As mentioned higher than, concrete is rather potent in compression, but weak in tension. Bigger earthquakes can produce very large shear masses on constructions. These shear masses matter the construction to the two tensile and compressional hundreds. Concrete structures with no reinforcement, like other unreinforced masonry constructions, can are unsuccessful through significant earthquake shaking.
Boston City Hall (1968) is usually a Brutalist style constructed largely of precast and poured in position concrete. Concrete buildings are more proof against fireplace than those manufactured employing metal frames, since concrete has decreased heat conductivity than metal and will Consequently last lengthier under the similar fire conditions.

After in position, concrete provides a great energy performance in excess of the lifetime of a building.[114] Concrete walls leak air considerably under Those people made of Wooden frames.[115] Air leakage accounts for a substantial share of Power decline from a house. The thermal mass Homes of concrete improve the effectiveness of both of those household and business buildings. By storing and releasing the Strength needed for heating or cooling, concrete's thermal mass provides 12 months-round Gains by lowering temperature swings within and reducing heating and cooling expenses.
