scale factor on ETABS
(OP)
Hi,
can anyone help me on how to get the scale factor in the input response spectra? I'm new to dynamic analysis so I need some help. thanks.

RE: scale factor on ETABS
In general, this is a balancing factor of your Response spectrum base shear to the static base shear. For this, you should know your static base shear as per your Code of Practice. This can be calculated by selecting relevant Code and using Auto Seismic option in load cases menu in ETABS. Depending upon your framing system different Code allows different %age of base shear to be balanced. Normally, It is 90% of the static (Codec) base shear.
