Load to mass conversion

[Refaat]

Dear Sir

-  Which mass type (global mass & dynamic mass ) shall I use it for my model (concrete tower 21 floor )?

- Shall I activate the mass in three directions (X,Y,Z) or only (X,Y) Because my building height = 75m ?

 Thanks in advance

Changing value in direction may give you the same effect but in fact it rescales whole spectrum so you may get different base shear depending on code requirements (min base shear etc) and then such base shear is multiplied by this factor. So it is recomended to use direction =1 then set factor.
