2.3 EARTHQUAKE LOAD CALCULATION Example A four story, concrete special moment resisting frame with the properties given below is located on a site in Zone 4 with an undetermined soil profile type. The site is situated 7.5 km away from potential seismic source type A. Calculate the seismic base shear. For slabs, t = 100 mm. W wall = 2.5 kPa (no interior walls).
