Scaling Down Design Values of Combined Response Spectrum
Scaling Down Design Values of Combined Response Spectrum
(OP)
Good morning guys,
I have done a response spectrum analysis to a 16-story building and I got that my dynamic base shear is bigger than my static base shear. Since i don't need to scale up my dynamic base shear as per asce7 12.9.4, can i instead scale it down?? not to an 85% but to a 100% (dynamic base shear = static base shear)?
I would like to hear your thoughts on this,
Thanks

But if it actually is higher I believe all codes state something along the lines of scale up to a minimum of 100%, otherwise if over 100% you use that value as you are not required to scale it up.
