changes and reset all the strand patterns unexpected under BIM workflow.  Minor changes to bridge geometry caused the unexpected erasing of 

analysis/design results.  False warning message about the change that will affect analysis and design results 

even though there is no change.  Issue related to the calculations of effective prestressed P/S strand used in shear 

design check for prestressed concrete girders.  Issue related to the impact of development length on the shear design check for

4.Retry installation

1. RM Standalone Workflow in OpenBridge Designer (OBD)

New settings for RM Standalone workflow in OpenBridge Designer (OBD) are now available under “Settings” in OBD.

Note: Setting 1 is the default setting. Users need to switch to Setting 2 to access the RM project folder and run a batch mode.

2. Enhancements in GUI 2.1 Export Modeler variable to excel

A new option for exporting variables to excel in Modeler is now available. Users will be able to export all or a selected range of variables from a segment to excel.

2.2 Export load cases in excel (*.xls) and list (*.lst) A new option for exporting load cases in excel (*.xls) and list (*.lst) format is now available.

2.3 Create a list file for cable lengths under loading in schedule actions

A new option for generating a list file for cable lengths under loading in schedule actions is now available.

2.4 Wobble factor update

The following menu allows to define wobble factor by entring “K” value. The K value is defined differently in Eurocode and in other codes.

Eurocode (EC) and other codes following the EC rules (OE-Norm Eurocode, German Standard - DIN, Portugal Standard, Norway Standard – NS, Eurocode Norway, British Standard – BS 5400, Australian Standard – AS 5100, Newzealand Standard – NZS 3101, Sweden Standard, Spanish Standard EHE, Finish Standard, French Standard, Austrian Standard – B4200, and Austrian Standard – B4700), β is equal to K but °/m instead of rad/m.

β is equal to K but unit is °/m instead of rad/m

For other codes , β is equal to K / Friction, K being expressed in Rad/(m or Foot) and β being expressed in °/ (m or foot)

β is equal to K / Friction, K being expressed in Rad/(m or Foot) and β being defined in °/ (m or foot)

3. Enhancement Shear-stress Leading Envelopes Min/Max TauXY and Min/Max TauXZ It’s now possible to obtain the shear stress envelopes for load case combinations separately in Y and Z directions. By RMSets definition, the User can obtain plot diagrams, *.lst and *.xls output files for envelopes of shear stress results in XY and XZ directions. The user needs to assign the shear stress leading points in the cross-section’s definition to obtain the shear stress envelope results after running the model.

RM Sets definition for Y direction:

RM Sets definition for Z direction:

In schedule actions, users need to use the “DgmSet” command to plot diagrams and use the “DoRep” command to generate *.lst and *.xls output files.

4. Enhancement in Wind Refined Method: increase the accuracy of results

The “Wind Refined” option has been enhanced to improve the output result's accuracy without affecting the analysis time. It has been achieved by increasing the number of omega integration points from 41 to 161 without augmenting the running time. This measure accurately covers different power spectra shapes, including Kaimal, Korean, and other power spectrum densities. The Wind action’s time performance (all options) has been optimized with a Parallel Computation of EigenModes to achieve higher integration accuracy.

The default setting is to process in parallel as many Eigenmodes as the number of CPU cores the workstation on which RM Bridge is run has. For example, on a machine with four cores, 4 Eigenmodes will be processed simultaneously. Hardware equipped with Intel Hyper-Threading doubles the processing power to 8 virtual cores / 8 threads of execution.

By removing the software limitation of processing modes in a serial manner, the user is now free to lower the time spent on Wind analysis simply by employing more powerful computing hardware in terms of CPU cores.

The principle “More cores, faster analysis” is now unlocked.

5. Error Corrections The following errors have been corrected:

There was an issue in integration points distribution with refined method calculation in dynamic Wind in the frequency domain. This issue has been corrected as part of enhancement #4 above.

The issue with storing and restoring load cases from load case (.lc) files has been fixed.

In FEM temperature analysis, there was an issue in total results on composite parts which were getting clobbered by primary results. This issue has been fixed for primary temperature loads on fem composite models.

The issue of DoRep action with excel output has been fixed. The issue of plotting tendons with the command "Pltndgm" and use Rmset

has been corrected. For new inserted segments, variables and formulas are being copied, too. The number of characters for the stress point name was increased in *lst

output files. There was an issue in cross-section boundary meshing after reading *.tcl files.

This issue has been corrected. The tendon update issue with the same geometry points definiton and new

cross-section information has been fixed.
