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...

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...

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...

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...

Model a straight bridge on a curved alignment

The ability to create a straight bridge when the alignment transitions from tangent to a horizontal curve on the bridge. Currently the deck ends are controlled by the bridge skew from a radial line at the end of the deck rather than from the tange...

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...

Allow Pier Diaphragms to fall between the beam ends rather than encasing the beams inside the diaphragm (TDOT).

TDOT doesn't encase the beams inside of the pier diaphragms. TDOT places an 18" diaphragm between the beam ends with bent-up strands being used for anchorage into the diaphragm. If the bridge is skewed, the diaphragms are skewed at a different ang...
