ABOUT mBrace3D

In many ways, mBrace3D is similar to today’s other commercially available structural software for curved steel bridges. The difference, however, lies primarily in its significantly lower cost, the aim being that more bridge erectors and designers embrace the benefits of 3D finite element analysis in their daily practice.

Designed by structural engineers directly, mBrace3D is capable of running several types of analyses on complex plate girder and tub girder systems: linear elastic, eigenvalue buckling, eigenvalue frequency, and geometrically nonlinear analyses. Parametric definition allows for easy and quick generation of 3D shell models, which allows for unrivalled accuracy (for example, over 1D line girder and 2D grid models), as recommended by the most recent AISC/NSBA guidelines on steel bridge design and construction analysis.

While initially the focus was on the erection and deck placement analyses, and in particular, the detection of potential structural instabilities, mBrace3D is now also able to compute influence surfaces for the composite steel/concrete system, allowing for vehicle load optimization (VLO) analyses.

Previously known as UT Bridge (the software was in its very early phases the product of a TXDOT funded research project at the University of Texas at Austin), mBrace3D has become a commercially available software but remains free for students as well as researchers, and remains relatively inexpensive for bridge erectors and designers, compared to its competitors.
