A microcomputer‐aided system has been developed for interactive design and drafting of connections in steel buildings made of standard. rolled‐I sections, called STEELCON. The basis of design is AISC specification. In addition to interactive design, STEELCON can displaylplot any isometric view of the connection plus three orthographic views, i.e., front, side, and top face views. The orthographic views show all the necessary details for fabrication and construction of the connections. Interactive design and drafting of two different moment resisting connections are presented. They are the shop welded and field bolted framed flange plate connection and the shop and field welded flange plate connection.
