u4.42.08 Operator CALC_BT

Summary:

The CALC_BT command makes it possible to automatically create and optimize a Connecting Rods structure based on evol_elas or evol_noli results from 2D modeling in stress or plane deformation (C_ PLAN, D_ PLAN). The aim is to calculate the reinforcement of a concrete structure.

For more details on the method you can consult the documentation [R7.04.06] « Automated tie rod method for the calculation of reinforcement.
