Eriksson Culvert is the most advanced engineering software for precast and cast-in-place box culverts, seamlessly combining the functionality of a state-of-the-art structural analysis engine with fully automatic design and analysis capabilities. Integration of the critical design tasks into one system means you get superior productivity and flexibility with improved quality control.


In auto design mode, Eriksson Culvert quickly analyzes and designs wall thicknesses and reinforcement sizes and spacing. A comprehensive reinforcement schedule containing rebar and mesh is produced, complete with all bar dimensions and bends. LRFD, Standard, AREMA, and CHBDC specifications are supported, as well as, both US customary and metric units. 


The highly graphical user interface provides multiple views to render the design and present the results. Complete details of the design along with detailed calculations are provided. Powerful graphics show all rebar rendered in true 3D and a user-customizable truck library is included in the sophisticated live load capabilities.

Software can be installed on a server. 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. 


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