Yield Strength Rounds Down

Dmitri Babisin — Tue, 03 Dec 2019 15:28:49 GMT

Why does RAM Structural System round down the Yield Strength fy value?
I am located in Canada so if I use american steel then I convert the fy=50 000psi to MPa which is approximately 345MPa. So in the Modeler when laying out the beams I type in 345MPa, then in the Beam Design -> View/Update Beam it says Fy (N/mm2): 345, but when I go to View Results for a closer look it says Grade = 300W (corresponding Design fy=300MPa)?

Now if I use 350MPa it uses the proper yield strength so to me it appears as though there are thresholds which it automatically rounds down to if crossed.

Problem Running Custom Design Steel Beam Table

Background Info:
I am located I am Canada therefor use the ramcan Masters table with metric beam sizes.

I have created a Design Steel Beam Table, but for some reason I get an error when I run it. It says "Error looking up Section W8x10 in Masters Table"? Why doe sit try to lookup a imperial size when the beam table is metric.
