Curved Glulam Beams Design

Glulam trusses add design options for long spans glulam trusses also take many shapes including simple pitched trusses complicated scissor configurations and long span bowstring trusses with curved upper chords.

Curved glulam beams design.

Curved beams and custom fabrication is available. Curved and arched glulams calvert co inc. The flexibility of glulam beams allows for the designer s creative imagination to be realised. Glulam beams that curve in plan use plies that are oriented vertically therefore the finished height of the beam is based on standard glulam widths.

Aitc pitched and tapered curved beam tables. Glulam beams are readily produced in curved shapes and are available in a range of species and appearance characteristics to meet varied end use requirements. Boise glulam is a strong cost effective wood beam solution which can be used as beams or columns in a multitude of building design applications. The grain of the laminations runs parallel with the length of the member.

Products work well in single or multi family residential as well as light commercial projects. Due to the geometric shape and the manufacturing process of a curved glued laminated timber it is necessary to perform separate checks during the design. The tightness of the radius will determine the thickness of the laminations. Glulam is versatile ranging from simple straight beams to complex curved members.

Because of their composition large glulam members can be manufactured from a variety of smaller trees harvested from second and third growth forests and plantations. On the one hand the course of the bending stress along the beam depth is not linear. Use other member stress combinations e g. Glulam beams optimise the structural values of a renewable resource wood.

Factory made members can be formed into any practical shape and any desired size. Table specifications are provided with indicating conditions and assumptions used to calculate the member sizes. The full version allows you to design beams of any size. We can even fabricate complete circles.

The aitc timber construction manual describes this product and provides detailed guidance for curved beams and pitched and tapered curved beams. We can manufacture most custom curved shapes including s curves side curves parabolic arches double compound curves and tight radius curves with a radius as tight as 2 0. These tables are provided as a guideline. Connections are usually made with bolts or plain steel dowels and steel plates.

Glulam is available in both custom and stock sizes and one of four appearance classifications. Premium architectural industrial or framing. The beam span length is fixed for this demo version. Furthermore stresses occur during manufacture due to the bending of the lamellae.

Radial curved elliptical shapes and reverse curves are all possible.
