The effect of shape memory and super-elastic property are two exclusive features in shape memory alloys. In order to exploit the properties of shape memory effect, alloy needs to be heated but super-elastic property in these alloys will be proposed automatically in case suitable conditions. In case of using shape memory alloys as Longitudinal armatures in reinforced concrete structures considering them buried in concrete, exploitation of shape memory property will have its particular problems that these problems won’t happen about super-elastic property. Considering the high rate of strain capacity 3% to 8% in memory alloys with super-elastic behavior and the limitation of this capacity in concrete, conditions are necessary to be prepared in a way that memory alloy has the opportunity to propose super-elastic property. In this study, with simulating short-square reinforced concrete column experimental model in software ANSYS and in multi-level and increasing process, longitudinal armatures with shape memory alloy material will replace steel armatures with super-elastic behavior will be investigated with making shape memory alloy kind as variable (Copper and nickel-based alloys), the opportunity of super-elastic property emergence in these alloys and with playing the role of longitudinal armature in reinforced concrete column.
