Greeting of the day !!
I have a doubt in staad for Plate elements. 3 different model have been prepared.
Case 1: Frame without Plate element
Case 2 : Frame with plate element (Plate element with nodes at 4 beam-column junctions
Case 3 : Frame with small plates of size 0.5 x 0.4 meter
But the results are exorbitantly different.
Case 1: Resultant Displacement : 45.226 mm, Mz = 141.249 KN-meter
Case 2: Resultant Displacement : 35.572 mm, Mz = 134.373 KN-meter
Case 3: Resultant Displacement : 39.734 mm, Mz = 136.507 KN-meter
Please note that only stiffness of plates have been considered in the analysis.
Staad Files & excel comparison is attached for reference.
Kindly explain, which case ideally to be considered for design.[View:/cfs-file/__key/communityserver-discussions-components-files/5932/Staad-With-_2600_-without-plates.zip:940:0]
