ETABS story accelarations

[niravshah1964]

ETABS when displays story acceleration values, what does that value physical mean. Example:

in UX direction acceleration of 0.8 means acceleration in X direction is 0.8 x g??

Can anybody confirm

Thanks in advance

I have got the answer: It is in the units displayed in main screen, so 0.8 in Knm unit is 0.8 m/sqsec in X direction.

What is human comfort acceleration?? any idea.

I think that is the reason Tuned mass dampner are provided in very tall bldg, to reduce acc against excitation due to cyclonic winds.
