Bentley LEAP Bridge Is:

• ONE fully-integrated application

• ONE seamless Geometry, Super and Sub Structure program

• ONE central application for data exchange

• ONE database – one or more bridges

ABC Wizard for Bridge Definition

ABC Wizard – Multiple Bridges

GEOMATH

GEOMATH• GEOMATH is fully parametric

keeping track of critical information

pertinent to each project

component. For example, changes

made in an alignment, profile or

superelevation are reflected in the

final bridge model.

• Reports include geometric design

information on abutments, pier caps

pedestals, beam seats, deck

contours, screed and final deck

elevations at user-specified points

along the span.

• Material quantities, including deck

concrete, haunch build up and deck

reinforcing are automatically

calculated.

Geometry Modifications…e.g. Flared Girders

CONSPAN

CONSPAN• LFD & LRFD Simple and

Continuous Prestressed Beam Design

• Library contains all standard AASHTO girders, bulb tees, box beams, double and single tee, rectangular beams, etc. and users can add customized cross-sections.

• Automatically calculates distribution factors, impact/dynamic allowance factors, allowable stresses, etc.

• Grillage-based option for computing more refined distribution factors for many geometry configurations.

CONSPAN Enhancements in V8i

• Deck Rebar design (Phase 1 - Empirical Method)

• Support AASHTOWARE Virtis/Opis v6.0.0

• Bug Fixes

• Pull (/Jacking Force) and CG method of defining strands

• GUI updates – Updated spreadsheet-type controls in Analysis Tab

• Option to create user library of strand patterns

CONBOX

CONBOX

• LRFD and AASHTO Standard Design and Analysis of Cast-In-Place Post-Tensioned/Reinforced Concrete Box Girder and Cast in Place Concrete Slab Bridges

• You can design using one code and simply toggle to the other code for quick and complete design comparisons. This powerful feature makes your transition to LRFD quick, easy, and cost-effective

Export to DGN

CONBOXEnhancements in V8i

• Shear Design Update– Sections with less than minimum amount of shear reinforcement

– Auto Design

• Face of Support– Optional critical section for design

• Allowable Stresses Terminology– Consistent with AASHTO specs

• Load Combination Definitions– Increased user control

• Minimum P-Jack, f’ci, f’c

– Increased user control

• Effective web width– Revision for LRFD-California option

• Automatic tendon definitions for hinged spans

RC-PIER

RC-PIER• Design of reinforced concrete

bridge substructures and foundations.

• Piers types are multi-column and hammerhead piers with straight, tapered or variable caps, and circular, rectangular (tapered and non-tapered) or drilled-shaft columns.

• Footing types include isolated or combined, supported on either soil or piles.

• Integrated design of cap, biaxial columns, and footings using LFD, LRFD or working stress methods.

• Strut-and-Tie (STM) modeling to obtain optimized structures.

RC-PIEREnhancements in V8i

• Battered Piles– Pile reactions, vertical

– Pile reactions, horizontal

• Abutment Tab– New Module!

– Case 1: Pile Cap Abutment

– Case 2: Stem Wall Abutment• On piles

• On spread footing

Database Exchange

LEAP Bridge is also a central command for data exchange between AASHTO BridgeWARE database and any other LandXML compliant applications:

Leap Bridge Configurations

LEAP Bridge

• Small to medium prestressed/precast and long-span post-tensioned concrete bridges in North America.

• Most widely used solutions for design of concrete bridges in North America: more then 2000 Users in North America, 38 DOTs.

• Increasing interaction with other BrIM products
