Horizontal Base Shear

, 

V = Total holizontal earthquake base shear force

I = Importance factor (see Table 1)

C = Earthquake design coefficient

       

        T = Fundamental period of the structure

        a = acceleration coefficient (see Fig.1)

S = Site factor (see Table 2)

Rf = Structural response factor (see Table 3)

Gg = Gravity load

          Gg = G + ψc ・ Q

           G = Dead load

       ψc  = Live load combination factor

           Q = Live load
