There are buildings in my country that are more than 500 years old. That's longer than America has been a country

Yes but those buildings were not built with modern construction materials and design practices.

Reinforced concrete, in general, is not a material that can last hundreds of years without regular maintenance due to chemical reactions which degrade it over time.
