Plate girder, formed by welding (or occasionally bolting or riveting) plates. I-beams are commonly made of structural steel but may also be formed from aluminium or other
The dragon-beam which runs diagonally from one corner to another, and supports the corner posts above and supported by the corner posts below; The jetty beams or joists conform t floor dimensions above, but are at right angles to the jetty-plates that conform to the shorter dimensions of "roof" of the floor below. Jetty beams are mortised at 45 ...
A beam of PSL lumber installed to replace a load-bearing wall. The primary tool for structural analysis of beams is the Euler–Bernoulli beam equation. This equation accurately describes the elastic behaviour of slender beams where the cross sectional dimensions are small compared to the length of the beam.
An engineered wood joist, more commonly known as an I-joist, is a product designed to eliminate problems that occur with conventional wood joists. Invented in 1969, the I-joist is an engineered wood product that has great strength in relation to its size and weight. The biggest notable difference from dimensional lumber is that the I-joist ...
As such, a beam acts as one larger piece of lumber – thus eliminating the need to harvest larger, older trees for the same size beam. Manufactured trusses – trusses are used in home construction as a pre-fabricated replacement for roof rafters and ceiling joists (stick-framing). It is seen as an easier installation and a better solution for ...
