AThe use of wood in civil engineering dates back thousands of years. Wood is a
versatile, lightweight and durable building material. It is used in the construction
of houses, bridges, commercial buildings and even skyscrapers. Nowadays,
wood is also valued for its sustainable and ecological properties. Its use covers a
wide range of applications, from building structures to street furniture.

3. WOOD AS A SUSTAINABLE MATERIAL
The use of steel and concrete in buildings is almost a tradition, which is
understandable, as it has many advantages, making its use even more attractive,
but, in terms of sustainability, the production of these materials leaves something
to be desired, given that, given of research carried out to measure the impact of
civil construction on the environment inform that the sector, in developed countries,
is responsible for approximately 40% of the consumption of materials (75% of
which are natural, and the majority of them, non-renewable), 30% of energy
resourcesIt is32% of greenhouse gas emissionsstove.
Wood, as it is a natural resource, has the possibility of regeneration, making it
inexhaustible, as long as policies and control are in place to
avoiddevastation,Therefore, it is a material of great value in the search for
sustainable constructions.

5. ADVANTAGES OF USING
WOOD IN CIVIL ENGINEERING
a) Structural lightness:Wood is a
light material, which makes it
easier to handle and build
more elegant and efficient
structures.
b) Sustainability:As it is a
renewable resource, the use
of wood in construction
promotes environmental
sustainability.
c) Thermal and acoustic
insulation:The insulating
properties of wood provide
greater comfort and energy
efficiency to buildings.
d) Ease of processing:Wood is a
material that is easy to cut,
shape and assemble, allowing
for faster and more flexible
construction..
e) Aesthetics attractive:Ouseof

6. PROPERTIES OF WOOD AS A
CONSTRUCTION MATERIAL
Wood has unique properties that make it a versatile
and high-performance construction material. Its
strength, durability and lightness make it an attractive
choice for various civil engineering applications.
Furthermore, wood is a renewable resource,
contributing to the sustainability of projects.
Another important characteristic of wood is its thermal and
acoustic insulation capacity, providing comfort to building
users. Its texture and natural aesthetic also make it a
material appreciated by architects and designers.

8. STRUCTURAL APPLICATIONS OF
WOOD IN CIVIL ENGINEERING
Wood is widely used in various structural applications in civil
construction, from roof structures and bridges to scaffolding and
temporary shoring. Its strength and lightness properties make it a
versatile and efficient choice for structural solutions.
Glued laminated timber structures, trusses and frames are
common examples of the application of wood in civil engineering
projects, offering elegant and high-performance solutions.

10. Wood-Based Composite Materials in
Construction
In addition to solid wood, civil engineering also
uses wood-based composite materials such as
particle board, fiberboard and glued laminated
timber (GLA). These materials offer improved
properties such as greater strength and
dimensional stability.
The combination of wood with other materials,
such as resins and adhesives, results in
innovative and sustainable construction
solutions, widely used in fences, floors, roofs and
structures.
