I have trial version of STAAD.Pro software and I am trying to figure out why my calculation are not same as manual one. I have modeled simple structure. But I dont want to have beams 1,27,26,25,24. It is intended that all that beams are one beam and beams 6,11,16,21 are welded to that beam and central beam (there are also beams 3,5,10,15,20 and they are in reality one single beam).

Is that influencing results (Continues load is added to 8 middle beams). I have merged beams 1,27,26,25,24 into single beam , and beams 3,5,10,15,20 into single beam- and beams 2,7,12,17,22 into single beam also - but than it says that I have multiple structures.

Can someone explain how to model intended.

Thank you !
