Wood is the greatest gift of nature to mankind. It has created the revolution in the lifestyle and living. Wood is durable and its strength and durability varies at different levels. There are several factors which directly or indirectly affect wood strength. These factors are differentiated as:
- Biological Factors
- Environmental Factors
- Natural Defects & Irregularities
- Dry Rot
- Wood Worm
These factors play crucial and decisive role in the assessment of wood. Besides, the strength of wood is also determined using three-point bend test. In this type of strength test, the height and width of given wood sample will be measured by placing it in a specially constructed three-point bend testing apparatus.
Increase in the temperature strength affects the strength of wood. On very high temperatures, the strength of wood is decreased substantially, and it crosses the threshold value. Heat reduces the strength, and the effect is very high in steam or moist air than in dry air.
Another significant factor to consider while discussing strength of wood is duration of loading. With the flux of time, there are good chances of appearance of creeps and this will reduce the wood strengths of time duration.
Furthermore, important factors like the wood grain, color, stability, strength, finish, etc. are also quite relevant points that one should keep in his/her mind while buying the wood. Buying best quality wood for your home or office is not a difficult task, once you become fully aware of the factors associated with quality of wood. Finally, make sure that you check the wood species. This would help you in finding the best quality wood that will match your requirements.
Wood is solid building foundation that makes an integral part of construction. With high quality wood, you have reasons to add strength to your home and/or office.
