There’s a need for improved interoperability between OBM and LBC when working with concrete diaphragms in open or closed box beam configurations. Specifically, the transfer of diaphragm data—such as start, end, and interior diaphragms—for box gird...

Allow automatic POI definition from bearing to bearing (for camber and deflections)

For final bridge plans involving a steel bridge, we need to report dead load deflections at either the 10th or 20th points along the span—from bearing to bearing. While the program does calculate these points, it currently measures them from the e...

RMBridge--Seismic Eigen Analysis with CQC Method for Repeated Sub-Systems

In eigenvalue analysis of repetitive structures—where identical sub-systems exist independently within a single model—the same frequencies and eigenmodes are often assigned repeatedly to each sub-system. This leads to an issue with the CQC (Comple...

Finished Grade Elevations on Approach Slabs

I don't believe we can select the limits of the approach slabs when running the deck elevations report. Many DOTs require slab elevations to be reported on the approach slabs in addition to the bridge decks - adding this functionality would be gre...

Rm Bridge: Use local axis for leading envelope displacements when local axis results are being reported

When reporting envelope .sup files, the leading value when reporting displacements is always global, while the results displayed are either local or gobal (selected by the user). This is inconvenient for displacement envelope result reporting when...

Allow for different shaft fixity in one model

A column on drilled shafts can have different fixity locations for different load cases. Suggest allowing analysis of the same bridge with different fixities rather then needing to create multiple models with varying fixities for simplicity.
