Dear sir,
I modeled the same canopy with two method in staad pro.
In first method i am considering slab instead of composite deck.
In second method i am considering composite deck.
But for both cases forces in the members are different and i am applying the same loading for both cases.
For example beam 70 node 3 value of mz at dead load is 1200kn.m (in first case)
and mz at dead load is 2000kn.m (in second case)
Kindly tell me why results are different and which method i should follow?
