@MichaelOcampo1104 welcome to Blueprints! Thank you for your contribution! I will have a look to it asap

Hi @MichaelOcampo1104,
Thank you for contributing to Blueprints!

Enevthough the implementation of tables is not standardized within Blueprints, it has some considerations. We generally allow subclassing from Formula if it fits the purpose. In case of Table 5.2, I don't think it is the appropriate choice. Since Table 5.2 is rather complex, we need to come up with a propper structure for it to facilitate all the possible use-cases and cover all the information provided in the code. And above all, provide a clear and intuitive API for our users.

I have opened issue #792. Please feel free to discuss your ideas on what architecture you would choose for the implementation. Once we have consensus, you can assign it to yourself and start working on the PR.

For inspiration, you can have a look at the tables implemented in chapter 4 of EN1992-1-1.

Best of luck! 🚀

i kinda like the approach that has been used in this PR. when looking at the table.. its not really a table, its just formatted as is. Basically table 5.1 part 1 is just 3 (series of) equations using c, t, alpha and fy as input variables, one of which is featured in this PR. It would need clarification that it only does the Internal compression parts though, and im not sure where the current equations for alpha and psi come from

@GerjanDorgelo , Yes, the way I approach Table 5.2 Sheet 1/3 is provide it with 3 equation instead of a formal table., this approach can apply similarly for Sheet 2 and 3, as for the alpha and psi , these values are derived from the equilibrium of stress distribution as illustrated in Table 5.2 Sheet1/3
