Eriksson Culvert

A Better Way to Design Precast/Prestressed Box Culverts

Eriksson Culvert is a high-performance Windows-based program that seamlessly combines the functionality of a state-of-the-art structural analysis engine with both fully-automatic design and analysis capabilities. Integration of the critical design tasks into one system means you get superior productivity and flexibility and improved quality control.
Precast or CIP 4-sided, 3-sided, and V-bottom culverts can be handled. In auto design mode, Eriksson Culvert quickly analyzes and designs wall thicknesses and reinforcement sizes and spacing. Reinforcement can be rebar or WWF (mesh). For rebar, a comprehensive reinforcement schedule is produced, complete with all bar dimensions and bends. Both AASHTO Standard and LRFD/LRFR Specifications are supported.
The highly-graphical user interface provides multiple views to render the design and present the results. Complete details of the design are provided, along with detailed calculations. Powerful graphics show all rebar rendered in true 3D. Sophisticated live load capabilities include a user-customizable truck library.

    Single User License


    Software can be installed on a single workstation. This license is tied to the workstation's hardware and cannot be shared with other users, and can only be moved to another machine after contacting us. 

    This license is most suitable for mobile computers or a single user/workstation setup.

    Floating Network License


    Software can be installed on a local area network. The license server keeps track of how many licenses are in use at one time. When an application using network licensing starts, it first checks to see if a network license is available to use. If so, a license is then checked out from the pool of licenses. When a user exits the application, the license gets checked back into the pool making it available to other users. Additional seats can be added for $1,495/year.

    This license is most suitable for companies with many (non-concurrent) users.
