Add a separate limiting tension stress for the top of girders near interior supports. AASHTO LRFD permits the use of a limiting tension stress at the top of girders near interior supports for Service III different than the limiting tension stress ...

When performing a superstructure replacement, it is common to design the proposed superstructure in LRFD but then analyze the existing substructure capacity in LFD. Currently with LEAP Steel, because the superstructure was designed in LRFD the sub...

The Live Load (LL) library in LBS currently allows importing .cs3 files, which are legacy formats from the stand-alone versions of CONSPAN and CONBOX (see screenshot below). However, in the latest releases of LBC under OpenBridge Designer (OBD), i...

In LBS (LEAP Bridge Steel), it appears that cross frames (CF) and stiffeners are not exported to the DGN file. The screenshot below is from LBS Tutorial 2, which highlights this limitation. The goal is to streamline CAD detailing by having LBS gen...

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...

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...

The current RM bridge ultimate capacity calculations allow for material reduction factors only, which are not used by AASHTO for reinforced and prestressed concrete. AASHTO concrete reduction factors for flexure and P-M capacities are based on the...

We would like to ask a PMM non-linear spring for modeling Plastic Hinges for reinforced-concrete Columns. This PMM springs are used for modeling the Moment-Rotation (M-R) behavior for different axial loads (P). The PMM spring should be able to cap...

This is a feature request for RM Bridge 1. When the main graphic windows show the model, the right-click menu is enabled for the the side graphic window Please refer to attached 1.png. 2. But when the main graphic windows does NOT show the model, ...
