Modelling and Simulation of Reinforced Concrete Bridges with varying percentages of Shape Memory Alloy Rods

Earthquakes constitute a major problem for mankind resulting in loss of lives and structures. Smart structural materials such as Shape Memory Alloy (SMA) suppress the structural vibration in a structure by adjusting the dynamic performance of the structure. SMA rods are unique for their shape memory...
