Eccentric weight of 1 MT is placed at node 18 of a structure in attached STAAD file.
Eccentricity of weight is 1m.
Seismic load as per STAAD output is 2.5MT.
Seismic load of 2.5MT should cause moment of 2.5T-m about Y axis at support.
Instead of 2.5T-m, STAAD output is showing moment of 1.12T-m.
Would appriciate an earli clarification.[View:/cfs-file/__key/communityserver-discussions-components-files/5932/Without-torsion.std:940:0]
