Program Description: SDI FLOOR is a set of knowledge bases for the LRFD design of floor systems. Four knowledge bases are included in the set:

Bay Design
Beam Design
Girder Design
Table Generation

The Design knowledge bases provide cost optimized designs for user specified spans, material properties, deck profile, and cost data. Designs can be optimized for composite or non-composite or both types of construction. Alternate member selections are made for each design. For composite construction, shear stud spacing and other details are generated. A design report is made for each with full calculation details. If a design cannot be completed expert advice is given.

The Bay Design knowledge base provides cost optimized design alternatives for an entire bay. The only required input is the bay spans, material properties and uniform loadings. Optimization is based on input user costs. Beam spans in both directions and beam spacing are considered in determining the final design. A vibration analysis is also done for the final design. Ten alternate designs are provided.

The beam (deck ribs perpendicular to the beam centerline) and girder (deck rips parallel to the beam centerline) knowledge bases can be used to determine the least cost composite and/or non-composite designs for a range of beam depths. Final costs are calculated using input fabrication, steel and shear stud unit costs. Symmetric or non-symmetric rectangular, triangular or trapezoidal tributary areas can be specified for uniform loadings. Additional point or linearly varying line loads can also be included in the input. For girders, beams framing into each side of the girder can be specified and the corresponding point loads are then calculated.

System Requirements: IBM PC or fully compatible with 640 Kbytes of RAM, hard disk, 5.25 or 3.5 inch floppy disk drive. A CGA and a color monitor are strongly recommended. The program will run considerably faster if a math co-processor available.
