Structure fires and wildfires result in significant loss of life and property in the United States each year. In addition to the direct losses of fighting fires, relocating residents and rebuilding, large fire events can cause substantial indirect losses to communities. There has been an increase in single family and multifamily structure fire losses, partly due to increased use of combustible construction methods. This presentation will investigate the causes of these fires and provide balanced design recommendations using both active and passive fire protection strategies. It will suggest several noncombustible concrete building systems to help reduce risk of fire loss in buildings.
