Concrete domed roofs protect schools against natural disasters

A concrete domed roof design known as "Concrete Thinshell" has been built on some schools in Utah and in Oklahoma to help them withstand storms, tornadoes and other disasters. The structure is assembled by inflating a roof membrane to form a dome with steel reinforcing bars across the underside, and then the "reinforcing steel is built up to 4 feet high around the base of the dome and sprayed with shot-crete," according to the website of Leland Gray, a Utah architect who created the concrete roof. In Locust Grove, Okla., the concrete domed roof atop an elementary school there regulates indoor temperatures and saves on energy use.
