2.3 Definition of Glulam
Glued laminated timber, commonly referred to as Glulam
is a structural timber product manufactured by gluing together individual
pieces of dimensioned and strength graded timber under stringent manufacturing
condition. It is an ideal for load bearing structure where long spans are
desired. It offers the architect artistic freedom without sacrificing
2.4 Strength of Glulam.
As we know glulam timber is a structure that use many
type of timber and gluing together individual pieces of dimensioned and
strength graded timber under stringent manufacturing condition. However, glulam
have its own strength among them. Five factors contribute to strength of glulam
that can be considered are as follows:
2.4.2 Strong and
2.4.4 Easy to
machine and assemble
2.4.1 Design flexibility
Glulam can be manufactured to wide range of dimensions.
Laminating process allows timber to be used for longer spans, heavier loads and
complex shapes. Glulam structural beams can be custom built to almost any shape
and size – be it straight, cambered or curved, allowing the designer greater
freedom in design and form. This ability gives huge potential for the
manufacture of arches and portal frame. Glulam is easy to combine with other
material. In interaction with other material, glulam creates visual appeal
within the building.
2.4.2 Strong and resistant
Glulam has superior strength properties and high
strength to weight ratio, besides it does not burn easily. Fire in Glulam goes
out by itself unless the beam is directly exposed to flames. The carbonized
layer protects the beam against further destruction from fire. Glulam
constructions can be made to be extremely fire safe. It easily fulfils the fire
resistant standards, set by the authorities.
2.4.3 Visually attractive
Provides unlimited opportunities to create aesthetically
demanding and attractive structures.
2.4.4 Easy to machine and assemble
Glulam members can be easily handle and on – site
machining can be done with normal hand tools. Glulam can be prefabricated
including with connections ready for speedy installation. Glulam also can be easy
to transport and assemble.
2.4.5 Ecologically sustainable
Timber is the only 100% renewable raw material. It
stores carbon rather than emitting it. Manufacturing wood products is less
energy – consuming than other building materials. Timber provides natural
warmth and beauty.
