  7. Abstract:
  8. Among different natural disasters, earthquake has always been known as one of the most effective ones on human lives, and this is only because we still cannot predict the exact time and place of its happening. So, giving special attention to the methods which can omit or minimize the damages of this natural event is needed for controlling the loss in the event of an earthquake. On the other hand schools are known as places which are full of people from younger ages for at least half of each day, and they are considered to be not well educated about how to react in an earthquake in comparison to older people and also considered vulnerable at the time of this natural event. According to what mentioned above, having safer schools can help protecting more people especially the most vulnerable stratum of society. The answer for having safer schools is to build safer new schools or retrofit the available schools. To save time and resources it is probably the best to retrofit and rehabilitate the existing schools. According to data from the National Organization of developing, renovating and equipping schools of Iran, among different types of schools which are considered as applicable for retrofitting process, URM structures have the largest share among them. This research was formed to answer the question of “What is the best retrofitting method for URM schools”. To achieve this goal final financial statement of retrofitted schools between 1387 and 1390 was used as documents. A breakdown structure was designed to compare peripheral shotcrete incremental rehabilitation method, as the suggested method, with complete rehabilitation method based on National Seismic Rehabilitation code of Iran. The result of this comparison, justified and explained the acceptance of peripheral shotcrete, based on Incremental Rehabilitation Method, as the best possible method for retrofitting URM schools
