About this calculator
Our juntas dilatação calculator is a practical tool for calculating material expansion in constructions. Expansion is the change in size of a material due to temperature variation. Our calculator considers the linear expansion of 3 mm/m, one of the most common in construction materials.
To use this calculator, you will need to know the initial and final temperatures of the material, as well as its width and length. The standard temperature is 20°C, but you can adjust it as needed. Additionally, it's essential to remember that expansion is more pronounced in materials like wood and metals.
This calculator is useful in various situations, such as building, bridge, or any other structure that needs to consider material expansion or contraction over time. It's crucial to have expansion in mind to avoid damage or structural problems.
Frequently asked questions
What is the reason for the 3 mm/m expansion?
The 3 mm/m expansion is a common average for many construction materials, such as wood and metals. However, it's essential to remember that some materials may have different expansion rates.
What is needed to use this calculator?
You will need to know the initial and final temperatures of the material, as well as its width and length. Additionally, it's essential to consider the standard temperature of 20°C.
When to use this calculator?
This calculator is useful in situations like building, bridge, or any other structure that needs to consider material expansion or contraction over time.
How to avoid structural problems due to expansion?
To avoid structural problems, it's essential to consider expansion at the design and construction of structures. This can include installing suitable expansion joints and choosing materials with similar expansion rates.
