About LARSA, Inc.

LARSA, Inc. develops advanced software for the analysis and design of bridges and structures based on the finite element method. By coupling structural analysis and design with the latest computing technology, LARSA 4D has become the most reliable software of its kind for segmental, cable-stayed, suspension, steel girder and other bridge forms, as well as other structures requiring geometric or material nonlinearity, complex three-dimensional geometry, or advanced staged construction analysis.

LARSA, Inc. is privately owned and based in New York, with all its software development and product supports services conducted in-house.

Our History

Committed to pushing the envelope of structural analysis software, LARSA 4D products have led the market with many industry firsts.

  • 1980’s - 1990's

    LARSA is the first PC-based structural analysis software supporting geometric nonlinearity and plastic pushover analysis with sparse solver technology for Microsoft Windows.

  • 2000’s

    LARSA 4D leads the industry as the first to offer robust time-dependent staged construction analysis for post-tension concrete segmental and cable stay bridges.

  • 2010’s

    LARSA 4D's "Features on Demand" is the 1st tool to deliver custom software updates to end-users in real-time. The LARSA 4D Steel Bridge Module provides new capabilities for refined modeling and rating of complex steel girder bridges.

  • 2020

    LARSA 4D remains at the forefront of modern engineering with new analysis capabilities for high-speed rail, advanced geometric nonlinearity, and rapid object-based modeling techniques for BIM-ready bridges.
