SIMON: A PLATE-GIRDER DESIGN PROGRAM (LOAD FACTOR DESIGN)

The computer program SIMON, which was developed by U. S. Steel Research to prepare a preliminary design of a plate-girder highway bridge, was initially limited to the Working Stress Design method in the specifications of the American Association of State Highway and Transportation Officials (AASHTO). Recently, SIMON was expanded to include the Load Factor Design method, an alternative method new included in the AASHTO specifications. Load Factor Design is a method of proportioning structural members for multiples of the dead and design live loads such that a more uniform live-load capacity is achieved than with the Working Stress Design method. With the expanded program, a user of SIMON has the option to select either the Load Factor or the Working Stress Design method. The present report describes the additions made to SIMON to include Load Factor Design.
