Base Shear Calculation For Seismic Load
Base Shear Calculation For Seismic Load
(OP)
What is the reason behind in excluding live load from calculating base shear for seismic load of a building? Any expert, please share your opinion on this based on IBC, UBC or any applicable codes. Thank you so much.

Also the fact that some live loads won't contribute to the seismic mass due to not being 'fixed' to the structure. If the building shakes left and you loose your footing and are sliding back and forth on the ground - are you contributing the seismic weight of the building?
EDIT: Can't find it now, but there was a great discussion a few months back about considering the full weight of chickens in a multi-storey farm shed contributing to the seismic weight.

However I'm not too familiar with the codes you mentioned in your original post. But the seismic weight is defined as G + 0.3Q in the Australian Standards.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
