Abstract

Due to the suitability and ductility of the eccentric bracing system, the effect of reversible materials such as shape memory alloys in reducing the residual displacement at the end of the earthquake is studied. Moreover, seismic evaluation of eccentric bracing dual steel bending frame structures within 5, 10, and 15-stories equipped with shape memory alloy rods were subjected to the non-linear dynamic time history analysis. Maximum absolute displacement of the roof and relative displacement of stories, the maximum residual displacement of the roof, maximum base shear, and roof acceleration in the desired frames were evaluated and compared. Survey results showed that the absolute and relative inter-story drift in all three models due to the lower elastic modulus of shape memory alloys has been greater than models without shape memory alloys. On the other hand, the values of residual displacement, shear stories, and acceleration of the roof of structural models ​ have shown a sudden sharp drop compared to models that have not been equipped with shape memory alloys. Comparison of structural responses in different models also showed a further reduction effect on the plastic displacement of the 5-stories model, base shear, and roof acceleration of 10 and 15-stories structures.
