NSBA Updates LRFD Simon Software

The National Steel Bridge Alliance (NSBA) recently released several updates to the Load and Resistance Factor Design (LRFD) Simon software, which aids bridge engineers in preliminary steel plate and box girder design. The new additions include:

  • 8th Edition AASHTO Specification support. All specification checks are now consistent with the current AASHTO Specification.
  • Input file verification. When opening files and before running the analysis engineer, LRFD Simon now performs an input verification.
  • “Best Design” input file creation. After a successful design run, LRFD Simon now generates an input file containing the web and flange dimensions of the successful design.
  • Updated user documentation

LRFD Simon is a powerful line-girder analysis and preliminary design program for steel I-shaped plate girders and multiple single-cell box girders. It allows users to quickly produce complete steel superstructure designs in accordance with the 8th Edition AASHTO LRFD Bridge Specifications. And it’s free!
