LARSA 4D's Steel Bridge Module uses a wizard-like interface to simplify 3D model generation for complex I, box, and tub girder bridges, while providing fully integrated AASHTO compliant code check and load rating tools, along with the ability to move beyond typical grillage analysis to utilize influence surface based live load.
LARSA's Section Composer is a graphical companion tool for modeling arbitrary sections for use in LARSA 4D. Section Composer supports standard, parametric, nonprismatic, and custom shape sections
LARSA 4D BRIDGE pLT is our entry-level package for the analysis and design of bridges, including short-span, pedestrian, and steel girder bridges.
Featuring the unrivaled analysis capaibilities of LARSA's Staged Analysis engine, 4D BRIDGE pLT's user-friendly interface is rapidly becoming the preferred software for curved and skewed I, box, and tub girder bridges. From simple girder projects to complex bridges featuring concentric girders with irregular spacing and variable deck width, BRIDGE pLT provides the complete solution for steel girder bridges.
With LARSA's full elastic element library along with cable elements, LARSA 4D BRIDGE pLT supports the following bridge types:
