Answer:
based on what I have learnt about structural materials I think steel-reinforsed concrete is the best compared to other forms of materials for buildings
Explanation:
The reasons being that
1. Steel is a ductile material as compared to the brittle nature of concrete, thus stopping any sudden failure. And steel can take in tension force which concrete is particularly weak in.
2. Steel as a material has very good bonding strength with concrete, which helps them start a nice casual conversation, connect and then hold each other in place and not exist as separate entities forced to stay at one place.
3. The Modulus of Rigidity remains same for tension and compression, in case of steel.
4. The steel is always recyclable. so no wastages
5. Thermal Expansion Coefficient of both steel and concrete is same, coming to an approximate 12*(10)^(-6)/°C. This facilitates saving their relationship through the summers and winters, never having to go through the pain of breakups.
with all these properties the building could last for 1000 years
