Use of timber and engineered materials
for multi-storey buildings
Abstract:
Timber
is a natural material characterized by many advantages such as high
strength-to-weight ratio, particularly important for buildings in
earthquake-prone areas, sustainability, and aesthetic appearance. However, the
inherent low ductility, anisotropic behaviour, and uncertainty of mechanical properties
sometimes prevent a more extensive use in structural engineering. In order to
improve the reliability, engineered materials such as Laminated Veneer Lumber
(LVL) and plywood have been developed and are commonly used in many countries
of the world such as
The
seminar will present an overview on the use of timber and engineered materials
for multi-storey timber buildings. Different
solutions for the vertical structures, such as shear walls and moment resisting
frames, and the floors, such as traditional floors, stress skin panels, and
concrete-timber composite systems will be presented. The lateral resistance of
the three dimensional structure against the earthquake and the need for achieving
a diaphragm action on every floor will be discussed. The possibility of
combining timber structures with bracing systems made of steel and/or concrete
will also be highlighted. Finally, the results of some long-term and failure
tests performed on concrete-timber composite structures will be presented,
along with some quasi-static tests currently ongoing at the University of
Canterbury on beam-to-columns subassemblies prestressed
with unbonded tendons.
