Glulam Roof Section

Discussed in the preceding section.

Glulam roof section.

The tables include values for section properties and capacities and allowable loads for simple span and cantilevered beams. Its thermal properties help prevent cold bridging. Reviewing the examples with these principles in mind will enable the designer to more easily detail proper connections. The reference moisture content is 12.

Glulam connection details. The material is made up of several layers of structural timber that have been bonded together using adhesives in order to form a bigger potentially enormous piece of wood. Glulam can generally be used for the interior and the exterior. Tolerances and the natural shrinking and swelling behaviour or timber may result in dimensional deviation of the cross section.

Covered ceilings and roof beams. Other common engineered wood products include plywood oriented strandboard osb and laminated veneer lumber lvl. A glue laminated timber is an engineered wood product meaning it is made from wood but is machined and assembled to precise specifications to create a predictable dimensionally stable building material. Glulam allows a high degree of prefabrication and long structural spans where necessary but is equally effective for shorter spans.

Glulam beams laid on their flat and used as floor or roof panels are known as glt panels see glue laminated timber panels. These tables are provided as a guideline. Glued laminated timber is a versatile engineered wood that is frequently specified for its strength beauty and reliability. Aitc capacity tables provide the uniformly distributed load that a glued laminated timber beam can support based on beam size span and material properties.

The glulam production process uses adhesive that complies with ss en 301 both for the finger jointing of individual laminates and to bond the laminates. While the details in this technical note address serviceability concerns associated with glulam connection detailing. The dimensional tolerances for glulam are regulated by en 14080. Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads.

The glued laminated beam design tables form s475 provide recommended preliminary design loads for two of the most common glulam beam applications. Glulam roof beams if the proposed design of your roof is not achievable using a conventional truss design then sydenhams can incorporate glulam laminated beams to provide support intermediately or as a design statement the beams can be left exposed to provide maximum impact.
