AASHTOWare Bridge Design employs the same database and graphical user interface as AASHTOWare Bridge Rating, and has the same application program interface for third-party add-on modules. (See AASHTOWare Bridge Rating section on Architectural Support for Third-Party Customizations and Add-Ons.) AASHTOWare Bridge Design includes an LRFD analysis engine. This analysis engine supports the current analysis needs of the software and designers can run multiple analysis programs from one definition of a bridge. A new design tool for prestressed concrete beams was released in 2016. The overall framework includes libraries of beam shapes, vehicles, materials, and the basic capabilities required to analyze and design a single prestressed concrete beam. A future release will add the capability to design all beams in a cross-section. The user can describe the overall bridge geometry (framing plan) that includes multiple prestressed concrete beams. This is the “System” definition in AASHTOWare Bridge Design and AASHTOWare Bridge Rating. The tool will compute live load distribution factors and both dead loads and live loads. The user specifies parameters, such as a range for the beam depth, and the tool will determine a strand pattern for either harped strands or debonded strands as specified that satisfies the AASHTO LRFD specification. The user is presented with one or more beam designs that satisfy the specification. Bridge Configurations and Capabilities Superstructure configurations and capabilities include:

Common Database and User Interface Since AASHTOWare Bridge Design and AASHTOWare Bridge Rating share the same database, all structural models built with AASHTOWare Bridge Design will automatically be available for analysis in AASHTOWare Bridge Rating. Output Reporting Features AASHTOWare Bridge Design provides a sophisticated set of output reports to help the designer understand the performance of a new bridge. A tree-structured graphical representation of the LRFD specification indicates whether each article is passed or failed and provides access to the detailed calculations for the bridge as well as the specification text. A suite of X-Y plots shows moments, shears, deflections, and other valuable information. Substructures AASHTOWare Bridge Design for LRFD substructures was incorporated into the product line in April 2008 (release 6.0) and later incorporated into the AASHTOWare Bridge Design and Rating software as a standard feature in release 6.1. AASHTOWare Bridge Design substructure provides for the analysis and specification-checking for common pier types including wall, hammerhead and multi-column bents. If funding permits other substructure types, including abutments, may be added.

AASHTOWare Bridge Rating is AASHTOWare’s product for bridge load rating, featuring state-of-the-art graphical tools to speed preparation of the data and application of the results. Using a newly developed AASHTO module as its analytical engine for load and resistance factor rating (LRFR), load factor rating (LFR) and allowable stress rating (ASR), Bridge Rating provides an integrated database where rating inputs and outputs can readily be stored, reviewed and re-used. Through this database and the application-independent user interface, a user may provide a 3-dimensional description of a bridge superstructure. This bridge data can then be used by a variety of line-girder, 2-D or 3-D analysis packages, permit/routing systems and other third-party produced applications.

