AASHTOWare Bridge Design & Rating 6.8.4 Released

November 04, 2019

The AASHTOWare Bridge Task Force is pleased to deliver version 6.8.4 of the AASHTOWare Bridge Design (BrD) and AASHTOWare Bridge Rating (BrR) products, as well as the combined Design and Rating product (BrDR). This is the second release that makes the modernized AASHTO analytical engine available, along with the legacy engine. The modernized engine improves on the analysis runtime performance of all structure types and paves the groundwork for future performance optimization.

Version 6.8.4 is the last release of the legacy system as work is nearly completed, with testing underway, on the second phase release of the modernization project – with both scheduled to finished in 2020.  The second phase release will deliver the complete modernized system, which significantly upgrades core technology to a modern software architecture that can use current and future hardware plus connect with the latest software development technologies. In addition to the modernized AASHTO analytical engine, the modernized system comes with an improved and simplified user interface that is easier to use for beginners without losing modelling flexibility and robustness for advanced users.

As the AASHTOWare Bridge Design and Rating products continue to undergo significant improvements and enhancements with each release, the system resource requirements are also increasing. The minimum and recommended hardware and software requirements for memory specified in the AASHTOWare 2020 Catalog and the AASHTOWare Bridge Startup Guide are generally sufficient for girder-line analysis, but they may not be adequate for LFR/LRFD/LRFR three-dimensional analysis of large multi-span bridges. Those memory resource requirements are dependent on the size of the model, the type of the bridge, and the complexity of the analysis.

The 64-bit version of this release is being made available for download, while the 32-bit version and DVD of this release may be requested by sending a request to BrDR@mbakerintl.com.

For licensees of Bridge Design, Bridge Rating, and Bridge Management, please contact BrDR@mbakerintl.com for information on integrating them all together.

The Task Force extends its sincere appreciation for your continued support as we work to provide you with a modernized system. We encourage your feedback so we can provide you with the necessary features for improving the productivity of your staff and the quality of their work. The appropriate system download package (with Bridge Design, Bridge Rating, or both) is provided in accordance with your AASHTO license agreement. Installation instructions are provided within the AASHTOWare Bridge Startup Guide (AASHTOWare Bridge Startup Guide.chm within the download package or on the DVD).
