LFD design code is used in superstructure rehabilitation projects for bridges that are originally designed with LFD. Please consider making it an option in LEAP Steel similar to LEAP concrete.

Currently when defining the horizontal earth loading on an abutment, the only option is to have a triangular loading from top to bottom. The "Mag2" input box (for the load magnitude at the top of the load) is set at 0, greyed out, and cannot be ed...

There appears to be a discrepancy in wind load calculations—specifically, the gust factor of 0.85 remains different from AASHTO standards. However, the FDOT Structures Design Guidelines (SDG) 2025 now allow the use of AASHTO Article 3.8, which may...

The world famious bridge softwares such as Lusas, Midas Civil, Sofistik, Larsa 4D. All of them have been developed Grasshopper Plugin to increase the bridge modeling capacity. Lusas Grasshopper plugin: https://www.lusas.com/products/external_plugi...

When a load is defined in LBS, it is defined corresponding to a certain construction stage. However, there is no way to change the stage after the load is defined. The user has to delete the load and redefine it in a different stage. (e.g. allow a...

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...

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...

The implementation of FEM shell elements as a supplement to the beams in RM Bridge Enterprise, is a useful tool. Sometimes it will be useful to model the shell elements with different properties in the longitudinal direction compared to the transv...

Con sider adding fiber-mesh tools for cross section analysis to RMBRIDGE. This allow the use of different materials in the cross section. This is important in seismic analysis for the definition of the Moment-Curvature properties. This feature is ...

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 ...
