- OBM-RM - Enhance abutment transfer by creating it as a pier with footings and piles if they exist
Abutments modeled in OpenBridge Modeler with piles and footings can now be transfer to RM Bridge as pier elements, for analysis.
OBM model


RM Bridge model


- OBM to RM: Transfer issues - cross section mesh and negative length on link elements
It was fixed the issue on transfering cross section for cross frame elements. The boundary points were outside of the boundary line and the meshing was wrong, this is now corrected. Also, on transfering to analyzer at begin and end of the bridge link elements were giving negative length values, that were solved.
OBM model


RM Bridge model




- PSC Girders OBM to RM: MG with no materials
For Precast Prestressed Concrete Girder Bridges, it was assigned materials to girders and deck slab defined in OBM, when transfering the bridge model from OBM to RM Bridge.

In this way, the User will have several possibilities of connections, whether in a complete FEM model, or in a Hybrid model, such as deck modelled with FEM and Piers with beams and/or vice-versa.




- Eigen schedule action and Mass Participation Factors for Rotations
As asked by several of our Users, it was introduced in RMv11.16 the calculation of the mass participation factors for rotations in the eigen analysis. Now, Users can have access to mass participation factors in global translations, X, Y, Z and global rotations, RX, RY, Rz. Results can be seen in Main View and in the output *.lst file.




2.3 LEAP Bridge Concrete (LBC)
- Enhancements for PennDOT
. Show PennDOT DM-4 reference articles in design reports
. Custom maximum permitted spacing of shear connectors per PennDOT DM-4

. Support new deformed steel reinforcement per ACI
. Allow users to specify girder type as either adjacent or spread box girder for live load distribution factor calculation purpose
2.4 LEAP Bridge Steel (LBS)
- Enhancements for PennDOT
. Inclusion of self-weight of filed splice in analysis and design
. Renaming deadload of wearing surface and utility to add clarity in the load combinations
. Support the load rating of the PennDOT custom load group STR-IP
