r7.04.06 Automated tie rod method for the calculation of reinforcement

Summary:

This document presents the post-treatment macro command CALC_BT, an alternative aid using a numerical model for the application of the tie rod method that is used to calculate the reinforcement of a reinforced concrete structural element. This method consists in finding a mesh embedded in the structure whose reinforcement we want to calculate based on a calculation on homogeneous material (concrete). The connecting rods of this mesh are made of concrete, the tie rods are made of steel.
