Standards and codes are important. Where do you plan your project and what do you have to pay attention to? When it comes to international standards, the Dlubal programs are reliable companions for customers from all over the world. You will find numerous standards integrated in RFEM and RSTAB, whereby the corresponding add-ons allow you to design steel, reinforced concrete, and timber structures. Here you will find an overview of the standards available in the programs for the respective countries.
