What is New & Changed in LEAP Bridge Enterprise V8i (SELECTseries 2) Release v10.00.01?, May 2011

CONTENTS

  • Edit Roadway Elements such as alignment, profile and cross-section directly in LEAP Bridge
  • Create, save, edit and re-use ABC Data using the ABC datasets dialog.
  • ABC Wizard now allows you to define struts for piers
  • Multiple instances of LEAP Bridge can be now be launched on the same machine
  • Adjust list of bridge objects and watch construction animation sequence
  • Export LEAP Bridge 3D model directly and accurately to DGN, including layers.
  • Exports elements in groups (girders, bearings etc.)
  • Measure dimensions in LEAP Bridge 3D view
  • Customize the printout header with your company information and logo
  • Enhanced 2D views show more detail and dimensions
  • Users can specify rectangular drilled shaft and both 2D and 3D displays are updated

  • 3D image shows Horizontal shear and extension of bars into deck
  • Custom shapes from library are drawn in 3D and 2D views
  • Easily define Tapered pier cap in ABC Wizard
  • Specify Eccentricity of Footing under Abutment
  • ABC Wizard allows input of either skew or bearing angle of piers
  • Shear reinforcement/lateral ties or spirals in Columns now shown in 3D

 

LEAP CONSPAN v10.00.01

Enhancements:

  • ProjectWise integration is now available directly from within CONSPAN. Open, Save and Update files directly from ProjectWise repositories.
  • New module to check lateral beam stability during lifting and transportation.
  • Integrated design status window in strand pattern dialog for increased efficiency.
  • Reduced data file sizes.
  • Improved auto-design strand pattern routines.
  • Schematic representation of live load configuration in library has been added.
  • Option to customize company name and logo in report(output) headers.
  • Specify Rebar in beam, and optionally consider its contribution in Moment Capacity.
  • Report on estimated quantities per Beam including concrete, strands, and stirrups.
  • Dead load Wizard: Now allows users to input additional load values directly into the grid.
  • A GUI enhancement made on the beam tab, allows users to double click any beam to bring up the strand pattern dialog. All beams with a strand pattern defined are marked by a blue dot.

Fixes:

  • Fixed a problem with flared girder geometry definition which in some cases resulted in unreasonably large effective width values.
  • Updates to ensure performance on Windows 7 operating systems.
  • A program crash when editing the allowable stress limit on the beam tab was fixed.

 

LEAP CONBOX v10.00.01

 Enhancements:

  • ProjectWise integration is now available directly from within CONBOX. Open, Save and Update files directly from ProjectWise repositories.
  • Reactions can now be automatically transferred to RC-PIER within LEAP Bridge.
  • Bearings are assumed to be located under each web/girder for the box and T-beam bridges or at 12 in (300 mm) o.c. for slab bridges. The reactions are equally distributed among all bearings.
  • Users can define crash barriers, sidewalks/footpaths, pedestrian railing, and wearing surface. The loads are automatically generated and added to the Loads tree under the Loads/Analysis tab
  • A report on material quantities of concrete, mild steel, and post-tensioning tendon has been added.
  • Numbering for the girders/beams has been added for clarity.
  • Right-click option allows users to add a specific load to all load combinations. Duplicates of a specific load are not allowed in any load combination.
  • Descriptive labels have been added to the allowable stress input boxes in the Design Parameters dialog box for clarity.
  • The design summary shown under the Design Tab and the Load Combination dialog boxes have been enhanced with additional details for clarity.
  • Headers and Footers for the reports are updated to accommodate long file names.
  • To reduce confusion, Stresses and Displacements Reports for the Ultimate/Strength Limit States have been eliminated.

 Fixes:

  • Area of prestressing, Ap, is now equally distributed among all girders in the calculation of shear strength.
  • The user-defined "holes" in the solid slab cross-section are now correctly accounted for. The slab section with the holes is approximated as an equivalent I-section for in the calculation of shear and flexure strengths.
  • The Design Parameters now do not get reset to the default values in the hard-copy printouts or upon re-opening the input files.

Design Parameters dialog box has been revised into a tabbed dialog to reduce clutter and add clarity.

 

LEAP RC-PIER v10.00.01

 Enhancements:

  • ProjectWise integration is now available directly from within RC-PIER. Open, Save and Update files directly from ProjectWise repositories.
  • All loads acting on the piers and abutments are now shown graphically in the 3D view.
  • The limit on the number of iterations for P-Delta analysis has been increased to 30.
  • Pile cap abutments can now be analyzed continuous beams.
  • A customizable reinforcement library now is added.
  • Program now allows users to exclude torsion from shear and torsion design check.
  • Footing definition is now brought in geometry tab, for convenience.
  • Footing design can now be specified to be based on the forces acting at the bottom of the footing. Previously only the forces at the top of the footing were considered.
  • The footing tab is completely redesigned for clarity. Now, the footing design status is instantly updated as users modify footing reinforcement. A new footing tab allows users to define additional loads such as dead load, soil surcharge etc on the footing. These loads are in addition to the loads transferred from columns.
  • In the previous version, lateral resistance was only based on the horizontal component of the axial force in the battered pile. Now, the users can specify direct lateral resistance for the individual pile. Thus, total lateral resistance of one pile is now equal to direct later resistance plus the horizontal component derived from the batter, if any. A consolidated "Lateral Resistance Computation" report is added. This report shows the total lateral load on the footing and the total lateral resistance of all piles in the footing. The report is generated for both maximum and minimum governing load combinations. The bearing definition is now directly read from LEAP Bridge database for prestressed girders (CONSPAN) and for boxes, T-beams, and slabs (CONBOX).
  • Concrete and reinforcement material quantity report has been added.
  • 2D views now display drilled shafts.
  • The A/D Parameters dialog box has been re-designed as a tabbed interface for clarity.

 Fixes:                                      

  • For column with spring bases, P-Delta analysis was generating incorrect results. This is fixed. The improved P-Delta routine is now convergent in all cases including columns with diagonal and/or 6x6 springs.
  • Trapezoidal loads acting on columns were not getting correctly saved. This is fixed.
  • In some instances, when a strut was defined between columns, auto design of column was resulting in a crash. This is now fixed.
  • 2D view of pile cap abutment was showing incorrect bearing locations. This is fixed.
  • If RC-PIER was launched within LEAP Bridge and the file was saved as a standalone RC-PIER file, bearings were not getting saved with the file. This is fixed.
  • In footing design status, the reported sign (+/-) of footing eccentricity in z direction was incorrect. This is fixed.
  • In some cases under the Moment Magnification method, the limit of 100 on the slenderness ratio was not being checked and flagged. This is now corrected.

 

Upgrading from LEAP Bridge Enterprise v10.x

  • Make a backup copy of your modified default libraries (in the /Lib folder) by copying the files to a different location other than the original folder.
  • Run the downloaded setup file.
  • Follow the on-screen instructions and install the program. The program will automatically be installed in the existing LEAP Bridge folder. The existing license key will be transferred automatically to LEAP Bridge v10.00.01 without any further authorization action required by the user.
  • Restore the back-up copies of the libraries (created in step 1 above) to the LEAP Bridge folder.
