Dear Friends,
I'm trying to check the results of floor vibration from STAAD pro, I've modeled very simple floor system with the following properties:
Joist Type : IPE 270
Joist Span: 6.0m
Joist Spacing: 2.0m
Joist Deflection: 4.142 mm
******
Girder Type : IPE 550
Girder Span: 12.0m
Girder Spacing: 6.0m
Girder Deflection: 20.3 mm
*****
Loads : 7.5 kN/m2
Results are shown in the attachment figure, I used the relations in Design guide 11 but I can't varify the following values:
Ds, Dj, Bj, Wj,acceleration.>>> and I don't know how does STAAD assume the value of Damping and Acceleration limit. I mean based on what ?
you can find my model in the attachment too.
