Capabilities

  • Analyze, design, and rate bridges

    • Streamline bridge modeling, analysis, and load-rating for both existing and new bridges with an integrated toolset. Leverage various international design code specifications and rating methodologies for verification.

  • Capture roadway geometry and topography

    • Reuse civil data obtained directly from Bentley road products such as GEOPAK, Bentley InRoads, or MXROAD, and import roadway information and ground data from LandXML files.

  • Coordinate multi-discipline bridge teams

    • Exchange project information including bridge geometry, materials, loads, prestressing strand pattern, and shear reinforcement to improve decision making. Streamline engineering content management with real-time collaboration and share, reuse, and repurpose data throughout the bridge lifecycle to minimize risk of design error and construction issues.

  • Design and analyze steel bridges

    • Model, design, analyze, and load-rate and optimize steel I-girder and tub-girder bridges using powerful analysis techniques such as Finite Element Modeling (FEM) and Response Spectrum Analysis, according to AASHTO LRFD Bridge Design specifications.

  • Design and analyze superstructures and substructures

    • Use a synthesis of geometric modeling, substructure and superstructure analysis, and design in a single information-rich environment to benefit from a comprehensive bridge model.

  • Generate bridge project deliverables

    • Generate detailed reports. Create 3D models and 2D drawings for sections, elevations, and framing plans.

  • Sequence construction and phasing

    • Investigate the different stages in stage-wise construction – comparing results, detecting the relevant states, and producing result envelopes for proof checking. Account for creep, shrinkage, and relaxation and solve problems before construction begins.

  • Visualize bridge designs

    • Experience instantaneous 3D visualization of the bridge superstructure and substructure. Visualize designs and rapidly verify modeling input as you work. View in-profile, elevation, and cross-section views with solid and transparent view options to help explore areas with complex geometry.
