I've got a STAAD model that's a 3-story simple moment frame. See the screen cap attached.
Let's look at the column on the right. I've specified that I need to keep deflection to h/500 as follows
It is my understanding that's how it's supposed to be specified. Node 4 is 425" up, so 425"/500 = .85" max deflection. However, I get node 4 moving ~2.5" and the unity check says it is deflection controlled but passes. What am I doing wrong here?
STAAD Tech support is being especially slow today for the same question...

Code:
DJ1 1 MEMB 1 TO 3
DJ2 4 MEMB 1 TO 3
DFF 500 MEMB 1 TO 9