Bridge Load Rating and Permit Vehicle Analysis Database Having all of its data in a standardized accessible form makes it economical to build powerful new features for management of the load rating process and for support of routine business activities such as policy development and overload permit application review. For example, bridges along a route can be placed into folders, where an entire route can be rated for a permit vehicle in a single step. Permit analysis includes sophisticated three-dimensional analysis to consider load effects due to a specific vehicle traveling along a user-defined path on a structure. AASHTOWare Bridge Rating complies with corporate database management standards by supporting the widely used Oracle and Microsoft SQL Server database managers, including their data sharing and security features. A new rating tool was released in 2016. The tool added a new process to AASHTOWare Bridge Rating that is capable of very quickly computing load ratings. To the extent possible, data required for computing a load rating will be computed and preserved in advance of the request for a load rating. This process greatly reduces the amount of computations that must be performed to produce a load rating when one is requested. A majority of the computations will be performed in advance of the request, pre-computing the data necessary for computing a load rating. This technique implemented in the rating tool allows AASHTOWare Bridge Rating users to quickly compute load ratings based on a vehicle description and a list of bridges. The rating tool is not a permitting system. It will not select a route or generate a list of bridges along a route. It will be able to utilize a list of bridges selected by the user and rate those bridges that are in the rating repository. There is a software interface for the rating tool that enables it to be called from other systems including permitting systems. Graphical Features and Customizable Libraries AASHTOWare Bridge Rating contains a host of features to make load rating as easy as possible. Libraries of standard and user-defined vehicles, loads, steel and pre-stressed shapes, load and resistance factors, materials, parapets, and other bridge components allow bridge models to be built quickly in a drag-and-drop manner. All or part of a bridge can quickly be copied to another bridge. As a bridge model is constructed, a graphical schematic framing plan, elevation view, cross-section view, and other schematics provide feedback and make common types of errors apparent. Import and Rating Features As the successor to the Bridge Analysis and Rating Systems (BARS), AASHTOWare Bridge Rating can import existing BARS data files. Existing BRASS and BAR7 data files are also supported by the import feature. AASHTOWare Bridge Rating provides flexure and shear ratings, computes dead loads and distribution factors if they are not manually input, and analyzes deteriorated sections. Data can be provided in either cross-section or schedule-based forms. Architectural Support for Third-Party Customization and Add-ons Since the structural model of a bridge in a database can be complex, AASHTOWare Bridge Design and Rating provides a simplified object model that ties the modules of the system together and makes the software open to expansion by sophisticated users and third-party developers. The AASHTOWare Bridge Design and Rating .NET Application Program Interface makes it possible to access the system’s data and functionality from many commercial software packages, including Visual Basic^®, Excel^®, AutoCAD^®, and even Microsoft Word^®. AASHTO encourages third-party developers to market add-on features, which enhance the core capabilities of the system.

AASHTOWare Bridge Management supports the entire bridge management cycle, and is capable of maintenance tracking and federal reporting. The software integrates the objectives of public safety and risk reduction, user convenience, and preservation of investment to produce budgetary, maintenance, and program policies. It provides a systematic procedure for the allocation of resources to the preservation and improvement of the bridges in a network, by considering both the costs and benefits of maintenance policies versus investments in improvements or replacements. AASHTOWare Bridge Management supports the collection of inspection data based on the AASHTO Manual for Bridge Element Inspection, and provides the user with a well-organized and intuitive user experience. The software continues to be improved and expanded with each release of AASHTOWare Bridge Management. The system consists of a set of modules, each of which is designed to provide the user with the informational display, options and actions relevant to the module’s particular function. The AASHTOWare Bridge Management framework is being expanded to support multi-asset data collection and storage. The current version of AASHTOWare Bridge Management includes capabilities to collect and report tunnel inspection data in addition to bridges. Agencies licensing AASHTOWare Bridge Management in FY2021 will receive the latest version of AASHTOWare Bridge Management and subsequent versions that are released during the fiscal year. As a web-based system, AASHTOWare Bridge Management supports asset management, inventory, and inspection data through a web server either hosted on an agency’s intranet or internet connections or hosted remotely through an agreement with the AASHTOWare Bridge Management contractor (Mayvue). Selecting the local installation or the hosted, SaaS service, does not change the features or capabilities of the platform. AASHTOWare Bridge Management provides a full suite of out-of-the-box reports designed specifically to support bridge management needs. Reporting is facilitated through Crystal Reports, which allows for new report development and customization of provided reports. With the purchase of each Agency’s AASHTOWare Bridge Management software license, each Agency has a developer license to Crystal Reports 2013. To obtain a license, each Agency should send an email to the contractor and they will provide the license key. Support for AASHTOWare Bridge Management release 5.2.1 and earlier ceased June 30, 2019. Agencies interested in utilizing a SaaS solution should contact Mayvue for additional information. AASHTOWare Bridge Management software licensees are able to purchase optional add-on modules to enhance the overall capabilities of the system. Add-on modules and hosting services may be ordered via AASHTO Hosting and Add-On (HAO) Service Units. AASHTOWare Bridge Management supports Oracle and Microsoft SQL Server databases. Licensees should confirm support for specific versions or releases of these databases with Mayvue.
