UPDATED: NSBA Splice
NSBA Splice takes the time-consuming task of designing and checking a bolted splice connection and rewrites the process with a simple input page and output form. NSBA Splice can be incorporated as a design tool on plate girder bridges allowing the designer to quickly analyze various bolted splice connections to determine the most efficient bolt quantity and configuration. Based upon the updated AASHTO LRFD 8th Edition, Splice allows the user to explore the effects of bolt spacing, bolt size, strength, and connection dimensions on the overall splice design.
Splice is presented in an easy to understand Microsoft Excel spreadsheet format allowing users with Microsoft Excel 2010 or later to access and utilize. Included in the download is the design spreadsheet as well as two completed examples. The examples are the inputs and solutions for Examples 1 and 2 presented in Bolted Field Splices for Steel Bridge Flexural Members.
The current version of NSBA Splice (v3.08) was released on May 1, 2020 (Release Notes).
