INTRODUCTION
Laminated timber frame (LTF) is a new, modern and innovative structural system that
uses multi- layered panels that are made of solid wood whose layers are glued together at 90
degrees (Tuhkanen and Rauk, 2019). These frames are stable and have less shrinkage possibility
because of which it can be used for various applications such as walls, floors and roofs.
Nowadays usage of these modern Cross laminated timber frames has increased, in fact many
construction industry organizations are using it as an alternative to concrete structures or
structural steel. The main objective of this report is to analyse advantage of using modern long
span laminated timber frames over pre-cast concrete or structural steel. This topic is important to
be studied because it will help in identifying ways in which usage of laminated timber frames is
much more benefitable for construction as compared to usage of precast concrete or structural
steel. Laminated timber frame are environment friendly. It can also be said that usage of these
frames is a positive initiate towards achievement of environment sustainability. It has same level
of durability and strength as compared to pre-cast concrete or structural steel. It is cost effective
and can be used for construction of different types of commercial and residential buildings. It can
provide flexibility in terms of shape and size to the building. It can be used as per the
requirements of owner. Additionally, provision of fire protective finish helps in enhancing its
overall fire performance because of which its durability and strength is also increased.
MAIN BODY
In recent years’ usage of laminated timber frames has increased for construction of
modern buildings. It is prefabricated panel wood engineered product which is manufactured by
gluing different layers of solid lumber at perpendicular angle. In construction it is used for
different purposes such as for flooring roof assemblies, walls and for various other purposes.
Some of the main advantages of long span laminated timber frames over concrete structures or
structural steel are as follows:
 Strengths and durability: laminated timber frames have high strength and durability. Gluing
more than two frames together increases its strength and durability because of which its
strength increases. It is quite similar to precast concrete as compared to traditional timber
frame designs (Chang, Wi and Kim, 2019). Durability of these frames is not less than steel or
precast concrete frames. Due to its strength and durability its usage in construction industry
