Civil engineers, architects, and mechanical engineers rely upon data derived from wind-tunnel tests for design of buildings, bridges, towers, and chimneys as extensively as do aeronautical engineers for design of aircraft. Development of special boundary-layer wind tunnels that successfully simulate natural wind in the atmospheric boundary layer has made this possible. Long test-section wind tunnels used for this purpose are of the closed-circuit and open-circuit types. Four common types of small-scale models are used for tests to yield data for design and analysis: rigid (static) pressure, rigid low-frequency balance, rigid high-frequency balance, and aeroelastic. Data from these tests must be used with wind data obtained from a meteorological station near the construction site to achieve economical designs having specified risk of damage or unacceptable performance.
