Glulam Roof Design

Aitc capacity tables provide the uniformly distributed load that a glued laminated timber beam can support based on beam size span and material properties.

Glulam roof design.

Glulam roof beams. Final design should include a complete analysis including bearing stresses and lateral stability. Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads. By using the latest 3d modelling cad packages glulam members can be modelled accurately using clash analysis of members and connections.

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. Detailed design services include early design advice and consulting conceptual sketches 2d general arrangements 3d structural detailing and full 3d timber frame structural design. 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. Our glued laminated timber offers excellent statics qualities.

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. 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. These tables are provided as a guideline.

It is light weight and retains its shape. The beam span length is fixed for this demo version. Glued laminated timber or glulam is the beating heart of timber engineering. Download the glued laminated beam design tables form s475 provide recommended preliminary design loads for two of the most common glulam.

In commercial design custom glulam beams can span more than 100 feet. Glulam trusses also take many shapes including simple pitched trusses complicated scissors configurations and long span bowstring trusses with curved upper chords. In reticulated glulam framed dome structures glulam arches span more than 500 feet. See design examples 2 and 3 pages 24 25 for examples of preliminary design using glulam beam load span tables.

Allowable loads for cantilevered glulam roof beams tables 5 6 11 and 12 are for preliminary design of cantilevered roof beams. 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.
