Describe the factors for selection of construction materials on the basis of strength. 

1 Answer

Material must be selected for their ability to support the loads imposed by the building over the whole life of the building. An appropriate structural system and correct selection of structural materials can reduce excess material use and waste and increase the building adaptability for other uses. Material should be used as per their functional requirement. A highly durable material may provide the most sustainable solution, if it reduces maintenance or replacement requirement, but the material should also be appropriate for expected life of the building.
