Abstract
The performance of simultaneous application of steel cantilever damper and Shape Memory Alloy (SMA) rods in the reinforced concrete (RC) shear wall was investigated. In this regard, the critical numerical validation of three full-scale experimental models were distinctly performed and the results were analyzed. Various aspects of numerical modelling, including material modelling assumptions, behavioural models, elements, and solution methods were compared with experimental results. Specimens considering SMA rods as well as steel cantilever damper were numerically investigated. The results illustrated that with increasing the SMA rod angle, the maximum force was decreased, and the residual displacement and dissipated energy was improved. Also, comparing the specimen results without the SMA rods and the specimen with the SMA rods showed that despite the positive effect of the SMA rods, which leads to an increase in maximum force and reduction of residual displacement, the dissipated energy was decreased
