A four-storey reinforced concrete frame structure is situated in Guwahati (Zone V). The height between the floors is 3 m and the total height of the structure is 12 m. The dead load and the regular living load are combined at appropriate floors. The soil beneath the foundation is hard rock, for which the average response acceleration coefficient (Sa/g) is 2.50. Assume that the structure is meant to be utilized as a hospital, for which the importance factor (I) is 1.5. Determine the total base shear using IS 1893 (Part 1): 2002 given total seismic weight W = 7500 kN, response reduction factor R = 5.0 for the special RC moment-resisting frame, and zone factor Z = 0.36.
