Dear Sir/Madam,
Fyi, below image is the assignation of response spectrum in Z direction
In my structure, I've purposely assigned one node (Node 9) between beam 5 & 9. (Refer to image below)
And I've modelled beam 8 without midpoint node assigned to it. (Refer to image below)
When I go to my beam result, noticed that there is Fz on beam 5 & 9 (Although beam 5 & 9 are actually one continuous beam)
and there is no Fz force on beam 8
Could anyone mind explaining it to me? Attached staad file for your reference. Thank you7356.TEST.STD
