Post-tensioned Concrete Multi-cell Box LRFR Rating 5 LRFR User-defined box cross sections Line girder analysis, full box along with web-lines Integral with pier

Permit Analysis with Adjacent Lane Traffic Design review and rating analyses User-defined adjacent vehicle LL factor Live load distribution factor approach in LRFD Article

Steel Girder Superstructure Continuous for Live Load Rating 7

Reinforced Concrete Slab System Integral with Pier 8 RC slab system definition is assigned to the superstructure and the pier will recognize the slab structure type is a RC slab system integral with the pier

Curved Girder Enhancements Live load analysis of bottom flange lateral bracings Reuse dead load analysis results and influence surfaces Additional finite element nodes for modeling diaphragm Display bearing of curve at supports in Superstructure Alternative window 3D Model Viewer enhancements 9

User Group Top Enhancements from Aug Meeting 10

Specification Updates AASHTO LRFD Specification updates (7th Edition) AASHTO Manual for Bridge Evaluation Specification updates (2nd Edition with 2014 Interim) 11

12 System is nearly 15 years old – first released April 1999 Software tools for development have significantly changed and improved User expectations have matured Hardware has improved, need to take full advantage of new hardware capabilities (e.g. multi-threading, 64 bit, etc.)

13 When development started Windows 95 or NT were common and were replacing Windows 3.11 Needed a 386DX processor Needed minimum 4 MB RAM (8 MB recommended) Hard drives in the MB size common There have been 7 versions of Windows O/S since we started Windows 98, 2000, ME, XP, Vista, 7, and 8

14 Currently Windows 7 or 8 – 64 Bit Memory – 16 to 32 GB common Hard drives in 1 or 2 TB common, very fast solid state drives becoming common in GB range Tremendous changes in OS and Hardware over the last years

15 Migration to a new architecture using the latest development tools  Improve analysis performance by taking advantage of the latest hardware and software advances – multi-threading  Improve the user interface - easier to use for beginners without losing modeling flexibility for advanced users  Improve reporting capabilities  Reduce maintenance costs  Reduce implementation time for new features

16 Architecture Design is Underway  Conducted a workshop to identify the requirements that drive the architecture design  Currently working on the high-level architecture design  Evaluating the user-interface requirements  Work has started on the modernization of the finite element engine  Solicitation for funding early next year (2015)

17 What is under development for 6.7.0? User Group Enhancements Gusset Plate Rating Splice Analysis Cut top strand for PS Concrete Beams Splayed Girder – Distribution Factor RC Slab System – Substructure Culvert – Shear General procedure Exposure Factor - Culvert

18 LRFR for Floor Systems Analysis Template vehicle export AISC Steel shapes update Steel Plate Girder Design Tool Straight Girder (3D) Modeling Improvements Specifications Update (from 2014 SCOBS meeting) Plus Continued User Support and Maintenance (bug fixes)

19 Design Tool Efforts underway for a PS Design Tool Jeff Olson to discuss further later today
