In that case I would like you to tell me generally which databases include thin-walled sections so to be able to design it in accordance to EN No, it has to have one of the 'thin walled' section symbols assigned to be verified as the thin walled one. If we use a section that belongs to a database with normal sections but its thickness is thin (less than 3mm) then are we able to design it in accordance to EN even if we select “thin walled sections” when defining the member (in “additional sets member parameters”)?

What matters is that it has got all necessary cross sectional properties and the supported section symbol assigned. No, the section can be from any predefined section database or created as a parametric one. To help I'm attaching the documents that show the symbols for both hot rolled and thin walled sections.Īs we receive many questions for this issue I will try to make some Q and A part below:įor a steel member to be designed in accordance with the provisions of EN it has to belong to a corresponding database that is included in Robot and contains that kind of sections am I right?

To have the section verified as a thin walled it has to have one of the 'thin walled' shape symbol assigned. This is what drives the verification path for a given section (I section, channel, angle etc.) according to the selected design code. The steel design module of Robot recognizes the type of the section using the shape type assigned to it.

Marking the thin wall check box is necessary but this is not enough. In summary, I need to know if it is possible to edit the profile and use it my design and analysis, and how to do it. I tried to copy the above profile, create a new database, paste it make the changes but it didn’t work. If I do tools>Section Definition and draw the profiles, does it works? Is it possible to edit bf? I need 75 instead of 80 Is it possible to edit tw? I need 4.75 instead 3.96 I found a very similar profile at Sadepro database (following previous forum discussions – see below), but I still have some doubts: I am designing a portal frame and I need to use cold formed steel as purlins,
