These components were conceived for use in prestressed concrete construction and are especially suited for the design of bridges, containers, and prestressed flat slabs (free tendon layout) with or without bond. The basic principle here is a 3D, element-independent tendon guide with load processing based on cubical splines. The editing takes place in the graphical user interface, where the whole process can be monitored visually at all times.
	Together with the prestressed concrete checks according to DIN 1045-1, ÖNORM B 4750 and B 4753, the module complements the configuration level FEM 3D, bringing you a flexible and powerful comprehensive solution for sophisticated constructive engineering tasks. The Bridge Checks According to DIN Technical Report and EN 1992-2 complement the program suite, making it into an extremely powerful tool for bridge construction.
