P = CeCqqsIw(5.20-1)
(Seismic Coefficient, depending on seismic zone and soil profile type)(Table 5-R)
(Importance factor, depending on the use of the building)(Table 5-K)
(The total Seismic Dead Load) (Section 220.127.116.11)
(Design Base Shear)
(Response modification factor, representing Over Strength and global ductility capacity of lateral force-resisting systems)(Table 5-N)
(Elastic fundamental Time Period of the structure) To be calculated as stated in Section 18.104.22.168
Seismic dead load, W, is the total dead load and applicable portions of other loads listed below.
Where Ftis the concentrated force at the top: Ft = 0.07 TV
∆M = 0.7 R ∆S (5.30-17)
