LEAP Bridge Enterprise V8i (SELECTseries 6) v13.00.00.68 incorporates the following enhancements and fixes to itself and its component programs:

LEAP Bridge v13.00.00.68

Enhancements:

• Several enhancements to the ABC Wizard including new options for
  • Combined footing definition
  • Advanced definition of girders, different beam types in spans
  • Advanced definition of girders, different start and end distances in a span
  • Advanced definition of piles and customization of x and z for layout and batter direction specification, for both abutments and intermediate piers.
  • Program now allows user to specify unit prices for materials and computes and reports estimated quantities and cost for bridge.
  • On 3D model export to DGN, EC properties (dimensions, IDs, material properties) are written out as well.
  • Introduced a new bridge type cast-in-site post tensioned I-girder bridge for the India code option.
  • New workflow introduced so that after changes are made in GEOMATH and the model is updated to LEAP Bridge, users can still go into CONSPAN and RCPIER and make geometry changes.

 

Fixes:

• Span beam seat elevation report now displays the elevation at the top of the seat rather than bottom at cap level.
• Several 3D graphics issues have been fixed including incorrect section variation orientation for skewed flat slab and box girder bridges.
• Fixed issues with integral pier elevation computation when superstructure has a cross-slope defined.
• Fixed issue with bridge deck start and end when viewed in Geomath for offset bridges on curved alignments.
• Fixed issue with editing of bridge element names directly in tree view on the Geometry tab.
• Schematic curbs are drawn in bridge section views, even when curb is less than 1.5 ft.
• Corrected H-pile orientation in 3D and 2D view drawings.

 

LEAP CONSPAN v13.00.00.68

Enhancements:

• CONSPAN now offers a new option to consider sacrificial deck thickness in computation of LRFD live load distribution factors.
• CONSPAN offers an option to allow users to not include the reduction of live load distribution factors for moment in longitudinal beams on skewed supports.
• Load rating summary table now reports prestressing strand tension (PSStT) if selected for rating analysis. The computation of PSStT has been modified to follow the procedures of the MBE, section A3.13.4.2.b.
• For Canada code option, comprehensive load evaluation of prestressed girders per Chapter 14 of CSA S6-06 is now offered.
• New unified Help file replaces the previous user manual Volume 1.

 

Fixes:

• Rotations due to live loads were incorrect and have been fixed.
• Fixed the following Vertical Shear issue: When the option to use Simplified Shear procedure (LRFD article 5.8.3.4.3) was used, the design shear Vu was incorrectly using the shear corresponding to the maximum moment rather than the maximum shear.
• Live load distribution factor for multi-stemmed beams: When using Lever Rule the distribution factors were computed incorrectly by considering the distance from the edge of curb to the center of exterior web rather than to the center of the beam. This issue is now fixed.

• Shear Rating factors computed with the FLDOT option for counting shear stirrups across failure plane turned on, and simultaneously the simplified shear design procedure was used were incorrect. This issue is now fixed.
• The connection from CONSPAN to AASHTOware Virtis/Opis v6.3 was rewritten to make it more stable and easier to update in to newer versions in future releases.
• A new warning message highlighting current program assumptions on flared (or non parallel beam arrangement) is now displayed when the run analysis button is pressed.
• For Canada code option, minor bug fixes include
  • Deflection computation has been updated to use distribution factor for Moment, and considers the dynamic allowance for Truck.
  • Horizontal shear required vs. provided graph was using incorrect unit conversion, and was corrected.
  • Dead Load reactions were not multiplied by ULS value under ULS printout. Fixed now.

 

LEAP CONBOX v13.00.00.68

Enhancements:

• Post-tensioned I-girder bridge for CONBOX India:
  • Simply-supported parallel girders on straight alignments
  • Multi-stage post-tensioning
  • Parametric cross-section definition for I-girders
  • Library of cross-sections to choose from
  • End block and taper section definition
  • Elastic shortening, Concrete creep and shrinkage, and steel relaxation losses in post-tensioning tendons per IRC
  • Deflection calculation, stress checks, and shear and moment capacity calculations per IRC

Fixes:

• For CONBOX US: Corrected values of a, c, b, bw reported in the detailed moment capacity report for the California option.
• For CONBOX India: Resolved discrepancy in the permissible shear stress values shown in Design Parameters and the ones actually used in design.

 

 

LEAP RC-PIER v13. 00.00.68

Enhancements for US, Canada, and India: Flexural design is now offered at user-defined points of interest along pier columns and drilled shafts. Export selected analytical results of all load combinations with or without P-Delta effect to spreadsheet. Reformatted the pile reaction and combined footing reports for clarity. Option to reset loads and load combinations when changes to model are made. Option to retain existing live load cases when the impact factors are changed. Load effects are now calculated and reported at bottom of footing for the spread footing option. Single row of piles can now be designed as reinforced concrete members. Improved graphic view of shear reinforcement in pier columns.   Additional enhancements for US: New features for California Option: Out-of-plane load distribution. Creep and shrinkage load generation. Auto generation of wind pressure on structures as per FDOT Structures Design Guidelines. To activate this feature select WS as per FDOT SDG 2.4 under Loads tab. Optimized the P-Delta analysis to substantially reduce execution time.   Additional enhancement for Canada: Auto-generation of vertical wind load.   Additional enhancement for India: New workflow for steel reinforcement in column auto design.   Following issues were fixed for US, Canada, and India: Incorrect load effects were calculated in combined pile footing and combined spread footing. Incorrect calculation of exposure height of substructure in auto generation of wind pressure on structures. Incorrect load factor for the self-weight in combinations not involving DC load. Incorrect moment of inertia reported in the stepped cap design. Incorrect calculation of self-weight of stem wall for abutments. Inconsistent bearing offset for abutments between LEAP Bridge and RC-PIER. Incorrect orientation of H-piles in 3-D graphic view. Displacements and rotations were incorrectly reported under “Show P-Delta Effects” option. Incorrect 3D view of Cap Loads in y-direction. Incorrect 3D view of Column Loads. Incorrect governing load combination for footing design for “User specified maximum soil reaction” or “User specified maximum pile reaction”. Incorrect load effects were used for footing design. Incorrect calculation of CG of pile group for abutment piles with variable spacing.   Additional issues fixed for US: Moment magnification did not work for the footing design. Incorrect load factors of vertical soil pressure load (EV). Incorrect label for the fatigue load combination. Incorrect reactions at intermediate piers under the Integral Abutment option. Vertical soil pressure load (EV) was incorrectly applied in case of multiple spread and pile footings. Load effects were incorrectly combined when EH, EV, or LS load cases were used in design. Incorrect coordinates in footing design report due to inconsistent sign convention between the global and local coordinate systems. Incorrect multiple presence factor for permit live load was used for California option. Truck and lane loads didn’t go together in live load auto-generation for LRFD-California option. Incorrect red flagging in cap and footing design reports. Crash when printing Analysis results for controlling load combinations for abutments.
