New Update LARS Bridge v5.00.06.09 available on SELECT Server

General

  1. Fix for LRFR live load various distribution factor values were defined in various spans of continuous structures.

       2.   Fix for ASD/LFD/LRFR live load symmetry.  A larger live load value was sometimes computed.  Changes have been made to the lane live load computation which will result in a slight increase or decrease of the previously computed value.

       3.   Fix in Echo.lis when reporting nonstandard truck axle loading.

       4.   Fix in Echo.lis for LRFD LLDF member id.

       5.   Adjusted tabular summary report for when requesting critical summary for one design method.

       6.   Adjusted tabular summary report  and set the capacity equal to zero for all reports when a -999 rating factor is computed.

       7.   Adjusted live load logic to assure transverse loadings include both wheel lines of a truck on floor beams.

       8.   Corrected critical summary report for LRFR when multi-lane and single results are for different members.

       9.   Corrected interpolation of moment and shear values for LRFR member

     10.   Corrected an issue where Stage I continuous dead load were not used

 

Reinforced Concrete

  1. Added a customization option to compute the ASD/LFD critical shear location from the face of the support.

            

       2.   Corrected an issue with LRFR RC Service.  Service values will only be output for permit vehicles.

       3.   Corrected an issue with the computation of “c” for LRFR T-sections.

       4.   Corrected an issue where continuous members didn’t run when the face of support option was turned on.

       5.   Adjusted the maximum number of sections available for haunched sections in LARS analysis.

Prestressed Concrete

       1.   Added a customization option for ignore RC formulation for negative shear computations

             

      2.   Added a customization option to compute the ASD/LFD critical shear location from the face of the support.

            

     3.   Adjusted the interpolation of prestressing reinforcement for draped strands, smaller values were used previously.

     4.   Set the size of debonded strands equal to the prestressed strands selected.

     5.   Corrected an issue where continuous members didn’t run when the face of support option was turned on.

 

Structure Steel

     1.   Report LRFR nominal resistance as a negative nominal resistance for top positive bending and positive nominal resistance for bottom negative bending when the resistance computed is not adequate for the load demand.

     2.   Changes in the Cb computation may result in larger values for Cb and may increase in the moment capacity.

     3.   Change sign of M1/Mu for compact Lb/ry qualification.  The sign was incorrect for bending.  The sign convention was correct for Rb computation.

 

Timber

      1.   Fix when 2nd distribution factor option first for Inventory and second for Operating & Posting is selected.

 

Truss

      1.   Fix for K-panel trusses for vertical members.  The vertical was selected as sub-divided in some cases.

      2.   Adjusted location of front wheel output.
