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.

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

• 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

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, fci, fc
• Increased user control
• Effective web width
• Revision for LRFD-California option
• Automatic tendon definitions for hinged spans

RC-PIER
22
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.

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

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
