Earthquake Loads. The following seismic load criteria, based on SNI-1726-2012 as per soil condition of Tanjung Priok. 1. Seismic importance risk factor, I e for power plant project in risk category III is 1.25 (see Table 1 – Risk categories of building and non-building structure for seismic load; and Table 2 – Earthquake importance Factor) 2. Site class is SE, soft soil (see Table 3 – Site Classification) 3. Response spectrum for soft soil (SE) in Tanjung Priok 4. Seismic base shear (V) as bellow (see para 7.81 seismic base shear) : V = C s W Description : C s : The seismic response coefficient W : effective seismic weight C s = S DS /(R/I e ) Description : SDS = Spectral acceleration (g) Period, T (second)
