# RC design of a T-shaped beam subjected to biaxial bending and normal force

In this example we verify the accuracy of WeStatiX for the calculation of a cantilever beam subjected to biaxial bending and axial force. The cross section is T-shaped.

You can start immediately the calculation using the T beam model available in WeStatiX: in the picture below you can see it and check the magnitude of the applied loads.

In the following picture you can see how the cross section shape has been defined.

The following the material parameters have been used for the analysis.

The force applied on the free node is defined as in the following image.

Finally, here is how you can set the parameters for the reinforced concrete design.

Then you can start the calculation: here we focus on the RC design, so read the ULS total reinforcement area. It is $$A_{s,tot}= 20,36 cm^2$$.

When you calculate the reinforcement area for a generic cross-section, you need to remember that WeStatiX consider it as equally distributed throughout the corners of the section.

In order to verify the solution, you can compare it with the one obtained with the software VCA SLU – Gelfi. In the screenshot you can see how we set the same problem parameters.

As you can see from the resistance field below, the section is verified. In fact, the blue point representing the design internal forces is located very close to the interaction diagram border (maximum bearing capacity).
