Glulam Roof Design

Several layers of spruce wood are glued together in the direction of the grain and processed into customised glulam elements.
Glulam roof design. In commercial design custom glulam beams can span more than 100 feet. Design values structural glued laminated timber shall provide design values for normal load duration and dry use condition 1 2 the design should specify a layup combination from ansi 117 or apa data file. The beam span length is fixed for this demo version. 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.
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. In reticulated glulam framed dome structures glulam arches span more than 500 feet. The glulam product guide form x440 describes apa trademarked glulam addresses important design considerations and includes a specification guide it also highlights some of the many applications where glulam is used in construction. Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads.
Glulam design specifications form y117. Glulam roof beams. The full version allows you to design beams of any size. See design examples 2 and 3 pages 24 25 for examples of preliminary design using glulam beam load span tables.
Glulam trusses also take many shapes including simple pitched trusses complicated scissors configurations and long span bowstring trusses with curved upper chords. These tables are provided as a guideline. It is light weight and retains its shape. Final design should include a complete analysis including bearing stresses and lateral stability.
Glued laminated timber or glulam is the beating heart of timber engineering. Our glued laminated timber offers excellent statics qualities. Appearance grade glulam shall be framing framing l. Glued laminated timber is a versatile engineered wood that is frequently specified for its strength beauty and reliability.
By using the latest 3d modelling cad packages glulam members can be modelled accurately using clash analysis of members and connections. Download the glued laminated beam design tables form s475 provide recommended preliminary design loads for two of the most common glulam.
