Hi All,

I know that CAESAR-II has function that it can automatically calculate the static seismic g's factor based on ASCE code. It is shown seismic g's factor for horizontal and vertical direction.
In my knowledge, g's factor for horizontal direction is calculated as per para. 13.3.1 of ASCE code.
But, I don't know calculation method for vertical g's factor. Could someone inform me the basis or document for calculation method for vertical seismic that it is using in CAESAR?

Thank you.
