Product Data Sheet LARS Bridge™ Integrated Bridge Load-Rating Analysis, Modeling, and Editing LARS Bridge brings a streamlined process to bridge load-rating modeling and analysis – for both existing and planned bridges. The software handles most common single- or continuousspan bridge types. LARS Bridge provides an integrated toolset for efficient graphical modeling, editing, and load-rating analysis. System Flexibility As the core software in the LARS Bridge family, LARS Bridge is complemented by a set of specialized modules that extend the rating functionality. Users are able to enhance the system to perform complex truss bridge rating, multiple bridge rating, data management, and data checking. Industry Compatibility Member definition for a continuous truss Additionally, LARS Bridge is an AASHTO-approved load rating engine that runs within Virtis, offering Virtis users an alternative, proven rating engine. The ability to use LARS Bridge inside or outside of Virtis brings an additional level of workflow flexibility in how LARS Bridge can be deployed by organizations. Direct Integration with Routing and Permitting LARS Bridge delivers broad industry compatibility and fits well with the overall bridge maintenance workflow. The software conforms to the latest AASHTO Bridge Specifications for: • LRFD – Load and Resistance Factor Design • LFD – Load Factor Design • ASD – Allowable Stress Design Using these bridge design specifications and the AASHTO Manual for Bridge Evaluation, LARS Bridge performs up-to-date LRFR (Load and Resistance Factor Rating), LFR (Load Factor Rating), and ASR (Allowable Stress Rating) bridge ratings. Bridges analyzed with LARS Bridge can be used directly by the Bentley SUPERLOAD live-load bridge analysis process for oversize/overweight routing and permitting. LARS Bridge Modules The LARS Bridge system offers several add-on modules that extend the functionality of the core LARS Bridge software: • LARS Complex Truss: This module provides the capability to load rate complex truss bridges that contain geometry that cannot be modeled using the predefined panel types provided in LARS Bridge. Graphical display of analysis results • LARS Connector: This module provides a connection to the AASHTO BRIDGEWare database to directly extract Virtis/ Opis bridge models into LARS Bridge format. Graphical Modeling and Analysis Tools Member definition for continuous composite steel member The available LARS Connector module allows LARS Bridge to utilize complete bridge data from the AASHTO BRIDGEWare database, sourced by AASHTOWare Virtis and Opis software. LARS Bridge also works directly with retired-format AASHTO BARS (Bridge Analysis and Rating System) files, extending the usefulness of legacy bridge data. • LARS RouteRunner: This module provides the ability to perform a quick permit weight analysis for any number of bridges and a permit vehicle. Another option provides the ability to perform inventory, operating and/or posting rating analysis for up to 10 trucks each, for a total of 30 trucks. All reporting is done using Microsoft Excel. LARS Bridge is used to model and analyze the most common bridge types. An easy-to-use graphical interface enables bridge engineers to quickly and efficiently enter all bridge data needed for load rating analysis. Graphical tools display a variety of analysis results generated by the analytical engine: moment and shear envelopes, available capacity for live load, actual live load plus impact, dead load, and superimposed dead load. LARS Bridge displays influence lines for moment and shear at checkpoints along the structure. Engineers can choose from numerous report types to provide tabular, detail, and summary results at any location within the member. • LARS Manager: This module provides data management functions for LARS Bridge data. All bridge models are available in a simple-to-use interface with fingertip access. • LARS Checker: This module performs basic checks of LARS Bridge data and is used most often after bridge information is imported from Virtis or BARS.
