LEAP Bridge V8i (SELECTseries 2) maintenance release v10.00.02.19 now available on SELECT

LEAP Bridge v8i (SELECTseries 2) v10.00.02 is a maintenance release and incorporates the following fixes to itself and its component programs:

LEAP Bridge v10.00.02

Fixes:

  • Fixed an error in LEAP Bridge, where if the user selects EXIT option in CONBOX, LEAP Bridge was closing.
  • Automatically minimize LEAP Bridge, when a component application is minimized.
  • Automatic bearing location algorithm now considers bottom width of box beams.
  • Fixed an error on update from CONBOX where the support elevation wasn’t computed correctly for models with align POB greater than 0.
  • When using ABC Wizard to create integral cap pier, elevation was always being set to 100 ft rather than considering elevation from profile.
  • Importing ground using LandXML in GEOMATH was causing the superstructure to disappear when going back to LEAP Bridge. This error is now fixed.
  • For bridges offset from alignments, pier stations in LEAP Bridge are defined by drawing a normal from the alignment to the intersection of half the pier length and pier centerline. In GEOMATH the pier layout for such offset bridges uses a reference point at the intersection of the pier centerline and alignment or roadway. Please note these two stations are typically different for offset bridges – the one in LEAP Bridge refers to the center of the pier and the other in GEOMATH only locates a reference point on the alignment for the purpose of the pier layout.
  • Fixed an error in ABC Wizard, for multiple bridge definition, where some user input values for box girders were being reset to default/initial values.

LEAP CONSPAN v10.00.02

Fixes:

  • On the export to DXF option for graphics, an incorrect scaling factor has been fixed.
  • For LRFD design,  h modifiers  were not being applied to shear and this has been fixed.
  • Fixed an error in deck slab design, where CONSPAN was showing the Area of Steel as zero in printout, ignoring the user input area of steel.
  • Corrected an error in the graphs for Av/s-required vs. provided
  • In deck slab design routines, the calculation of effective depth, d and dc, and area of steel were reported incorrectly and are now fixed.
  • Corrections were made in the Permit Load Rating for Shear, and the results are now verified to be correct.

LEAP RC-PIER v10.00.02

Fixes:                                      

  • When the pressure was applied on the columns, program was not converting the load correctly to linear load producing erroneous P-delta results. The issue was only applicable when P-delta analysis option was selected. This is now corrected.
  • When Dead load or live load load was generated using continuous beam option, program was getting terminated abruptly. This is now fixed.
  • For the integral pier, column interaction diagram was not drawn. Now, program shows the generated interaction diagram.
  • For skewed bridges, when reaction from superstructure program, CONSPAN, was imported in standalone RC-PIER, it was incorrectly showing cap length as bridge width. This is now corrected.
  • For isolated footings, even though hook was defined for both ends, program was assigning the hook only on one side. This is corrected now.
  • In some cases, RC-PIER was reporting incorrect abutment elevations when the data was read from LEAP Bridge. This is fixed and program now shows the correct elevation.

LEAP CONBOX v10.00.02

Fixes:

The following issues have been fixed:

  • The Point of Interest (POI) locations used to change when the same stirrup spacing was input.
  • Axial forces and horizontal reactions did not get zeroed out for Custom Live Load.
  • Distribution Factors for the girder-by-girder analysis for Box bridges were incorrectly calculated as similar to the T-beam bridges.
  • “Run Analysis” button remained grayed out after changing tendon profile.
  • "Add to all combinations" option in the Loads/Analysis tab did not work for Live Load Group.
  • The program crashed while double-clicking on a specific truck in the Locked Library Live Load Groups.
  • In LEAP Bridge Enterprise – India
    • Custom Vehicle could not be added in the Live Load Group.
    • Design Parameters values reported under the Design Tab were inconsistent with those shown under the Design Parameters dialog box.
    • Bridge width input defaulted to the minimum value of 3.35m for T-beam bridges.
    • User Input cross-section properties for girder-by-girder were ignored: program always used auto-computed properties.
  • Addition of diaphragms caused individual girder lengths to be different.

 

LEAP GEOMATH v10.00.02

Fixes:                                      

  • Some minor changes for enhanced LEAP Bridge compatibility.
