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.

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...

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...

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...

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, ...

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...

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 ...

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...

Introduction of Transverse PT for shell element segmental box girder.

I would like to start using RM Bridge with shell elements for transverse analysis, however, I have just found out that currently it does not provide envelope results for shell forces, this is an essential tool for live load transverse analysis.
