REMINDER: Register for the NSBA Networking Event at SCOBS 

The National Steel Bridge Alliance (NSBA) invites you to a night of networking with your colleagues in conjunction with the 2017 Annual Meeting for AASHTO Subcommittee on Bridges and Structures. This year's event will be located at the Mobius Science Center in Spokane, WA -- just a short walk from the Davenport Grand Hotel --and will include a special interactive exhibit where you will get to try your hand at installing a bolted splice

Please share this invitation with your colleagues who may be attending AASHTO SCOBS. We look forward to seeing you in Spokane!

LRFD Simon Update Expected Late 2017

LRFD Simon has a long history of serving as a key tool to assist engineers with the preliminary design and analysis of  steel plate and tub girder bridges.  With thousands of downloads since its relaunch, Simon has allowed engineers to realize efficiencies in the early design stages that make steel an even more appealing material choice from the start.

Many updates are being incorporated this year to improve the user experience and maintain compliance with governing codes. A number of the more profound updates are summarized below.

  • AASHTO LRFD 8th Edition Revisions.  It is vital that design software stay current with the ever changing  design specification.  The next update to Simon will incorporate the applicable changes in the upcoming AASHTO LRFD 8th Edition manual.
  • Load time input file validation.  Issues can arise when an improper value is input into Simon. This next version of Simon will alert you to any errors you might have during load-time so that they can be more quickly found and corrected.
  • Automatic “best design” input file creation.  When running the Simon in "design" mode, the program performs a number of design trials, finally settling on a "best" design. The next version of Simon will provide the ability to create a new analysis input file from the final designed member sizes on the cross section.  This will allow the user a better baseline from which to tweak the design by making additional "analysis" runs using the new analysis input file.

Look for this new version of LRFD Simon later this year.  And if you have not downloaded and installed the current version, you can do so by visiting the LRFD Simon Registration and Download page.
