General Information

MDX Software Curved & Straight Steel Bridge Design & Rating is currently in use by many ENR Top 500 design firms and state DOTs to design and rate steel girder bridges for compliance with AASHTO Specifications: the 17th Edition of the AASHTO Standard Specification for Allowable Stress Design (ASD) and Load Factor Design (LFD), and the 4th Edition LRFD Bridge Design Specifications.

This package is actively maintained and has been continually enhanced as a result of the high level of technical support that we have been providing our users over the past 10 years.

The overall "user friendliness" of this steel bridge design software package has been dramatically improved with the recent release of Version 6 and its all new user interface. Another development of interest is the recent implementation of the LRFD provisions for curvature.
