We want to reinforce a floor slab of a round vessel radially or tangentially.

Is there a way to not calculate an orthogonal reinforcement but a radial or tangential reinforcement?


To display the results as radial reinforcement, the axes of the FE elements must be aligned. To do this, it is sufficient to align the axis system of the surface to a point (here the center of the circle).

To do this, double-click the surface to be edited and then switch to the "Axes" tab. Here you have various options for aligning the axes.

Select "Axis x Align to Point" and use the graphical selection function to select the center of the circular area. After recalculating the results in RF-CONCRETE Surfaces, the reinforcement is output radially and tangentially.
