Abstarct: Recovery of building losses caused by building demolition is an idea that has been raised in recent years to promote environmental indicators and Prevention of pollution of water and soil and air of cities. This means that utilization of recovered aggregate from the one hand, with the accumulation of accumulated waste during the past years, will have a beneficial effect on the environment, and on the other hand, the use of these materials in developmental use, leads to Reducing the use of natural aggregate mines and preservation of these resources for the ascendants. The use of old crushed concrete as part of aggregate or aggregates of new concrete can be a good example to increase the life of concrete. Concrete industry employs approximately 10 billion tons of sand and natural stone around the world, and More than, generates more than 10 billion tons of construction waste. In this thesis the seismic performance of frxame specimens were made with the RCA replacement percentage equal to 30%, 50% and 100%, have been compared with conventional concrete frxame. The samples were evaluated for lengths of L= 3250mm, 1.5L and 2L, height of one floor, two floors, three floors, and various percentages of using reinforcement in columns of 1.3%, 1.8% and 2.3%. The findings of this study indicate that increasing the percentage of use of RCA in the frxames has reduced the amount of yield load, the ultimate load and the maximum load, although the maximum reduction in these loads was about 15%. Also, according to the capacity curves, it is concluded that the energy dissipation capacity, Also, according to the capacity curves, it is concluded that the energy dissipation capacity, the stiffness reduction values of the frxames made of ordinary concrete and recycled concrete, except for the use of 100% RCA replacement, are comparable and not very different. Generally, after the seismic analysis of these frxames, it can be concluded that the seismic behavior of frxames made with recycled concrete decreases slightly with the increase in the amount of RCA compared to conventional concrete.However, overall, frxames made from RCA display logical behavior against earthquake effects.
