Fiber Mesh Cross Sectional Analysis

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 ...

Staged Construction Optionality

Staged construction is a very common construction methodology. The current process of modeling staged construction in OBM is to model each stage as separate bridges. This creates problems when modeling a steel I-girder bridge as the cross-frames b...

PMM non-linear springs

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...

Include ability to model curtain wall under end bent

Please include ability to model curtain wall under end bent, similar to backwall. This curtain wall is a great tool when working on projects when new fill required to place is not significant enough to just an independent retaining wall but is sig...

Ability to automatically generate 3d linear features/Linestrings from OBM elements

Generation of 2d decorations and solids are insufficient for full coordination with road geometry teams and they regularly need to provide 3d linestring geometry as part of the roadway design for bridge barriers, wingwall edges for earthworks, etc...

Anisotropic shell elements in RM Bridge

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...

Approach Slab Line Offset

Currently the approach slab line uses an offset distance to place it. that offset value just shifts the line that distance along the alignment, which is not what we want especially on curved bridges. That offset distance needs to be a copy paralle...

RM Bridge Envelopes for Shell Forces

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.

Allow LFD substructure analysis with an LRFD Superstructure in LEAP Steel

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...

RM Bridge update to use the correct AASHTO reduction factor for reinforced/prestressed concrete based on tensile strain in reinforcing at ultimate limit state.

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...
