Choosing the right materials for the building structure, different factors should be considered, including:
Strength and resistance: Materials that are stronger and more resistant work better and more stable in the building structure. For example, steel and concrete are used in tall buildings with high loads due to their high strength.
Processability: Materials that are easy to process and shape, perform better in designing and building diverse and complex structures. For example, steel is used in tall and complex buildings due to its flexibility and simple processing.
Flexibility: Materials that have high flexibility are more resistant to earthquakes and loads that can lead to deformation of the building. For example, steel is used in seismic buildings due to its high flexibility and earthquake resistance.
Thermal and sound insulation: Materials that have high thermal and sound insulation capabilities are used in buildings that must be protected against sound and temperature. For example, double-glazed glass and white polyethylene are used as heat and sound insulation in buildings.
Cost: The cost of materials in building structure design plays an important role in their selection. For example, the use of expensive materials such as steel may be rare in buildings with limited budgets.
Building use: The type of building use should also be considered in the selection of materials. For example, in residential buildings, materials with high thermal and acoustic insulation capabilities, as well as simple processing and shaping capabilities, are used more often.
Harmful effects on the environment: The harmful effects of the use of any material on the environment should be considered in their selection. For example, the selection of materials with the least harmful effect for the production of greenhouse gases during the life of the building should be considered.
In general, in the selection of materials for the building structure, attention should be paid to various factors, including resistance, processability, flexibility, thermal and sound insulation, cost, use of the building, and harmful effects on the environment. In each construction plan, the type and amount of use of each of these materials may be different
