The buildings are designed for loading criteria in such a way that they may be specified to meet the geographical requirements of any location. Combinations of dead load, snow load, live load, and wind conform with requirements of several model building codes.
Standards in ‘‘Metal Building Systems,’’ Metal Building Manufacturers Association, 1300 Sumner Ave., Cleveland, OH 44115 discuss methods of load application and maximum loading, for use where load requirements are not established by local building codes.

OPEN-WEB STEEL JOISTS
The first steel joist was produced in 1923 and consisted of solid round bars for top and bottom chords and a web formed from a single continuous bent bar, thus simulating a Warren truss. The Steel Joist Institute (SJI) was organized to promote sales of such joists in 1925 and has sponsored further research and development since then.
