The expected performance of structures is controlled by assigning each structure to one of four occupancy categories (I through IV). This assignment determines the , ( I_E ), which is 1.25 for Category III structures and 1.5 for Category IV structures. The purpose is to improve the capability of essential facilities—such as hospitals, emergency response centers, or hazardous material storage facilities—to function during and after design earthquakes. asce 7-05 seismic pdf
