The E value you used was not consistent with the units you used. For unit of KN mm the E should be modified as shown next
DEFINE MATERIAL START
ISOTROPIC STEEL
*E 2.05e+008
E 205
…
I noted that you specified FYLD value for a couple of members and that value is also inconsistent with the unit settings and should be modified as noted below
*FYLD 250000 MEMB 367 368 371 372
FYLD 0.25 MEMB 367 368 371 372
There were some modeling issues. For example member 406 was not split at node 102 which would mean no connectivity between beams 406 and 183. Similar situations exist at other locations in your model too. I fixed these at a number of locations but there are still more which you need to fix. Check the deflected shape and you will know where these connectivity issues are.
You did a code check and member selection for load cases 5 and 6 which are seismic cases acting by themselves. So I commented that out. You may want to do code check for the combinations. Also in order to carry a deflection check for the service cases, you need to define serviceability envelope consisting of certain combinations. Since your combinations seemed to be strength ones, I created a serviceability combination 100, just for demonstration, consisting of DL+LL. Serviceability and Strength envelopes were also added. You can find more details on that at the following wiki
The DFF command was not added for all members. In order to do a deflection check for any member a DFF parameter is essential. I added a DFF 360 ALL command. You may want to modify as needed.
I also commented out a few redundant design commands which you can find in the modified input file that is attached for your reference.
