During the last 19 years, more than 100 hospital installations attending a population of 10 to 12 millions in 9 different countries of the American hemisphere, have been affected by earthquakes. One out of 5 collapsed or was demolished due to heavy damage. Hospital buildings are treated in earthquake design codes as a special class with a 20% to 60% increase of the lateral loads prescribed for normal use buildings. Large ductility demands and expected damage using this criteria, do not warrantee the expected performance. This paper proposes a procedure based on the seismic hazard of the site and the desired performance of the building and its contents. Cost implication of this strategy are negligible if compared to the total cost. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
