Update to Manual for Bridge Evaluation 3 rd edition

The current version of LBC we're using references the Manual for Bridge Evaluation, 2nd Edition as the basis for bridge rating. I'm wondering if there are plans to update this to reference the 3rd Edition instead. If such an update is planned, cou...

Interoperability of concrete diaphragm from OBM to LBC for open/close box beam types

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...

Camber on the beam, Beam need to be curved and follow the underside of the deck without gaps- Australia specific

The current beam hog modeling behavior is not as expected. While deck thickening can be applied, the supporting beams remain straight and do not conform to the underside profile of the deck. In reality, the beams should follow the curved shape of ...

( OBM > Deck > Thickness variation) Deck variations remain normal to alignment.

I am attempting to model a 3 span concrete slab bridge with thickened haunches over the supports. I am using a typical deck template. My thickness variations are shown in the first attachment. The Bridge has a 10 degree skew angle at the supports....

Simplifying Retaining Wall Construction: A Wingwall-Inspired Approach for Bridge Design

When the bridge needs a long “wingwall”, it break two part – a wingwall which is built with the abutment, and the rest part I call it “Retaining wall”. Is it possibly to make this retaining wall as easy as wingwall? That means like put the wingwal...

curved corners in bridge geometry

OBM should allow o define sharp corners for decks and barriers (in addition to rounded). Currently every turn is interpolated using spline type of line, without control from user end (regardless of the manipulation for the chord and distance betwe...

Bring back Active Chain Control or Similar Tool

In GeoPak, the Active Chain Control tool was very useful for selecting a particular chain or alignment and having the location information (station, offset, etc.) be display in a dialogue box. The location information would live track with the loc...
