the loading points) in mm
