Abstract


Floors are important to buildings as they provide stability and rigidity to the whole structure. Floors
also contribute significantly to the overall design load of the foundation. There are many various floor
system, precast
-
prefabricated or cast
-
in
-
situ,
dry or wet construction, each offers different advantages
and disadvantages. In this paper, commonly used floor systems and their examples around the world
with a focus on Malaysia will be presented providing a general literature of such floors. This will
be
followed by an introduction of an innovative lightweight floor solution known as timber
-
concrete
composite, a new floor system, now beginning to be used in some regions of Europe, Australia and
New Zealand. Timber
-
concrete composite floor is
a construct
ion technique where a timber beam or
deck is connected to an upper concrete flange using different types of connectors such that the
different materials, timber and concrete are utilized in their strongest properties, for instance timber in
tension zone an
d concrete in compression zone only. These two materials are then interconnected
with shear connectors ranging from flexible to fully rigid to provide the necessary composite action.
The aim of this paper is to introduce timber

concrete composite floor sy
stem to Malaysia and some of
the early experimental investigations already carried out at the Universiti Tun Hussein Onn Malaysia.
