STAAD appears to be incorrectly truncating lines for frequency amplitude pairs and then returning an error. This requires constantly manually fixing this that the lines aren't too long
To allow the program to understand that frequency-amplitude pair data continues on to the next line use a hyphen '-' to get rid of this error
I'm aware that I need the hyphen, the problem is that STAAD removes the hyphen automatically any time the model is edited.
Any update on this, it's a very irritating bug and time consuming to fix
