Found it very interesting to calculate the factors taken under consideration by the software, while checking the vertical deflections in steel frame members. Here they are:
Dead load scale factor: 1.3-1.5
Live load scale factor: 1.8-3.3
In order to check the results, a single story, one bay steel building has been designed. L/B/H=8.00/8.00/3.00m Beam sections IPE240, Column sections HEB300, slab h=20cm with stiffness modifier 0.50.
The results given from the steel frame design of the beams:
-for Dead Load 19.2mm, instead of 14.3mm (ScF=19.2/14.3=1.34)
-for Live Load 44.8mm, instead of 14.0mm (ScF=44.8/14.0=3.2)
-for ADL, δ=5.6mm, so for for Super DL+Live Load 50.2mm, instead of 5.6+14.0=19.6mm
Until now, couldn't find the reason for this. Any comment appreciated.
