10. GEOMATH

11. 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.

12. Geometry Modifications…e.g. Flared Girders

13. CONSPAN

14. 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.

17. CONBOX

18. 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

21. 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.
