Advantages And Disadvantages Of Wood For Construction
September 8, 2021
Wood is a forest product from natural resources, is a raw material that is easily processed to be made into goods following technological advances. Wood has several properties at once, which other materials cannot imitate. We can also see the application of wood pilings in several places, such as parks, recreation areas to ports. discover more now
In addition, wood also has several advantages and disadvantages when used as construction, here are the advantages and disadvantages of wood:
• High strength with low specific gravity,
• Resistant to chemical and electrical influences,
• Easy to get and relatively cheap. It is easy to obtain and the price is relatively cheap compared to concrete or steel.
• Dry wood has low thermal and electrical conductivity, so it is very good for partitions,
• Has a distinctive side of beauty and high art,
• Easy To Work,
• Resistant to earthquakes, because wooden structures are not as rigid as concrete structures and are relatively light where the magnitude of the earthquake force acting on a building is influenced by the building’s weight,
• Easy to replace in a short period or does not require a long time when compared to other building materials such as concrete or steel if there are repairs.
• Able to withstand tensile, compressive (push), and bending forces.
• Vulnerable to fire hazards, due to the flammable nature of wood. In contrast to concrete or steel, there is still tolerance for heat temperatures, while wood has no tolerance.
• Relatively large expansion and contraction. Large expansion and shrinkage will occur in wood that is still wet or freshly felled so that the wood that has just been felled must be dried to death before being used to avoid greater expansion and shrinkage.
• The long-term loading of the deflection is very large. Wooden beams that have been loaded for a long time will cause large deflections as the age of the wood increases or the strength of the wood decreases.
• Cannot be used for long spans. With the use of wood in long-span structures such as long horses, the resulting wood deflection is very large.
• Less homogeneous due to natural defects such as the direction of the fibers that form cross-sections, spirals, diagonals, knots, and so on. Lack of homogeneity in wood due to natural defects such as this can reduce the quality of the wood and its strength so that it is not appropriate when used as the main structure.
• Need special care. Such as painting to slow down the weathering of wood and what needs to be considered is to protect the wood from insect attacks, be it beetles, termites, and other insects that can result in a decrease in the strength of the wood.
