June 25 Bridge Webinar to Cover Continuous Span Standards and LRFD Software

The National Steel Bridge Alliance (NSBA) is offering a one-hour webinar on new continuous span standards and updates to SIMON LRFD software next Thursday, June 25, beginning at noon EDT.     

The new standards address bridges with five girders in the cross section under balanced geometry configurations including center spans between 150 ft and 300 ft and end spans at 78% of the center span. Girder spacings for these geometries range between 7 ft, 6 in. and 12 ft. Plate sizes have been optimized for cost and provide the necessary information to quickly compare alternatives and establish preliminary pricing. All solutions are based upon the AASHTO LRFD 7th edition and HL 93 live loading. Homogenous and hybrid plate girder solutions are prepared with the homogenous solutions utilizing ASTM A709 50W steel throughout the girder, while the hybrid solutions use ASTM A709 50W steel for the web and ASTM A709 HPS70W steel in selected portions of the flanges.

The standards, developed in conjunction with Commonwealth Engineers and Consultants, Inc., of Providence, R.I., use NSBA’s SIMON software. In addition to tabulated data for each of the 88 standard solutions, attendees will receive the SIMON LRFD input files for use by registered users. These files will allow engineers to quickly make adjustments based on their specific geometries or loading. The webinar will provide an overview of the software and its major updates including compliance with AASHTO 7th Edition; girder web depth optimization; internally calculated distribution facts; and consideration of deck pour sequences.

The cost of the webinar is $125 for AISC/NSBA members, $190 for non-members and $100 for students and educators. (Fees are based on a per-site connection basis. Purchase one site connection and any number of members in your company or organization may view the webinar at that site connection. All attendees are eligible to receive a continuing education certificate.)

Registrants will receive access to a PDF file of the presentation slides prior to the webinar, CEU/PDH certificates for all attendees upon completion of the live webinar (0.10 CEUs/1.0 PDHs) and complete instructions for accessing the live webinar.
