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.
The resulting flitched beam was then secured with resin and bolts, preserving appearance while providing strength. Flitch beams were used as columns in a two-story new construction. Glulam beams were used to support the second floor and the roof. This allowed the appearance of wooden columns, while providing the necessary strength.
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).
Cross hipped: The result of joining two or more hip roof sections together, forming a T or L shape for the simplest forms, or any number of more complex shapes. Satari: A Swedish variant on the monitor roof; a double hip roof with a short vertical wall usually with small windows, popular from the 17th century on formal buildings.
LVL is a type of structural composite lumber, comparable to glued laminated timber (glulam) but with a higher allowable stress. [1] A high performance more sustainable alternative to lumber, Laminated Veneer Lumber (LVL) beams, headers and columns are used in structural applications to carry heavy loads with minimum weight.

Two king post trusses linked to support a roof. Key:1: ridge beam, 2: purlins, 3: common rafters. This is an example of a "double roof" with principal rafters and common rafters. A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof.
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° into the sides of the dragon beams. They are the main constituents of the cantilever system, and determine how far the jetty projects.
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 ...
