I'm using ASD 9th edition to check beam box sections. Depth of beam is 110cm and webs are 1.3 thick. According to section F4-2, allowable stress will be lower than 0.4Fy. I remember this was an issue on previous versions and was later fixed for I beams, however for box beams the program still checks against 0.4Fy.

Please attach the rtd file with the test model you made and indicate on the results dialog or the calculation note the verification that you think is done incorrectly. Thank you.
The code you selected in Job Preferences is the old version where implementation of this shear verification procedure in Robot is limited to H and C sections. Please use the new version of the code instead as shown on the attached picture.
