Glulam


Glulam - eco-friendly, strong and with wide possibilities 

Glulam is a completely eco-friendly material, and laminated timber beams can be used for everything from large industrial buildings to single family homes. Glulam offers wide freedom of architectural design. http://www.moelven.com

Glulam Student Center Opens at Quinnipiac University in Hamden, CT

Last week we visited Quinnipiac University to tour the finished York Hill Campus Student Center. Below are several of the photos we took of the interior. As you can see, the warmth and beauty of our product creates a visually stunning structure throughout the entire interior. This was one of the most complex projects we have ever supplied material for and we enjoyed seeing the finished product.

Laminated timber

Engineered wood construction: glued laminated timber

In Europe, structural glue laminated timber is widely used in constructions where span width is an issue and/or the unique beauty of the wood is to be exploited architecturally. Glulam beams and columns have a strong aesthetic appeal, as the structure of a building can be expressed in the exposed beauty of the wood.
Glue laminated timber – engineered wood beams and columns - are used in homes, schools, sports halls, railway stations, industrial and commercial buildings, such as shopping centres and expo buildings, and public buildings, such as museums and concert halls. They are also used in landscaping and infrastructure applications such as glulam bridges. Glulam beams and columns come as standard products, with a variety of cross-sections and lengths. Custom designed beams and columns are prefabricated according to customer needs and can include curved shapes and mechanical interfaces to concrete or steel structures etc.
Glulam is a mature technology in Europe, where large span buildings are still in use after almost 100 years.

Glulam Truss


Glued Laminated Timber (glulam) = (my def.) wood structural member made up of laminating (gluing) relatively small pieces of wood together (in layers) to make one much larger (and stronger) than the constituent pieces.

The (glulam) members can be used for:

    substitution for big solid timbers that are unavailable (or too costly)
    for timber sizes unachievable with solid sawn timbers
    for timbers requiring greater strength and/or stiffness than solid timbers


For use in simple framing ... glulam can be used for ...

    joists, beams, girders, rafters
    posts or columns


The thing about glulam is that while providing support - it can also be very attractive, and thus we could categorize the use of glulam also in terms of ...

    un-exposed
    exposed

Glulam can also be made into curved shapes, and thus ...

    cambered beams
    curved beams (circular shape, S-shaped, whatever)


... and tapered, thus

    tapered beams (single or double taper)
    pitched and tapered curved beams
    arches with tapers

Glulam


Glulam, short for glued laminated timber, is an engineered wood product. Large glulam members are produced from smaller pieces of stress graded and seasoned timber, known as laminates.

Glulam originated in Germany around 1900 but didn't make its way to Australia until the 1950s. It is now used for both structural and decorative applications.

Manufacturing
The manufacturing process produces large and long length glulam members, which also results in increased strength when compared to that of the individual member. This also means that much larger pieces of timber can be produced than would otherwise be possible with traditional solid sawn timber. Glulam is consistently stronger than solid timber, in part due to the reduction in size and occurrence of natural defects.

Timber laminates used in the production of glulam are typically finger-jointed into continuous lengths and available in a range of both softwood and hardwood species. The thickness of the laminates will depend on the application and species used. Prior to gluing, the laminations are accurately dressed to exact and uniform thickness. The laminates will also be clamped together under constant pressure until the glue has cured. Once glued, members are planed, cut to exact size and may be coated with a water repellent sealant.

Many manufacturers are able to produce a variety of shapes and sizes at the designer's request. The length and shape of glulam sections is limited only by manufacturing, transport and handling capabilities.

Australian manufacturers generally produce deep sections with the laminates horizontal. In Europe, glulam has been used with face and edge lamination to produce deep sections with vertical laminations; this technique may also be used by some Australian producers.

It is possible to manufacture a glulam beam with higher strength laminates in areas of high stress - such as in the top or bottom laminates of beams - and lower strength laminates in the areas of low stress. Steel and fibre reinforcement can also be incorporated in areas of high tensile stress and may be positioned either parallel or perpendicular to the laminate direction.

Suitability for structural applications

Glulam offers many benefits when it comes to structural applications:

    Large section sizes and long lengths - glulam can be manufactured curved or straight and is often used as structural beams. Finger jointing allows for long lengths.

    Increased strength due to the laminating process - glulam is stronger than solid timber as it has fewer natural defects and a wider distribution. It is also comparable to steel in strength but is much lighter.

    A high degree of dimensional stability - glulam is manufactured from seasoned timber and is therefore less prone to movement caused by changes in moisture content. However, care needs to be taken if they are used externally or in an environment with rapidly changing humidity (such as an indoor swimming pool). Swelling and shrinkage may lead to splitting or , in an extreme event, delamination of the beam.

    Reliability - glulam is manufactured to strict quality requirements from stress- graded timber of known structural capacity. There are glulam quality assurance programs operating in Australia, but not all manufacturers may belong to them.

    Chemical resistance - glulam is resistant to most acids, rust and other corrosive agents. Typical uses in corrosive situations include animal hide curing complexes, fellmongerys, fertiliser storage and swimming pools.
